Sentiment Estimator [AstrideUnicorn]Sentiment Estimator is an indicator that estimates market sentiment using only its pricing data. It counts bullish and bearish candles in a rolling window and calculates their relative values as percentages of the total amount of candles in the window. Market sentiment shows the direction in which the market is biased to move or the current trend direction. Extreme values of the market sentiment are contrarian signals. When the market sentiment is too bullish, it is time to sell and vice versa.
HOW TO USE
Sentiment Estimator plots a pair of green and red circles for each candle. They represent bullish and bearish sentiments, respectively.
The vertical positions of the circles show corresponding sentiment values in percentage units. For example, if a green circle's height is 60, the market is 60% bullish. In this case, the red circle's height will be 40, as bullish and bearish parts of the market sentiment sum to 100%.
The blue line plotted at the 50% level shows the neutral sentiment level. If a green circle is above the blue line, the prevailing market sentiment at that time is bullish, and the market is biased to move up. If a red one is above, the market has predominantly bearish sentiment and is prone to move down.
The red level shows extreme sentiment level. If a green or red circle is above this line, it means that the market is extremely bullish or bearish, respectively. It is a contrarian signal, and one can expect a reversal soon. In this case, a blue label with the text "reversal expected" is shown.
SETTINGS
Timeframe - allows choosing a timeframe other than the chart's one for the indicator calculation.
Look-Back Window - sets the historical window length used to perform the calculations. You can adjust the window to get the best results for a particular market or timeframe.

Directional Movement w/Hann Slope Change SignalModified version of
Presented here is code for the "Directional Movement w/Hann" indicator originally conceived by John Ehlers. The code is also published in the December 2021 issue of Trader's Tips by Technical Analysis of Stocks & Commodities (TASC) magazine.
John Ehlers is continuing to revamp old indictors with Hann windowing. The original script uses zero line cross to signal buy/sell in this modified version buy/sell is signaled based on slope change, where signal is generated on with previous value is greater/less than current value
If current > previous = buy and if current < previous = sell
EneX SignalEneX is signal that give recommendation signals for entry and exit on spot market. This indicators not suitable for leverage trading in futures market.
EneX signal consider several indicators and has entry and exit rules.
EneX signal is suitable for investors who believe in trend following strategy (disclaimer on).

BBW EMA RIBBON+BB%B+EMA BUY/SELL SignalsBINANCE:BTCUSDT
* * * TESTED ON BTCUSDT 4H CHART * * *
The indicator gives signals based on possible ENTRY/EXIT zones (calculated using an ema ribbon of the BBW) and BB%B oversold/overbought conditions, also a 200 EMA filter is used to trade following the major trend.
ENTRY/EXIT zones can be used as a confirmation on other strategies (green zones suggest a possible entry for a long in an uptrend and for a short in a downtrend, red zones suggest a possible exit for long & short)
Only LONG signals are given.
Signals are divided in 3 categories based on their strenght:
- Weak BUY/SELL (green/red circles on chart)
- normal BUY/SELL (green/red triangles with "BUY" or "SELL" text on chart)
- strong BUY/SELL (green/red labels with "STRONG BUY" or "STRONG SELL" text on chart)
You can use signals from the same category as triggers for entering or exiting a trade or you can try using signals from different categories
All indicators settings can be costumized
Possible EXTRY/EXIT zones can be turned ON/OFF
Every signal label can be turned ON/OFF
EMA that changes color based on last candle close can be turned ON/OFF
Alerts can be set for:
- General Signals (every signal will trigger it)
- Weak Signals (only weak signals will trigger it)
- Normal Signals (only normal signals will trigger it)
- Strong Signals (only strong signals will trigger it)
There are 3 BB%B Oversold & 3 BB%B Overbought value presets:
- BASIC (default values)
- LOW (slightly lower values from default)
- HIGH (slightly higher values from default)
Tips:
Use BB%B OS LOW preset to find entries at a better price
Use BB%B OS HIGH preset to find entries faster
Use BB%B OB LOW preset to find exits faster
Use BB%B OB HIGH preset to find exits at a better price
There are 3 Filters already included:
- A checkbox to toggle ON/OFF the use of Heikin Ashi candels to detect trades
- A checkbox to toggle ON/OFF the use of an ema filter for the ribbon that tries to reduce the number of false signals on over-extended price movements
- A checkbox to toggle ON/OFF the use of an ema filter that tries to reduce the number of false signals when price crosses the moving average many times consecutively
FFTLibraryLibrary "FFTLibrary" contains a function for performing Fast Fourier Transform (FFT) along with a few helper functions. In general, FFT is defined for complex inputs and outputs. The real and imaginary parts of formally complex data are treated as separate arrays (denoted as x and y). For real-valued data, the array of imaginary parts should be filled with zeros.
FFT function
fft(x, y, dir) : Computes the one-dimensional discrete Fourier transform using an in-place complex-to-complex FFT algorithm . Note: The transform also produces a mirror copy of the frequency components, which correspond to the signal's negative frequencies.
Parameters:
x : float array, real part of the data, array size must be a power of 2
y : float array, imaginary part of the data, array size must be the same as x ; for real-valued input, y must be an array of zeros
dir : string, options = , defines the direction of the transform: forward" (time-to-frequency) or inverse (frequency-to-time)
Returns: x, y : tuple (float array, float array), real and imaginary parts of the transformed data (original x and y are changed on output)
Helper functions
fftPower(x, y) : Helper function that computes the power of each frequency component (in other words, Fourier amplitudes squared).
Parameters:
x : float array, real part of the Fourier amplitudes
y : float array, imaginary part of the Fourier amplitudes
Returns: power : float array of the same length as x and y , Fourier amplitudes squared
fftFreq(N) : Helper function that returns the FFT sample frequencies defined in cycles per timeframe unit. For example, if the timeframe is 5m, the frequencies are in cycles/(5 minutes).
Parameters:
N : int, window length (number of points in the transformed dataset)
Returns: freq : float array of N, contains the sample frequencies (with zero at the start).

+ JMA KDJ with RSI OB/OS SignalsSo, what is the KDJ indicator? If you're familiar with the Stochastic, then you'll know that the two oscillating lines are called the 'K' and 'D' lines. Now you know that this is some sort of implementation of the Stochastic. But, then, what is the J? The 'J' is simply the measure of convergence/divergence of the 'K' and 'D' lines, and the 'J' crossing the 'K' and 'D' lines is representational of the 'K' and 'D' lines themselves crossing. Is this an improvement over simply using the Stochastic as it is? Beats me. I don't use the Stochastic. I stumbled upon the KDJ while surfing around the web, and it sounded cool, so I thought I'd look at it. I do like it a bit more as the 'J' line being far overextended from the other two (usually into overbought/sold territory) does give a clear visual representation of the divergence of the 'K' and 'D' lines, which you might not notice otherwise. So, from that perspective I suppose it is nicer.
But let's get to the good stuff now, shall we? What did I do here?
Well, first thing you're wondering is why there are only two lines when based on my explanation (or your previous experience with the indicator) there should be three. I found this script here on TV, by x4random, who took the 'K' and 'D' lines and made an average of them, so there is only one line instead of the two. So, fewer lines on the indicator, but still the same usefulness. It was in older TV code, so I took it to version4 and cleaned up the code slightly. His indicator included the RSI ob/os plots, and I thought this was neat (even though the RSI being os/ob doesn't tell you much except that the trend is strong, and you should be buying pullback or selling rallies) so I kept them in. His indicator was also the most visually appealing one that I saw on here, so that attracted me too. Credit to x4random for the indicator, though.
Aside from code cleanup and adding the usual bells and whistles (which I will get to) the big thing I did here was change is RMA that he was using for the 'K' and 'D' lines to a Jurik MA's, which smooth a lot of the noise of other moving averages while maintaining responsiveness. This eliminates noise (false signals) while keeping the signals of significance. It took me a while to figure out how to substitute the JMA for the RMA, but thanks to QuantTherapy's "Jurik PPO" indicator I was able to nail down the implementation. One thing you might notice is that there is no input to change signal length. I fiddled with this for a time before sticking to using the period, instead of the signal (thus eliminating the use of the signal input altogether), length to generate the 'K' and 'D' calculations. To make any adjustments other than the period length use the Jurik Power input. You can use the phase input as well, but it has much less of an effect.
Everything else I changed is pretty much cosmetic.
Candle coloring with the option to color candles based on either the 'J' line or the 'KD' line.
color.from_gradients with color inputs to make it beautiful (this is probably my best looking indicator, imo)
plots for when crosses occur (really wish there was a way to plot these over candlesticks! If anyone has any suggestions I'd love to see!)
I think that's about it. Alerts of course.
Enjoy!
Below is a comparison chart of my JMA implementation to the original RMA script.
You can see how much smoother the JMA version is. Both of these had the default period of 55 set, and the JMA version is using the default settings, while the original version is using a length of 3 for the signal line.
Light BalanceThe script is simple, going for a color scheme logic which tenderly avoids rigorous signals processing.
For the script to remain simple, logical derivatives are also out; as such, there are no secondary relations built off of primary ones. And it also ignores (unless you do this yourself) the logic in a varying order of lines.
Coloring has been done according to a limited set of relations between the four (4) plotted lines.
Quite a bit of information is capture, as you'll see when looking at line order, crossings, and transparency transitions and their patterns.
The approach makes the relations ones which can be learned over time; you become the algorithm to sort out signals. Ha ha. I know that sounds like a cop out doesn't it. Did I mention it's a simple script?
One thing you might want to play with right away are fills having red and green, and lime and fuchsia. It would be cool to reduce it all down to two (2) colors, but all the boolean relations might have to be listed, and it also may not be possible to cumulatively combine transparency overlays of the same value. Visually, that approach may not result to awaken a useful feature anyway. Also, fill() has its limitations in that it cannot be in a local scope; this includes function wrapped calls to fill(), or calls made using branching logic statements if/elseif, iff(), and var = (cond) ? t_val/exp : f_val/exp. So, to my knowledge, a fill() can not be made to be logically on/off.
Please, enjoy getting some use out of it.
Multi-timeframe MAs + Stoch RSI SignalsHello traders,
I welcome you to my first published script on TradingView: “Multi-timeframe Moving Averages + Stochastic RSI”.
The script is based on a simple formula: Buy signals are generated when a fast moving average is above a slower moving average (uptrend) and the Stochastic RSI K line is crossing above the oversold level (entry).
Sell signals are generated when a fast moving average is below a slower moving average (downtrend) and the Stochastic RSI K line is crossing below the overbought level (entry).
This indicator works best in strong trends!
**Please note the above example has repainting turned on which may produce unrealistic results when viewing historical data. See below for more information regarding this and how you can turn it off.**
The user has the following inputs:
- Option to change the Stochastic RSI settings, including the oversold and overbought levels.
- Option to enter any value for both the Fast Moving Average and the Slow Moving Average.
- Option to change between EMA or SMA for each moving average.
- Multiple time frames to choose from, as well as the ability to selectively turn off individual time frames (both plots and alerts).
(Default time frames are 1 hour, 4 hour, and Daily. You can have a 4th time frame by changing your current time frame to something lower than the other 3 time frames)
- Turn on/off repainting: If repainting is turned on you will get an alert and buy/sell signal on chart immediately when condition is met, however the signal may disappear from chart if the condition reverses during the same candle.
If repainting is turned off, the indicator will wait for the candle to close before issuing the alert and painting the signal on chart.
For higher time frames, the indicator will wait for the candle in the higher time frame to close before issuing a signal if repaint is turned off. Default is set to Repaint on, so please be aware of this if you do not want repainting.
How to use alerts:
- Before you do anything, make sure your current time frame is the lowest time frame you’d like alerts on, as you will still receive alerts for the higher time frames you selected in settings.
- Once you have all the settings changed to how you like, save your chart first. Then right click on any of the indicator’s buy/sell signals on the chart and click “Add Alert on MAs + Stoch RSI”.
- Make sure “Any alert() function call” is selected under the Condition.
- You can delete or change the text in “Alert name” if you want as the alert message is already built into the indicator, and it will tell you in the alert message which asset and time frame to buy or sell.
Other things to note:
- The indicator will not display the buy/sell signals of lower time frames when you are on a higher time frame. This was done purposely to reduce clutter on the chart when you switch to higher time frames.
- While the alert message will tell you which time frame a signal was generated, the plots on the chart will instead show “Buy/Sell TF1, or TF2, or TF3”.
If the signal is from the current time frame that the alert was created on, then it will simply show “Buy” or “Sell”.
Hope you guys enjoy using this one, please drop a like if you found it useful. If anyone wants to modify my script in any way, please just credit me for the original work when you publish the script. Good luck!
[GJ]IFRSITHE INVERSE FISHER TRANSFORM STOCH RSI
HOW IT WORKS
This indicator uses the inverse fisher transform on the stoch RSI for clear buying and selling signals. The stoch rsi is used to limit it in the range of 0 and 100. We subtract 50 from this to get it into the range of -50 to +50 and multiply by .1 to get it in the range of -5 to +5. We then use the 9 period weighted MA to remove some "random" trade signals before we finally use the inverse fisher transform to get the output between -1 and +1
HOW TO USE
Buy when the indicator crosses over –0.5 or crosses over +0.5 if it has not previously crossed over –0.5.
Sell when the indicator crosses under +0.5 or crosses under –0.5 if it has not previously crossed under +0.5.
We can see multiple examples of good buy and sell signals from this indicator on the attached chart for QCOM. Let me know if you have any suggestions or thoughts!
Moving Average Crossover with Shading Signals This script uses 3 moving averages (2 simple moving averages and 1 exponential moving average ) to signal long and short opportunities based on moving average crossovers.
A long SMA (Signal SMA2) is used to determine longer term trend. When the EMA crosses above the Slow SMA1 and price is above the Signal SMA2. The space between the moving averages will shade green and the Signal SMA should also be green.
A sell signal occurs when the EMA crosses below the Slow SMA1 and price is below the Signal SMA2. The space between the moving averages will turn red and the Signal SMA should also be red.
A retracement, consolidation, or reversal may be occurring if the shaded color is yellow.
Use the identifying shapes to learn when to open or close positions.
Jaws Mean Reversion [Strategy]This very simple strategy is an implementation of PJ Sutherlands' Jaws Mean reversion algorithm. It simply buys when a small moving average period (e.g. 2) is below
a longer moving average period (e.g. 5) by a certain percentage and closes when the small period average crosses over the longer moving average.
If you are going to use this, you may wish to apply this to a range of investment assets using a screener for setups, as the amount signals are low. Alternatively, you may wish to tweak the settings to provide more signals.

OptionsMillionaire SPY Moving Averages and Signalsby ColeJustice
OptionsMillionaire's SPY Options trading system is based mainly on these indicators:
- 8 EMA*
- 21 EMA*
- 100 SMA*
- 200 SMA*
- MACD
- RSI
- Squeeze Momentum
(*provided by this indicator)
and follows these rules:
|
| 1) I never fight the trend. If its green, i buy calls. If its red, i buy puts. I will only buy puts on a green day if there is a overall change in market trend. Inversely, calls on a red day
| 2) Price action is my #1 indicator. I wait for it to confirm my thesis before i enter a trade
| 3) I only trade SPY Options
| 4) My baseline is to choose a call/put that has a DTE (Date To Expiration) 6-7 days out, with a strike $2-$3 away. I adjust that to fit my current appetite for volatility. i virtually never play same day DTE's.
| 5) I set a 10% stop, but usually exit at 8% before my stop triggers depending on current situation
| 6) I utilize about 10-20% of my Portfolio for one trade. Sometimes more. Rarely less.
| 7) I never hold overnight in these market conditions.
| 8) I shoot for 10-20% for gains. Depending on market conditions.
| 9) Always look for confirmations in your indicators.
| 10) I never force a trade. No trade is a good trade too if the entry just isn't there.
| 11) Patience always pays off. A great set-up can form in minutes or seconds. I never regret being patient to enter. I nearly always regret rushing into a trade.
|
This indicator combines the moving averages into a single unit to simplify one part of the indicator usage rules: the 8 EMA / 21 EMA Cross. . The 8 crossing over the 21 is a Bullish signal, while the 8 crossing under the 21 is a Bearish signal. This indicator places flags at these crossover/under points, as well as shading the area between the 8 and 21 EMAs to help visualize the strength of the trend; green during a Bullish cross, and red during a Bearish cross.
A new addition to this strategy is the Hull Moving Average, or HMA. This script defaults to an HMA of 20 and shows alerts when candles close above or below the plot in the form of green and red candle backgrounds. This alert is best used in conjunction with the main crossovers and should be considered an addition level of confidence rather than providing trade entry/exits directly. This indicator is more flexible and you should feel free to adjust the period if you find a different value works better within your own personal trading style.
Each individual element of this indicator can be modified or toggled, providing maximum customization. While you should strive to become comfortable with the default settings, these options are provided in case you feel the need to adjust for your own style (or if testing on tickers other than SPY, for example).
Goodluch, and happy trading!
The Bayesian Q OscillatorFirst of all the biggest thanks to @tista and @KivancOzbilgic for publishing their open source public indicators Bayesian BBSMA + nQQE Oscillator. And a mighty round of applause for @MarkBench for once again being my superhero pinescript guy that puts these awesome combination Ideas and ES stradegies in my head together. Now let me go ahead and explain what we have here.
I am gonna call it the Bayesian Q Oscillator I suppose. The goal of the script is to solve an issue both indicators on their own suffer from. QQE signals are not new and often the problem has always been false signals for them. They are good for scalping but the difference between a quality move and a small to nearly nonexistent move following a signal is not so clear. Kivanc made his normalized version to help reduce this problem by adding colors to his histogram type verision that would essentially represent if price was a trending move or in a ranging structure. As you can see I have kept this Idea but instead opted for lines as the oscillator. two yellow line (default color) is a ranging sideways area and when there is red or green it is trending up or down. I wanted to take this to the next level with combining the Bayesian probability oscillator that tista put together.
The Bayesian indicator is the opposite for its issue as it is a probability indicator that shows which candle or price movement is more likely to come next. Red rising means possibly down move soon and green means up soon. I will not go into the complex details of this indicator but will suggest others take a look at his and others to understand the idea behind them. The point I am driving at is that it show probabilities or likelyhood without the most effecient signal device to match it. This original was line form and now it is background filled colors.
The idea. is that you can potentially get some stronger and more accurate reversal signals with these two paired together. when you see a sell signal or cross with the towering or rising red... maybe it is a good jump potentially. The same for green. At the same time it is a double added filter effect from just having yellow represent it is ranging... but now if you get a buy signal (example) and have yellow lines (example) along wi5h a red rising or mountain color background... it not only is an indication of ranging, but also that there is potentially even a counter move coming based on the probabilities. Also if you get into a good trade and see dual yellow qqe crosses with no color represented by the bayesian background... it is possible it might only be noise.
I have found them to work decently in the 1 hour timframe. Let me know your experience.
I hope everyone takes a look at the originals to understand them. Full credit goes to those guys for this to be here. Let me know how it is working out for you.

Local Limit AlignmentCombines the trends of multiple local limits to provide a signal that represents how strongly they are aligned.
Each local limit has a value of either +1 or -1. The sum of all depths provides a signal.
The defaults are a minimum depth of 2 and a maximum of 4 resulting in upper and lower values between -3 and +3, and a total between -6 and +6.
EMA Cross and MACD Signal CombinedThe rule is simple.
When MACD crosses up, it is supposed to give a buy signal. However, before entering into a Long position, there is a need for a confirmation. This confirmation can be from a down trendline breakout or from another indicator.
In this case, I've chosen the Exponential Moving Average Cross to be as the confirmation.
The Buy Signal will appear when there it fulfills the following conditions:-
i. The MACD line is above the Signal Line
ii. The fast EMA crosses the Slow EMA
The Sell signal will appears when the opposite of the above condition is met.
This indicator is meant for the Swing Trader whom would like to hold a position for a long time.

[blackcat] L2 Ehlers Signal to Noise IndicatorLevel: 2
Background
John F. Ehlers introuced Signal to Noise Indicator in his "Rocket Science for Traders" chapter 8. Dr. Ehlers terms the case where half the average daily trading range is equal to the signal amplitude as our zero decibel Signal-to-Noise Ratio (0 dB SNR) condition. He wants the signal amplitude to be at least twice the noise amplitude (6dB SNR) so that there exists a reasonable chance to make a profit from the chart analysis.
Function
blackcat L2 Ehlers Signal to Noise Indicator is used to measure Signal-to-Noise Ratio (SNR). The SNR in decibels is calculated in a single line of code near the end. The signal power is divided by the noise power to get a power ratio. The logarithm of the power ratio. At 0 dB, the peak-to-peak noise signal is twice the amplitude of the signal. Therefore, when we compute the 0 dB case, the ratio is calculated to be 10*log(1/2)^2 = -6 dB. We must then add 6 dB back into the computation to remove this bias, establishing the definition of 0 dB SNR.
Key Signal
Smooth --> 4 bar WMA w/ 1 bar lag
Detrender --> The amplitude response of a minimum-length HT can be improved by adjusting the filter coefficients by
trial and error. HT does not allow DC component at zero frequency for transformation. So, Detrender is used to remove DC component/ trend component.
Q1 --> Quadrature phase signal
I1 --> In-phase signal
Period --> Dominant Cycle in bars
SNR --> Signal-to-Noise Ratio
Pros and Cons
100% John F. Ehlers definition translation of original work, even variable names are the same. This help readers who would like to use pine to read his book. If you had read his works, then you will be quite familiar with my code style.

Readme
In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.
The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.
Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.
Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.
Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated.
Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.
Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.
XAGUSD Long/Short Signal ~ By: Sarp GokdagAbout the Oscillator :
The Rex Oscillator is a study that measures market behavior based on the relationship of the close to the open, high and low values of the same bar. The theory behind the Rex Oscillator is that a big difference between the high and close on a bar indicates weakness. Conversely, wide disparity between the low and close indicates strength. The difference between open and close also indicates market performance.
The True Value of a Bar (TVB) gives us an indication of how healthy the market is. It is possible to have a negative close and a positive TVB, and vice versa. This indicates that the market is building strength on the opposing side of the trend. The Rex Oscillator is a moving average of the TVB, indicating the inertia of the market. When the Rex Oscillator turns positive in a bearish trend, a reversal is indicated. Likewise, Rex turning negative in a bull market indicates a reversal to the downside.
When the Rex Oscillator turns positive in a bearish trend, a reversal is indicated. Likewise, Rex turning negative in a bull market indicates a reversal to the downside.
The REX Strategy goes long when the REX line of the REX Oscillator crosses above the Signal line and Short when the REX line crosses below the Signal line. The strategy is a reversal strategy through the use of the 'Cover and go Long' and 'Close and go Short' Actions. The REX Oscillator properties of Period' and Signal' can be changed for testing purposes using the available Rex1 'Factor.'
The blue line indicates the difference between the Rex MA and the Signal.
If the blue line crosses above "0", go Long.

Internal Bar Strength IndicatorThe Internal Bar Strength Indicator is pretty basic but very intuitive. Most stocks that close near their high of the day tend to fall the next day and stocks that close near their low tend to rise the next day. This indicator has very similar buy and sell signals as the RSI. Buy when the indicator rises above its signal or if the indicator is in the red zone and rises up outside of the red zone. Sell when the indicator falls below its signal or if the indicator is in the green zone and falls down outside of the green zone.
