I am trying to find a RSI divergence setup that works in combinations with ma, chart pattern , SR Levlels etc - not sure yet which combinations works best but thats why i am looking to code the first step in pine script to help me with backtesting.
The basic idea is to take the following divergence setup as the base for further analysis:
https://imgbox.com/HjmTJ3Ly
Rules for this setup:
1. This setup is reversal only so no need to plot hidden divergences
2. Between point A and B is a divergence and between point B and C is a divergence and between A and C is also a divergence
3. Very Important
3.1: on Price: point B is below A, and C is below A and B (only close price)
3.2: on RSI: point B is above A, and C is above A and B (meaning if point C is between A and B than the setup is invalid even if 3.1 is valid)
3.3: on Price: Furthermore setup is only valid if a candle closes above point A after point C has formed
4. It should be possible to configure within how many bars this setup should occur (point A to point D)
I would take the following public script: https://www.tradingview.com/script/CaMo ... e-Pine-v4/ by kingthies since this should have most of what I need. I think whats missing is to "only" include checks for point C and D.
I dont mind coding it myself but I need some pointers - I appreciate any help you can give me.
Thanks,
Don
