this is my mod script for TV - Heikin Ashi RSI Oscillator.

Introducing HARSI - the RSI based Heikin Ashi candle oscillator.

...that's right, you read it correctly. This is Heikin Ashi candles in an oscillator
format derived from RSI calculations, aimed at smoothing out some of the
inherent noise seen with standard RSI indicators.

Updated - Added Stochastic, divergence, alert, minor code fix.

Not sure how accurate I have this. Trying to play with the isBull and isExp variables to make sure colors match. Had to add 4x AddChart()

Updated Image
hUqZ7kF.jpg


Version 1.1 of RSI_Div_Candles per @High_Velocity request.
(Thx @germanburrito for AddChart() logic)
Fixed/Added the following:
  1. Fixed hollow UP Candles - fix provided by @SleepyZ
  2. Adjusted OB/OS option to turn on/off
  3. Added Visual Divergence Lines - credit @SuryaKiranC

## V 1.1 :    @cos251 - @SleepyZ provided fix for hollow UP candles.  @SuryaKiranC provided Divergence line identifier
##                      Added option to turn on/off OB/OS lines.

UPPER STUDY VERSION 1.0 (per request from @TradeUp)
This is the upper version as requested (pretty lean on code too).
For now only includes the candle coloring, will have to work on plotting the Divergence Lines.

The indicator now works as expected. Thanks for your help. The next challenge is writing a scanner on 15 minutes. With the following
DOWN candle with Bull and not isExp
(this is signal is for short trades when the candle is bull and weak “pink color” with wick pointing down; print red dot or Red circle).
OR
UP candle with not Bull and isExp
(this signal is for long trades when the candle is bear and weak “pink color” with wick pointing up; print Green dot or Green circle).

OK, I like this indicator now that I've looked at it more.
It pairs nice with vol RoC

Updated colors to be more uniform

Thank you for your comment - this doesn't seem to do what the TV HARSI does - IMO - as the TV Harsi has zones to easily see when to go Long or Short - that is too simplistic of course - but it is Backtesting pretty well on TV

Try this. I wanted to test doing AddChart again so I took a stab at this one as well. I did not include the RSI histogram or the Stochastic plot. Both were unnecessary. Feel free to add if you like.

Folks - my humble suggestion is to use the HA RSI for trend following trades rather than for reversals.
Try to keep the candles without the smoothening setting. Look to go long when the candles cross the zero line from below and the opposite for shorts...you may add a macd histogram (with an 8/13/21 setting) or another indicator for a double confirmation..

Trying to finding the bottom and trade reversals using this indicator or any other for that matter is a trade that
looks tempting and simple, but is not worth it!!
 
Here's a scalping system using the RSI and the Heiken Ashi. It appears to have combined the code of both, but doesn't have buy/sell signals. Has anyone seen something like this in this forum? Take a look at this YouTube video.

HARSHI Chart Video
 
@Picard I have not seen this in thinkscript. It is available on Tradingview pinescript. Thanks for the link, I think it has merit, I'm going to strategize it on Tradingview, its too much to convert to TOS. I have realized you don't have to think in terms of one platform anymore when you can work with several and even interlink strategies and trading platforms. Actually I have found some studies just do better in certain platforms.

I moved your post to this thread. You will find a few variations of the RSI, Heiken.
Start here: https://usethinkscript.com/threads/rsi-heiken-ashi-for-thinkorswim.7250/#post-70605 and read your way through.

Would it be possible to Add option to turn on/off the Candles to just have the #Divergence? or just have the Divergence in upper on Price?
