[blackcat] L2 Ehlers Autocorrelation PeriodogramLevel: 2 Background John F. Ehlers introduced Autocorrelation Periodogram in his "Cycle Analytics for Traders" chapter 8 on 2013. Function Construction of the autocorrelation periodogram starts with the autocorrelation function using the minimum three bars of averaging. The cyclic information is extracted using a discrete Fourier transform (DFT) of the autocorrelation results. This approach has at least four distinct advantages over other spectral estimation techniques. These are: 1. Rapid response. The spectral estimates start to form within a half-cycle period of their initiation. 2. Relative cyclic power as a function of time is estimated. The autocorrelation at all cycle periods can be low if there are no cycles present, for example, during a trend. Previous works treated the maximum cycle amplitude at each time bar equally. 3. The autocorrelation is constrained to be between minus one and plus one regardless of the period of the measured cycle period. This obviates the need to compensate for Spectral Dilation of the cycle amplitude as a function of the cycle period. 4. The resolution of the cyclic measurement is inherently high and is independent of any windowing function of the price data. The dominant cycle is extracted from the spectral estimate in the next block of code using a center-of-gravity (CG) algorithm. The CG algorithm measures the average center of two-dimensional objects. The algorithm computes the average period at which the powers are centered. That is the dominant cycle. The dominant cycle is a value that varies with time. The spectrum values vary between 0 and 1 after being normalized. These values are converted to colors. When the spectrum is greater than 0.5, the colors combine red and yellow, with yellow being the result when spectrum = 1 and red being the result when the spectrum = 0.5. When the spectrum is less than 0.5, the red saturation is decreased, with the result the color is black when spectrum = 0.

Bitlinc MARSI Study AST w/ Take Profit & Stop loss - beta 0.1This script is beta 0.1 - will update as soon as the script is tradable This script is based on AST on a 10 minute timeframe. You can change the asset and the timeframe for any asset you want to trade, but for it to work correct ALL settings have to be testes in the Strategy section of the TradingView. Each assets and timeframe require a different mixture of settings. This is NOT a one settings fits all trading for all assets on any timeframe. Below are the settings and explanation on how it works. How it fires a buy / sell: The script will plot an RSI with upper and lower bands in a separate indicator window. The idea behind this script is to fire a LONG when MA crosses OVER lower band and fire a SHORT when the MA crosses under the lower band. Each order that fires is an OCO (Order Cancels Order) for pyramiding. Settings: You have full control of these settings as mentioned above, you must configure every part of this script for each asset and timeframe you trade. - Length of MA - Length - Upper bands of RSI - Lower bands of RSI - Take profit percentage - Stop loss percentage - Month to start and end the strategy (within 2020) - Day to start and end the strategy (within 2020) - Quantity type - Slippage - Pyramiding ***Remember that after the signal to enter or exit a trade is fired, the alert will trigger AFTER the close of the candle that caused the tigger to fire

[blackcat] L2 The Distance Coefficient Ehlers FilterLevel: 2 Background John F. Ehlers introuced the Distance Coefficient Ehlers Filter in his "Rocket Science for Traders" chapter 18 on 2001. Function Dr. Ehlers considered the gray shading levels as distances, he had away of computing filter coefficients in terms of sharpness of the edge. White is the maximum distance in one direction from the median gray, and black is the maximum distance in the other direction. In this sense, distance is a measure of departure from the edge, taking into account the edge sharpness. Transitioning to price charts, the difference in prices can be imagined as a distance. Recalling the Pythagorean Theorem (which the length of the hypotenuse of a triangle is equal to the sum of the squares of the lengths of the other two sides), Dr Ehlers applied it to the needs and say that a generalized length at any data sample is the square root of the sum of the squares of the price difference between that price and each of the prices back for the length of the filter window. The distances squared at each data point are the coefficients of the Ehlers filter.

Computing FIR Filters Using Arrays [WMA Example]Over the years, many FIR filters have been proposed by the Pine community, with the standard way of computing them being `for` loops. The arrival of arrays allows for a new, more efficient way to compute them. This script provides a template showing how you can compute FIR filters using Pine arrays. FIR Filters FIR stands for "Finite Impulse Response", and is associated with types of filters whose impulse response reaches a steady state. FIR filters are calculated using convolution, or more simply put, using a weighted sum between a set of filter coefficients and past input values over a finite window. In Pine, FIR filters are generally computed inside a `for` loop executing three processes: 1- Computing the coefficients. 2- Summing all the computed coefficients. 3- Performing the weighted sum between the inputs values and the computed coefficients. Then we divide the result of our weighted sum by the sum of the coefficients obtained in step 2. Because the computations inside the `for` loop execute on each bar, execution time can be significant when the calculation of coefficients is complex. This is where arrays are handy, as we can compute the coefficients just once, store them into an array, and use them in a weighted sum without the need to recalculate them over and over. This drastically reduces the computation time required to calculate a FIR filter. The new `array.sum()` function helps eliminate step 2, thus further decreasing computation time. How to Use This Template All you need to do is to put the code that computes your coefficients in the first `for` loop (variable `w`). If the code that computes your coefficients contains more than one line, just make sure your final coefficient is placed in variable `w` (or change the `value` argument in `array.push()`). Another option is to declare a function that computes the coefficients and use it instead of variable `w`. Look first. Then leap.

Over time, most successful strategies will be added with an option to set strategy-specific alerts . TST Signals & Alerts will draw signals on the chart when the entry conditions are met. You can also opt for displaying indicators . My script is meant for beginners but can be used by veterans too. Just pick one or two strategies, you don't want to flood your chart with conflicting signals. You may want to support your trades with a proper analysis. Is the market trending? Is there a fundament around the corner? If a new signal occurs when there is still an open position, you are not supposed to take another. The current version includes MACD and ADX + BB and BB strategies. MACD strategy: ►Buy, when MACD crosses below the signal line when it is negative. The price must also be above 200 EMA. ►Sell, when MACD crosses above the signal line when it is positive. The price must also be below 200 EMA. ►This strategy was tested on 15-minute charts of EURUSD with reward-to-risk ratio 1,5 and win rate of 61% over 100 trades. ►►►MACD has to be added to your chart separately because it needs a new window. Ticking display indicators will not add MACD to your chart. ►►►MACD was also tested by a different channel I made a script for. You can view the results and the script here: ADX + BB strategy: ►Buy, when the price is above 200 EMA and ADX becomes higher than 25. ►Sell, when the price is below 200 EMA and ADX becomes higher than 25. ►Stop-loss is either 200 EMA or Bollinger Bands level.

MobilityThe indicator measure realized mobility of the underlying in the terms of V.Kurbakovsky. It is not an exact realization without access to bid and ask prices, but you can choose source prices in the settings window. The indicator can be used to estimate the degree of variation of the underlying price in volatility trading. It is advised to use it on a 1M (1 minute) timeframe. In the calculations the mobility will be normalized to a day. In Minutes in period setting you can specify the number of the estimating periods during MOEX trading session, which is 810 minutes. Thus, mobility is measured in points per day.

Delta Volume Candles [LucF]█  OVERVIEW This indicator plots on-chart volume delta information using candles that can replace your normal candles, tops and bottoms appended to normal candles, optional MAs of those tops and bottoms levels, a divergence channel and a chart background. The indicator calculates volume delta using intrabar analysis, meaning that it uses the lower timeframe bars constituting each chart bar. █  CONCEPTS Volume Delta ​The ​volume delta concept divides a bar's ​volume in "up" and "down" ​volumes. The delta is calculated by subtracting down ​volume from up ​volume. Many calculation techniques exist to isolate up and down ​volume within a bar. The simplest use the polarity of interbar price changes to assign their ​volume to up or down slots, e.g., On Balance Volume or the Klinger Oscillator . Others such as Chaikin Money Flow use assumptions based on a bar's OHLC values. The most precise calculation method uses tick data and assigns the ​volume of each tick to the up or down slot depending on whether the transaction occurs at the bid or ask price. While this technique is ideal, it requires huge amounts of data on historical bars, which considerably limits the historical depth of charts and the number of symbols for which tick data is available. Furthermore, historical tick data is not yet available on TradingView. This indicator uses intrabar analysis to achieve a compromise between the simplest and most precise methods of calculating ​volume delta. It is currently the most precise method usable on TradingView charts. TradingView's Volume Profile built-in indicators use it, as do the CVD - Cumulative ​Volume Delta Candles and CVD - Cumulative Volume Delta (Chart) indicators published from the TradingView account . My Delta Volume Channels and Volume Delta Columns Pro indicators also use intrabar analysis. Other ​volume delta indicators such as my Realtime 5D Profile use realtime chart updates to calculate volume delta without intrabar analysis, but that type of indicator only works in real time; they cannot calculate on historical bars. This is the logic I use to determine the polarity of intrabars, which determines the up or down slot where its ​volume is added:  • If the intrabar's open and close values are different, their relative position is used.  • If the intrabar's open and close values are the same, the difference between the intrabar's close and the previous intrabar's close is used.  • As a last resort, when there is no movement during an intrabar, and it closes at the same price as the previous intrabar, the last known polarity is used. Once all intrabars making up a chart bar have been analyzed and the up or down property of each intrabar's ​volume determined, the up volumes are added, and the down volumes subtracted. The resulting value is ​volume delta for that chart bar, which can be used as an estimate of the buying/selling pressure on an instrument. Not all markets have volume information. Without it, this indicator is useless. Intrabar analysis Intrabars are chart bars at a lower timeframe than the chart's. The timeframe used to access intrabars determines the number of intrabars accessible for each chart bar. On a 1H chart, each chart bar of an active market will, for example, usually contain 60 bars at the lower timeframe of 1min, provided there was market activity during each minute of the hour. This indicator automatically calculates an appropriate lower timeframe using the chart's timeframe and the settings you use in the script's "Intrabars" section of the inputs. As it can access lower timeframes as small as seconds when available, the indicator can be used on charts at relatively small timeframes such as 1min, provided the market is active enough to produce bars at second timeframes. The quantity of intrabars analyzed in each chart bar determines:  • The precision of calculations (more intrabars yield more precise results).  • The chart coverage of calculations (there is a 100K limit to the quantity of intrabars that can be analyzed on any chart,   so the more intrabars you analyze per chart bar, the less chart bars can be calculated by the indicator). The information box displayed at the bottom right of the chart shows the lower timeframe used for intrabars, as well as the average number of intrabars detected for chart bars and statistics on chart coverage. Balances This indicator calculates five balances from volume delta values. The balances are oscillators with a zero centerline; positive values are bullish, and negative values are bearish. It is important to understand the balances as they can be used to:  • Color candle bodies.  • Calculate body and top and bottom divergences.  • Color an EMA channel.  • Color the chart's background.  • Configure markers and alerts. The five balances are: 1 — Bar Balance : This is the only balance using instant values; it is simply the subtraction of the down volume​ from the up volume​ on the bar, so the instant volume delta for that bar. 2 — Average Balance : Calculates a distinct EMA for both the up and down volumes, and subtracts the down EMA from the up EMA.   The result is akin to MACD's histogram because it is the subtraction of two moving averages. 3 — Momentum Balance : Starts by calculating, separately for both up and down volumes, the difference between the same EMAs used in "Average Balance" and   an SMA of twice the period used for the "Average Balance" EMAs. The difference for the up side is subtracted from the difference for the down side,   and an RSI of that value is calculated and brought over the −50/+50 scale. 4 — Relative Balance : The reference values used in the calculation are the up and down EMAs used in the "Average Balance".   From those, we calculate two intermediate values using how much the instant up and down volumes on the bar exceed their respective EMA — but with a twist.   If the bar's up volume​ does not exceed the EMA of up volume​, a zero value is used. The same goes for the down volume​ with the EMA of down volume​.   Once we have our two intermediate values for the up and down volumes exceeding their respective MA, we subtract them. The final value is an ALMA of that subtraction.   The rationale behind using zero values when the bar's up/down volume​ does not exceed its EMA is to only take into account the more significant volume​.   If both instant volume​ values exceed their MA, then the difference between the two is the signal's value.   The signal is called "relative" because the intermediate values are the difference between the instant up/down volumes and their respective MA.   This balance flatlines when the bar's up/down volumes do not exceed their EMAs, which makes it useful to spot areas where trader interest dwindles, such as consolidations.   The smaller the period of the final value's ALMA, the more easily it will flatline. These flat zones should be considered no-trade zones. 5 — Percent Balance : This balance is the ALMA of the ratio of the "Bar Balance" over the total volume for that bar. From the balances and marker conditions, two more values are calculated: 1 — Marker Bias : This sums the up/down (+1/‒1) occurrences of the markers 1 to 4 over a period you define, so it ranges from −4 to +4, times the period.   Its calculation will depend on the modes used to calculate markers 3 and 4. 2 — Combined Balances : This is the sum of the bull/bear (+1/−1) states of each of the five balances, so it ranges from −5 to +5. The periods for all of these balances can be configured in the "Periods" section at the bottom of the script's inputs. As you cannot see the balances on the chart, you can use my Volume Delta Columns Pro indicator in a pane; it can plot the same balances, so you will be able to analyze them. Divergences In the context of this indicator, a divergence is any bar where the bear/bull state of a balance (above/below its zero centerline) diverges from the polarity of a chart bar. No directional bias is assigned to divergences when they occur. Candle bodies and tops/bottoms can each be colored differently on divergences detected from distinct balances. Divergence Channel The divergence channel is the space between two levels (by default, the bar's open and close ) saved when divergences occur. When price (by default the close ) has breached a channel and a new divergence occurs, a new channel is created. Until that new channel is breached, bars where additional divergences occur will expand the channel's levels if the bar's price points are outside the channel. Prices breaches of the divergence channel will change its state. Divergence channels can be in one of three different states:  • Bull (green): Price has breached the channel to the upside.  • Bear (red): Price has breached the channel to the downside.  • Neutral (gray): The channel has not yet been breached. █  HOW TO USE THE INDICATOR I do not make videos to explain how to use my indicators. I do, however, try hard to include in their description everything one needs to understand what they do. From there, it's up to you to explore and figure out if they can be useful in your trading practice. Communicating in videos what this description and the script's tooltips contain would make for very long videos that would likely exceed the attention span of most people who find this description too long. There is no quick way to understand an indicator such as this one because it uses many different concepts and has quite a bit of settings one can use to modify its visuals and behavior — thus how one uses it. I will happily answer questions on the inner workings of the indicator, but I do not answer questions like "How do I trade using this indicator?" A useful answer to that question would require an in-depth analysis of who you are, your trading methodology and objectives, which I do not have time for. I do not teach trading. Start by loading the indicator on an active chart containing volume information. See here if you need help. The default configuration displays:  • Normal candles where the bodies are only colored if the bar's volume has increased since the last bar.   If you want to use this indicator's candles, you may want to disable your chart's candles by clicking the eye icon to the right of the symbol's name in the top left of the chart.  • A top or bottom appended to the normal candles. It represents the difference between up and down volume for that bar   and is positioned at the top or bottom, depending on its polarity. If up volume is greater than down volume, a top is displayed. If down volume is greater, a bottom is plotted.   The size of tops and bottoms is determined by calculating a factor which is the proportion of volume delta over the bar's total volume.   That factor is then used to calculate the top or bottom size relative to a baseline of the average candle body size of the last 100 bars.  • An information box in the bottom right displaying intrabar and chart coverage information.  • A light red background when the intrabar volume differs from the chart's volume by more than 1%. The script's inputs contain tooltips explaining most of the fields. I will not repeat them here. Following is a brief description of each section of the indicator's inputs which will give you an idea of what the indicator can do: Normal Candles is where you configure the replacement candles plotted by the script. You can choose from different coloring schemes for their bodies and specify a unique color for bodies where a divergence calculated using the method you choose occurs. Volume Tops & Botttoms is where you configure the display of tops and bottoms, and their EMAs. The EMAs are calculated from the high point of tops and the low point of bottoms. They can act as a channel to evaluate price, and you can choose to color the channel using a gradient reflecting the advances/declines in the balance of your choice. Divergence Channel is where you set up the appearance and behavior of the divergence channel. These areas represent levels where price and volume delta information do not converge. They can be interpreted as regions with no clear direction from where one will look for breaches. You can configure the channel to take into account one or both types of divergences you have configured for candle bodies and tops/bottoms. Background allows you to configure a gradient background color that reflects the advances/declines in the balance of your choice. You can use this to provide context to the volume delta values from bars. You can also control the background color displayed on volume discrepancies between the intrabar and the chart's timeframe. Intrabars is where you choose the calculation mode determining the lower timeframe used to access intrabars. The indicator uses the chart's timeframe and the type of market you are on to calculate the lower timeframe. Your setting there should reflect which compromise you prefer between the precision of calculations and chart coverage. This is also where you control the display of the information box in the lower right corner of the chart. Markers allows you to control the plotting of chart markers on different conditions. Their configuration determines when alerts generated from the indicator will fire. Note that in order to generate alerts from this script, they must be created from your chart. See this Help Center page to learn how. Only the last 500 markers will be visible on the chart, but this will not affect the generation of alerts. Periods is where you configure the periods for the balances and the EMAs used in the indicator. The raw values calculated by this script can be inspected using the Data Window. █  INTERPRETATION Rightly or wrongly, volume delta is considered by many a useful complement to the interpretation of price action. I use it extensively in an attempt to find convergence between my read of volume delta and price movement — not so much as a predictor of future price movement. No system or person can predict the future. Accordingly, I consider people who speak or act as if they know the future with certainty to be dangerous to themselves and others; they are charlatans, imprudent or blissfully ignorant. I try to avoid elaborate volume delta interpretation schemes involving too many variables and prefer to keep things simple:  • Trends that have more chances of continuing should be accompanied by VD of the same polarity.   In trends, I am looking for "slow and steady". I work from the assumption that traders and systems often overreact, which translates into unproductive volatility.   Wild trends are more susceptible to overreactions.  • I prefer steady VD values over wildly increasing ones, as large VD increases often come with increased price volatility, which can backfire.   Large VD values caused by stopping volume will also often occur on trend reversals with abnormally high candles.  • Prices escaping divergence channels may be leading a trend in that direction, although there is no telling how long that trend will last; could be just a few bars or hundreds.   When price is in a channel, shifts in VD balances can sometimes give us an idea of the direction where price has the most chance of breaking.  • Dwindling VD will often indicate trend exhaustion and predate reversals by many bars, but the problem is that mere pauses in a trend will often produce the same behavior in VD.   I think it is too perilous to infer rigidly from VD decreases. Divergence Channel Here I have configured the divergence channels to be visible. First, I set the bodies to display divergences on the default Bar Balance. They are indicated by yellow bodies. Then I activated the divergence channels by choosing to draw levels on body divergences and checked the "Fill" checkbox to fill the channel with the same color as the levels. The divergence channel is best understood as a direction-less area from where a breach can be acted on if other variables converge with the breach's direction: Tops and Bottoms EMAs I find these EMAs rather interesting. They have no equivalent elsewhere, as they are calculated from the top and bottom values this indicator plots. The only similarity they have with volume-weighted MAs, including VWAP, is that they use price and volume. This indicator's Tops and Bottoms EMAs, however, use the price and volume delta. While the channel differs from other channels in how it is calculated, it can be used like others, as a baseline from which to evaluate price movement or, alternatively, as stop levels. Remember that you can change the period used for the EMAs in the "Periods" section of the inputs. This chart shows the EMAs in action, filled with a gradient representing the advances/decline from the Momentum balance. Notice the anomaly in the chart's latest bars where the Momentum balance gradient has been indicating a bullish bias for some time, during which price was mostly below the EMAs. Price has just broken above the channel on positive VD. My interpretation of this situation would be that it is a risky opportunity for a long trade in the larger context where the market has been in a downtrend since the 5th. Intrepid traders choosing to enter here could do so with a "make or break" tight stop that will minimize their losses should the market continue its downtrend while hopefully preserving the potential upside of price continuing on the longer-term uptrend prevalent since the 28th: █  NOTES Volume If you use indicators such as this one which depends on volume information, it is important to realize that the volume data they consume comes from data feeds, and that all data feeds are NOT created equally. Those who create the data feeds we use must make decisions concerning the nature of the transactions they tally and the way they are tallied in each feed, and these decisions affect the nature of our volume data. My Volume X-ray publication discusses some of the reasons why volume information from different timeframes, brokers/exchanges or sectors may vary considerably. I encourage you to read it. This indicator's display of a warning through a background color on volume discrepancies between the timeframe used to access intrabars and the chart's timeframe is an attempt to help you realize these variations in feeds. Don't take things for granted, and understand that the quality of a given feed's volume information affects the quality of the results this indicator calculates. Markets as ecosystems I believe it is perilous to think that behavioral patterns you discover in one market through the lens of this or any other indicator will necessarily port to other markets. While this may sometimes be the case, it will often not. Why is that? Because each market is its own ecosystem. As cities do, all markets share some common characteristics, but they also all have their idiosyncrasies. A proportion of a city's inhabitants is always composed of outsiders who come and go, but a core population of regulars and systems is usually the force that actually defines most of the city's observable characteristics. I believe markets work somewhat the same way; they may look the same, but if you live there for a while and pay attention, you will notice the idiosyncrasies. Some things that work in some markets will, accordingly, not work in others. Please keep that in mind when you draw conclusions. On Up/Down or Buy/Sell Volume Buying or selling volume are misnomers, as every unit of volume transacted is both bought and sold by two different traders. While this does not keep me from using the terms, there is no such thing as “buy only” or “sell only” volume. Trader lingo is riddled with peculiarities. Without access to order book information, traders work with the assumption that when price moves up during a bar, there was more buying pressure than selling pressure, just as when buy market orders take out limit ask orders in the order book at successively higher levels. The built-in volume indicator available on TradingView uses this logic to color the volume columns green or red. While this script’s calculations are more precise because it analyses intrabars to calculate its information, it uses pretty much the same imperfect logic. Until Pine scripts can have access to how much volume was transacted at the bid/ask prices, our volume delta calculations will remain a mere proxy. Repainting  • The values calculated on the realtime bar will update as new information comes from the feed.  • Historical values may recalculate if the historical feed is updated or when calculations start from a new point in history.  • Markers and alerts will not repaint as they only occur on a bar's close. Keep this in mind when viewing markers on historical bars,   where one could understandably and incorrectly assume they appear at the bar's open. To learn more about repainting, see the Pine Script™ User Manual's page on the subject . Superfluity In "The Bed of Procrustes", Nassim Nicholas Taleb writes: To bankrupt a fool, give him information . This indicator can display a lot of information. The inevitable adaptation period you will need to figure out how to use it should help you eliminate all the visuals you do not need. The more you eliminate, the easier it will be to focus on those that are the most useful to your trading practice. Don't be a fool. █  THANKS Thanks to alexgrover for his Dekidaka-Ashi indicator. His volume plots on candles were the inspiration for my top/bottom plots. Kudos to PineCoders for their libraries. I use two of them in this script: Time and lower_tf . The first versions of this script used functionality that I would not have known about were it not for these two guys: — A guy called Kuan who commented on a Backtest Rookies presentation of their Volume Profile indicator. — theheirophant , my partner in the exploration of the sometimes weird abysses of request.security() ’s behavior at lower timeframes.

MFI RSI w STOCH OVERLAY V3Combines: Relative Strength (purple) and RSI Stoch (Orange/gray), Money Flow (green) all in one indicator window. On screen indicator text identifier will read in this order: "RSI/STOCH/MFI V3" // Changes from original version \\ It was important to bring forth the RSI indicator as the most visually important line and its relationship to the background. A: Major visual changes from my first published one..as default now 1: Increased RSI line to size 3 2: Increased MFI line to size 2 3: Separated all Bar Line Fields in the background for custom editing, total of 5 now. Much easier to distinguish when the RSI enters these fields. B: Other major changes as default now 1: Sped up the indicators from 14 to 11, for quicker response. (user can adjust back to 14 or another number) 2: Increased user friendly inputs to adjust colors, lines, data, etc. 3: (darken / lighten and change background colors, increase/decrease line strengths and colors, adjust field data inputs) Enjoy and Good Luck Trading.

Better Bollinger Bands (now open source)General purpose Bollinger band indicator with a number of configuration options and some additional color-coded information. The main advantages of it over standard Bollinger bands are: 1) Better statistics: * Uses volume weighted moving averages, variance, and standard deviation by default. The volume dependence can be disabled with a checkbox option, but generally makes it more responsive improves its ability to distinguish true outlier events from random variation. * Lets you pick between different time windows (simple, sawtooth (WMA), exponential) in addition to the volume weighting, with appropriate Bessel corrections to make the estimators unbiased and to get consistent result for different weights. * Has a checkbox option to use a linear regression in the band calculation if you don't want average momentum to be counted in the volatility. This turns the centerline into a last squares moving average, and the band width at each time step is given by the variance away from the regression line instead of from a moving average. Weights in the least squares regression are changed according to the other options. For tickers with a strong long-term trend this makes the bands track the price action more closely. 2) Geometric * This does all calculations on log(price) instead of the prices themselves. * Makes almost no difference in most cases, but gives better results on charts with strongly exponential behaviour that range between several orders of magnitude. * Properly centered around price action on log plots. * Will never annoy you by rescaling a log plot due to a negative lower band. The lower band is always positive for positive prices. 3) Some built in oscillators. * This aims to reduce clutter by building in some other indicators into the band color scheme. You can pick between various momentum & RSI operators to color the center line and the bands, or leave the bands plain. I've been using these bands myself for a few months & have been gradually adding functionality & polish. Feel free to comment, or to refer to me if you borrow any ideas.

Dow Factor Relative Strength IndexThis script was written to create a new, rapid relative strength index inspired by the Dow Theory. More info about Dow Theory : www.investopedia.com According to the Dow Theory, volume should confirm market trends. The correlation coefficient between prices and volume is negative in weakening trends and negative trends , positive in strengthening or positive trends.a factor was formed based on the correlation coefficient between volume and prices. This factor was added to the relative strength index. Period 5 is selected because the volume is very volatile and can be slow. You can use the period you want, but I recommend the period as a minimum of 5. It is suitable for all instruments and timeframes and thanks to its design, it provides control over gradual buying and selling points. I haven't fully tested it, it's open to updates. For now, just use it to create ideas. If I find it necessary, I'll update after the tests. If you have suggestions on these issues, Leave your comments in the comment window. This code is open source under the MIT license. If you have any improvements or corrections to suggest, please send me a pull request via the github repository github.com Stay tuned , best regards.

Bilateral Stochastic Oscillator StrategyIntroduction Strategy based on the bilateral stochastic oscillator, this oscillator aim to detect trends and possible reversal points of the current trend. The oscillator is composed of 1 bull line in blue and 1 bear line in red as well as a signal line in orange, the strategy have many options such as two different strategy framework and a martingale mode. If you require more information about the indicator go check it into my uploaded indicators. Strategy Frameworks There are two frameworks available that can be selected from the strategy settings window. Both have the same closing conditions, the "Bull/Bear Cross" entry conditions are : Buy : when the bull line cross over the bear line Sell : when the bear line cross over the bull line The "Signal Cross" entry conditions are : Buy : when the bull line cross over the signal line Sell : when the bear line cross over the signal line Both have the same close conditions that is : close when bull/bear cross under the signal line. Introduction To Martingale The martingale money management system consist to double the order size after a loosing trade and can be described as a 2^x where x is the current number of loosing trades since the last win trade, when we win a trade the order size return to the default order size. Therefore our order size function is based on exponential growth. This system enable the trader to win back his previous losses plus a potential profit, martingales must always be used with stops and sometimes take profits in order to get control in a strategy. It must always be taken into account that in a series of losses the balance can exponentially decay thus ending to 0 in a matter of trades, this is why it is not recommended to use such system. The strategy allow you to select a martingale multiplier that can be inferior to 2 thus limiting risks, a multiplied of 1 disable the martingale. Results Those are the some statistics of the strategy applied to some forex majors by using the default settings in a time frames of 15 minutes. //------------------------------------------------------- EURUSD - Order Size 1000 - Spread 0.0002 Profit : $ 21.08 Trades : 19 PP : 57.89 % Profit Factor : 3.228 Max Drawdown : -$ 3.81 Average Trade : $ 1.11 //------------------------------------------------------- GBPUSD - Order Size 1000 - Spread 0.0002 Profit : $ 2.31 Trades : 20 PP : 55 % Profit Factor : 0.938 Max Drawdown : -$ 20.29 Average Trade : $ 0.12 //------------------------------------------------------- EURAUD - Order Size 1000 - Spread 0.0002 Profit : -$ 9.22 Trades : 20 PP : 40 % Profit Factor : 0.698 Max Drawdown : -$ 23.44 Average Trade : $ 0.46 //------------------------------------------------------- EURCHF - Order Size 1000 - Spread 0.0002 Profit : $ 1.58 Trades : 24 PP : 54.17 % Profit Factor : 1.103 Max Drawdown : -$ 7.23 Average Trade : $ 0.07 //------------------------------------------------------- Conclusions Based on the results the strategy does not posses the sufficient performance in order to apply a martingale or any other growth systems as order size. Parameters might be subject to drastic changes depending on the market/time-frame in order to return long-term positive results. I let you draw your conclusions.

Percentage OscillatorUsing momentum calculations on multiple time frames and adding everything together into 4 separate directions: 1- green: the strength and momentum in +45 to +90 degrees angle 2- blue: the strength and momentum in 0 to +45 degrees angle 3- orange: the strength and momentum in 0 to -45 degrees angle 4- red: the strength and momentum in -45 to -90 degrees angle Single parameter to control the size of the largest moving window. Uptrend is green with orange corrections Downtrend is red with blue corrections When downtrend turns into uptrend, blue becomes green When uptrend turns into downtrend, orange becomes red The natural cycle of the market is RED->BLUE->GREEN->ORANGE and so on, you will see the cycle repeats itself 3 times before a break up\down. The strength of the movement depends on the height and width of all the waves that created the 3 cycle movement (reminds Elliot in an oscillatory representation) The script is provided as is, there are no trading strategies implied or recommended. Feel free to PM with questions

Zero Phase Filtering [Repaint] - ExperimentalImportant ! The indicator is for experimental purpose only, it must not be used as a decisional tool but only as a visual one (like Zig-Zag, Fractal etc). The information this indicator display is uncertain and subject to drastic changes over time. If you have further question feel free to pm me. Introduction Most of the filters you will find are causal, this mean that they depend on present and past input values, this explain the lag they produce. Non causal filters however will use future input values. A well know way to get a zero-phase filter is by using the forward backward method, but this is not possible in pinescript as i recall. So we have to use some kind of function that will display future values, this is possible using the security function in version 2 or the one in version 3 using barmerge.lookahead_on . The Use Of A Repainting Indicator Its always better to filter data in order to have a clearer view of what is happening, this can be useful when doing some forecasting or doing less formal kind of analysis. However since it repaint you cant use it as a signal provider or use signals of other indicators using this filter as source. For example if you want to forecast a smooth indicator, the forecast of this indicator under normal circumstances could still have lag associated with it, so you would have to react before your forecast, this wont happen if you apply this filter as your indicator source. The Filter We smooth with a simple moving average the price provided by the security function twice, length control the smoothing level. Since security depend on the time frame you are in you must select your time frame in the indicator parameter selection window. Filtering using 45 minutes time frame close price in a 5 minutes chart, we fix this by selecting our time frame. Consider the fact that the input of the indicator is just periodic price, so sometimes the lag can sometimes be less or more than 0 and the estimation not centered. The indicator can work on time frames up to 1h, after that the filter have some lag, i tried fixing this and i ended up having data errors. Applying our filter as source for the rsi oscillator. Conclusion It is possible to have a kind of zero-phase filters, but it would be better if pinescript could support backward indexing thus making us able to do forward backward filtering. Since noise can affect our analysis, applying smoothing without having to use offset in plot can be considered useful.
