RecursiveAlertsLibrary "RecursiveAlerts"
The library provides options to run alert() calls in loop without worrying about limitations of frequency options.
When an alert statement is called within a loop,
it will fire just once per bar irrespective of how many iterations allowed when fequency is set to alert.freq_once_per_bar or alert.freq_once_per_bar_close
it will fire continuously till it breaks when frequency is set to alert.freq_all
The function helps overcome this issue by using varip key array which resets on every bar
rAlert(message, key) Enhanced alert which can be used in loops
Parameters:
message : Alert message to be fired
key : Key to be checked to avoid repetitive alerts
Returns: array containing id of already fired alerts
Thanks to @theheirophant, @JohnBaron and @LucF for discussions and suggestion which eventually lead to this solution :)

Wolfe Scanner (Multi - zigzag) [HeWhoMustNotBeNamed]Before getting into the script, I would like to explain bit of history around this project. Wolfe was in the back of my mind for some time and I had several attempts so far.
🎯Initial Attempt
When I first developed harmonic patterns, I got many requests from users to develop script to automatically detect Wolfe formation. I thought it would be easy and started boasting everywhere that I am going to attempt this next. However I miserably failed that time and started realising it is not as simple as I thought it would be. I started with Wolfe in mind. But, ran into issues with loops. Soon figured out that finding and drawing wedge is more trickier. I decided will explore trendline first so that it can help find wedge better. Soon, the project turned into something else and resulted in Auto-TrendLines-HeWhoMustNotBeNamed and Wolfe left forgotten.
🎯Using predefined ratios
Wolfe also has predefined fib ratios which we can use to calculate the formation. But, upon initial development, it did not convince me that it matches visual inspection of Wolfe all the time. Hence, I decided to fall back on finding wedge first.
🎯 Further exploration in finding wedge
This attempt was not too bad. I did not try to jump into Wolfe and nor I bragged anywhere about attempting anything of this sort. My target this time was to find how to derive wedge. I knew then that if I manage to calculate wedge in efficient way, it can help further in finding Wolfe. While doing that, ended up deriving Wedge-and-Flag-Finder-Multi-zigzag - which is not a bad outcome. I got few reminders on Wolfe after this both in comments and in PM.
🎯You never fail until you stop trying!!
After 2 back to back hectic 50hr work weeks + other commitments, I thought I will spend some time on this. Took less than half weekend and here we are. I was surprised how much little time it took in this attempt. But, the plan was running in my subconscious for several weeks or even months. Last two days were just putting these plans into an action.
Now, let's discuss about the script.
🎲 Wolfe Concept
Wolfe concept is simple. Whenever a wedge is formed, draw a line joining pivot 1 and 4 as shown in the chart below:
Converging trendline forms the stop loss whereas line joining pivots 1 and 4 form the profit taking points.
🎲 Settings
Settings are pretty straightforward. Explained in the chart below.
Just Another RSIThis is slightly different implementation of RSI using arrays. But, it also comes with a twist.
Formula for standard RSI can be found here: www.investopedia.com
If there is green candle, gain for the candle is equal to price movement from previous bar and loss for that candle is 0. Similarly in case of red candle, loss is considered to be movement from previous candle whereas gain is 0. Also, as mentioned in step2, on each bar, average of previous bar gains/losses are merged with present candle gain/loss.
New Process
Gain is considered only on green candles. Hence, there is no zero gain candles
Loss is considered only on red candles. Hence, there is no zero loss candles
Average or median of last N gains and losses are considered. Hence, the movement mainly tell us the strength between bullish and bearish candles.
Let us forget about seeing it as overbought and oversold area and look at it as bullish and bearish region.
How it is different
Since, gain and loss are only considered if there are gain and loss, this index represents the strength between bullish and bearish candles without looking at price movement. Hence, the index has capability to go in opposite direction of the price representing price movement is not supported by strength.
Another advantage of this implementation is it allows using variable length for the method. In case of RSI, length has to be constant. It cannot be variable which can change every bar. But, we do not have that constraint in this implementation due to use of arrays.
At present, this is purely experimental. I will look forward to study this more with respect to divergence and for use in trend following methods.
Zigzag MatrixNothing fancy. Just converted the new matrix library of zigzags ( mZigzag ) into indicator as I sensed it can be useful as indicator.
On top of the standard zigzag, the indicator also tracks given oscillators, moving average and volume indicators on each pivots. More indicators can be added programmatically - but it will take up space in chart. Hence, so far I have only added option to add one per each type (moving average, oscillator and volume)
Settings are as below

Wedge and Flag Finder (Multi - zigzag)Here is a small attempt to automatically identify wedges and flags.
Tradingview standard wedge checks for only 4 pivots. In this version, I have considered 5 pivots instead - which can help reduce noise as 4 pivots forming wedge can be quite common. In future, will also try to add more pivots in pattern recognition to make the signal more accurate.
If wedge comes with a tail, then it is marked as flag :)
Settings are quite simple and they are as shown below

Zigzag Volume BarsBack to my favourite topic - Zigzags.
Here is an indicator which can help you visualise volume data on Zigzag swing highs and lows.
Settings are pretty simple and provides variety of display options
Display options are as demonstrated in the chart has following main types.
Regular
Plus/Minus - Stacked
Plus/Minus - Overlapping
Plus/Minus - Opposite Sides
Apart from the main display types, stacked display has several sub-types which determine whether to place green bar below red or the other way around.
Snapshot below shows example of each type.
Volatility/Volume ImpactWe often hear statements such as follow the big volume to project possible price movements. Or low volatility is good for trend. How much of it is statistically right for different markets. I wrote this small script to study the impact of Volatility and Volume on price movements.
Concept is as below:
Compare volume with a reference median value. You can also use moving average or other types for this comparison.
If volume is higher than median, increment positive value impact with change in close price. If volume is less than median, then increment negative value impact with change in close price.
With this we derive pvd and nvd which are measure of price change when volume is higher and lower respectively. pvd measures the price change when volume is higher than median whereas nvd measures price change when volume is lower than median.
Calculate correlation of pvd and nvd with close price to see what is impacting the price by higher extent.
Colors are applied to plots which have higher correlation to price movement. For example, if pvd has higher correlation to price movement, then pvd is coloured green whereas nvd is coloured silver. Similarly if nvd has higher correlation to price then nvd is coloured in red whereas pvd is coloured in silver.
Similar calculation also applied for volatility.
With this, you can observe how price change is correlated to high/low volume and volatility.
Let us see some examples on different markets.
Example 1: AMEX:SPY
From the chart snapshot below, it looks evident that SPY always thrive when there is low volatility and LOW VOLUME!!
Example 2: NASDAQ:TSLA
The picture will be different if you look at individual stocks. For Tesla, the price movement is more correlated to high volume (unlike SPY where low volume days define the trend)
Example 3: KUCOIN:BTCUSDT
Unlike stocks and indices, high volatility defined the trend for BTC for long time. It thrived when volatility is more. We can see that high volume is still major influencer in BTC price movements.
Settings are very simple and self explanatory.
Hint: You can also move the indicator to chart overlay for better visualisation of comparison with close price.
WVF - OscillatorAnother attempt on making use of CM-Williams-Vix-Fix-Finds-Market-Bottoms from Chris Moody - which is arguably one of the best indicator available on pine and tradingview platform. Every time I revisit this, I get new ideas on applying this method.
I have slightly altered formula to
highest(source)-source/highest(source)
from the original formula
highest(close)-low/highest(close)
Process is simple:
Calculate WVF for OHLC values separately
Calculate momentum on each of the WVF values based on distance from moving average
Plot the candles based on OHLC momentum.
Candle color depends on whether close, open and previous close. If close is higher than open and previous close, we get green coloured candles. If close is lower than previous close and open then we get red coloured candles. In all other cases, we will have silver candles.
High/Low bands are calculated based on median of highest and lowest values of VixFix. We also plot median of close which can be used in some cases.
How to use this to find market bottom. Look for one of the below conditions:
First red candle above high band - which signals momentum of vix fix is about to fall.
First red candle above median line - can be used only if upward momentum of wvf candles are trending well.
Crossunder of wvf candles under high band.
Possible exit scenarios
Green WVF candle formed above WVF high line
Entry is taken on first red candle above median line - but, candles turned green before WVF crossing under median line - may signal our thesis is wrong and price may drop further.
Some examples.
Intrabar OBV/PVTI got this idea from @fikira's script Intrabar-Price-Volume-Change-experimental
The indicator calculates OBV and PVT based on ticks. Since, the indicator relies on live ticks, it only starts execution after it is put on the charts. The script can be useful in analysing intraday buy and sell pressure. Details are color coded based on the values.
Data is presented in simple tabular format.
Formula for OBV and PVT can be found here:

Max drawdown daysA friendly reminder to myself and rest of the traders that market can stay low for prolonged time!!
Details are pretty simple.
Here is small comparison of the stats for major US indices.
Can also be applied to stocks. Cells are highlighted in red background ii
Drawdown/Recovery is still in progress for historical stats
Current drawdown bars/recovery bars are higher than that of median of All time stats.

Historical Range (Using eStrategy library)⬜ The script is intended to cover few things.
▶ Strategy testing framework based on eStrategy library
▶ Using historicalrange of values for identifying better entry and exits.
This is also built on top of the Systematic Investment Plan script published here
⬜ Strategy testing framework
Strategy testing framework is different from tradingview default strategy testing from few ways to suit the needs of systematic investments.
▶ Supports recurring investment on top of initial investment to emulate adding further funds to the investment bucket on regular basis.
▶ Better calculation of drawdowns based on daily equity rather than drawdown calculated only on close of trade.
▶ Provides better control over how much strategy can reduce and reload
Having said that, this framework is not intended as replacement for tradingview strategy framework. It is not as comprehensive as tradingview strategy framework. But, created to address few specific styles of strategy.
▶ No detailed trade stats on individual trades. But, this can be implemented in future versions
▶ At present only facilitates long positions.
▶ UI features such as plotting trades on chart are not available.
▶ Does not take into consideration of slippage and brokerage - this is not an issue because the framework is not meant for short term trades. It is only made for daily timeframes.
▶ No pyramiding or leverage possible.
And many more...
Framework can be used for similar strategies based on market timing with few small changes.
⬜ Historical Range Strategy
Concept here is, instead of taking indicators such as oscillators as is, use historical percentile to derive better oversold and overbought conditions. Strategy provides different options to base historical range. This can either be based on
▶ Band percent
▶ Oscillator
Different choices of bands and oscillators are also available to chose. However, have not done extensive testing on all the combinations.
⬜ Settings
▶ Initial and recurring investment settings (As confirm inputs)
▶ Buy and hold and strategy specific settings to be used for stat calculation
▶ Band and oscillator parameters
These are straightforward parameters which is used for defining the base of either bands or oscillators.
▶ Percentile moving average parameter
Percentile MA is used with Percentile to find entry and exit signals based on crossover and crossunder.
Feedbacks and suggestions welcome.

Systematic Investment PlanTradingview default strategy tester has few limitations. To name some:
Tradingview default strategy tester does not have option for periodic investment.
Does not allow reduce and refill kind of operations.
Comparison to buy and hold equity does not take into consideration on number of days invested
Hence, I created this as base for my further experiments with respect to strategies involving market timing.
Settings are quite simple and self explanatory.

Manual Harmonic Projections - With interactive inputsThis is another script involving interactive inputs. This is similar to Manual-Harmonic-Patterns-With-interactive-inputs . But, instead of taking XABCD and verifying if it confirms to any pattern, here we only take XABC and project all PRZs.
Example, upon adding the script to chart, it will prompt to select 4 points on chart by clicking on it. if we select X, A, B, C as shown in the chart below, we can see the projection of multiple PRZs. Mid of nearest PRZ is considered as D and rest of the pattern is drawn based on this. However, the pattern can have multiple PRZs. All overlapping PRZs are combined together and shown as one along with merged pattern labels. But, if there is gap between PRZs, they are shown separately.
If no projections found, then patterns and projections are not drawn. However, you can still see XABC lines on the chart.
Manual Harmonic Patterns - With interactive inputsThis script is a drawing tool which allows users to draw XABCD on the chart and script will tell whether there is any harmonic patterns on the drawings made. The script is based on interactive inputs and requires users to chose XABCD points.
Please note
This is not a scanner and it will not scan historical bars for harmonic patterns. This needs to be used rather as drawing tool instead.
Script will not check if selected pivots are correct. It assumes users to know how to select the right XABCD based on pivot high/lows. Bullish pattern will have X, B and D as pivot lows and A,C as pivot highs. Similarly bearish patterns will have X, B, D as pivot highs and A, C as pivot lows.
Script will not check for overflow conditions. For example, if price crosses, XB or BD line, then pattern is considered to be invalid. But, this check cannot be made in this script and we require users to be aware of this condition and select input accordingly.
Order of inputs should be in ascending order. X pivot should come before A and then, B, C, D and F. This again is users responsibility to select pivots in right order.
What happens after selecting XABCD?
If selected pattern is valid harmonic pattern, it will
Draw XABCD lines and labels
Fill harmonic triangles
Show PRZ box which shoes the name of valid patterns.
If it is not valid harmonic pattern, then users will see blank XABCD line without any PRZ or filled harmonic triangles.
Example:
1. When it is valid pattern
2. When it is not valid pattern

X-Mas TreeLet's play a game!! Find your Christmas Tree and post it in the comments.
How to use the script?
Open any instrument which best describes the Christmas Tree (Preferably on hourly timeframe).
Apply X-Mas Tree script on the chart.
Enjoy the snowfall, changes in lightings and other animations. Animations only happen if the instrument is in trading session. So, stocks and indexes do not work on weekends and holidays. Use crypto as they are traded 24X7.
Unfortunately cannot post moving charts. But, snapshot of chart will do :)
Well, Please don't ask these questions for this script (Also thanks to @Bjorgum for contributing to this section) 😃
Can you please add alerts?
Does it repaint?
Can we use this for crypto/stock/forex bla bla?
Can you convert this to strategy?
How can I access this indicator?
Can you please give access or how much does it cost?
Can you make it available for MTF?
Indicator is broken. Getting so and so error message etc.
Wish you all MERRY X-MAS and HAPPY NEW YEAR!!
Supertrend - Ladder ATRThis is a supertrend with slight twisted concept which can be very benefecial in strong trending markets to reduce stop loss distance and exit slightly quicker.
⬜ Concept
▶ When the instrument is trending up, regular ATR shows high values if there are big green candles. This affect the stoploss distance in regular supertrend which leads to wide stops or delayed lagging. When you are in long trade, what matters for stoploss is how much a negative candle can move within bar. Hence, using ATR derived only based on red candles is more beneficial for trailing stops on long signals. Same applies to short trades where using ATR derived from only green candles is more efficient than overall ATR.
▶ ATR will be minimal when the volatility is less and ATR will increase with volatility. That means, once you are in trade, the trailing of stoploss also will vary based on ATR (or volatility). With regular ATR and supertrend, chances of stop loss distance widening is high with increased volatility even though stoploss levels will not move down. This again poses the risk of higher drawdown during trade closure and also keeps in the trade during ranging market. To avoid this, the second trick we are using here is only to reduce the atr stoploss difference when in trade. That is, when in long trade and negative candles ATR is increasing, we will not consider that. We will consider the new ATR only if it is lesser than previous bar ATR.
Effect of these changes on the trending market is quite visual. Lets take example of USDTRY
Settings are quite simple and does not vary much from regular supertrend settings.
