Not much to say by merely watching change in open interest here. But during the market hours, roughly at around 1 pm, i had noticed a huge , something like +455 K change in OI of 4300 PE and 4400 PE. Well, the nifty shed around 40 points after that. This vindicates my stand change in OI is also good for short term, or intraday predictions. I'll keep posting such observations (or even observations contradictory to this claim :) ) as i keep noticing them.

I dont know how to take clues from put calls in the last few days of F & O expiry. Maybe one should also peep into what is happening with the next month options to get a better picture in the last week of F&O expiry. Also since there is no significant change in OI i will spare myself the trouble of calculating implied volatility.
