Strategy doesn't open at breakout of bands but it waits for a pullback.
Upper and lower bands are used as resistance and support.
There are various parameters that can be optimized.
I have also a study with alerts.
Please use comment section for any feedback or cointact me if you need support.
Testing this on BANKNIFTY with 15min and higher timeframes. Strange view is the signal gives an short while the trades are all going in the other direction.
