Initially, you can keep a stop loss of 36200 & 37400 for this strategy. Means square off if you find banknifty is giving a breakout or breakdown. Or you can do this adjustment too.
If you find that BankNifty is giving a breakdown and sustaining below 36200, then square off the call spread and bring it down to 800 points lower levels.
The same thing you can do with put spread means if you got a breakout from 37400. You can shift your put spread to 800 points up.
