Nifty 15700 Put holds an Highest Open Interest Followed by 15500 & 15600 – which indicates an support near 15650 odd levels & on other hand 15900 & 16000 Call Holds an Highest Open Interest which indicates upside is capped near 15950 – 16000 level, observing the cues from option data we can interpret Nifty should expire in the range of 15650 to 15950 & hence we recommend Nifty Ratio Spread.

Where we suggest to buy ATM call option 15700 1 lot & sell OTM 15850 call Option 2 lot ( additional 1 lot of selling is to reduce the buy premium since it is OTM and if nifty doesn’t close above 15850 time value will erode eventually helping to reduce the buy premium by selling 1 extra leg)
