Hi,
First of all we may see more volatility before FOMC event & final decision on Grexit.
Yesterday I observed large call writing @ 8100 , 8000 which were squared during last hour and market rallied by 80 pts ( from 8950).
Presently 7850,8000 puts do suggest some bullishness.
IMO 7800 is too far to hugely affect daily movement of the market just like 8500 calls ( which was - ve ). Btw now the longer term resistance have shifted to 8200 from 8500 yesterday.
Deep OTM options would have yielded +ve returns for this series by now and we may see profit taking time to time.
More reasons for us to write deep OTM options at the beginning of the series
