From last 19/07/2021 indusind bank range is 975 to 1045 it can’t sustain above 1045 for few days as it shows that is major resistance. So it will eat premium as one can short ITM call and buy OTM call. Example one can buy 1000ce and sell 980ce. As banknifty also showing weak data so it will be good strategy for this month expiry. Please do with proper risk management and proper sl. This is just a view for educational purpose.
