Hi Dhan Team,
I see a nice feature “Calculate Divergence” in RSI indicator of tradingview, where it marks the Bull or Bear Divergence automatically on the indicator itself. I don’t see that feature in RSI indicator of Dhan TV. Though there is a separate RSI Divergence indicator but that is not having similar feature. Can you please add this feature in the main RSI Indicator?
I’ve given example screenshot from tradingview (free subscription only) .
Here is the pine script source code
