from 75 to 50 and now 25, nifty lot size reduced so much. is it an uncertainty or? reducing lot sizes also reduces the required capital for option selling, by this retailer can participate in option selling, which is good but, after witnessing Sensex, bankex and midcap options premium pluming. like rocket 
in expiries it scares me more and with a daily expiry makes retailers tempt to do option selling every day, if they can’t manage it properly it erodes all their yearly profits in a snap. so please be careful option sellers please dont do option selling in sensex, bankex, midcap,niftyfin. money control
