There might be teething issues and learning issues with the way NSE is conducting CAS but it would enormously help the market and its own credibility if NSE would analyze all the big participants in CAS and analyse their other trades during the day and confirm (formally and in black and white) that they do not see any attempt at manipulation by any market participant.
@dhirajsinha TBH I don't know the formula. But based on correlation of stock with nifty an indicative delta can be arrived. I heard on tastytrade they have it. Can be very useful to know what can happen to your portfolio with index movements.
@raahi_bhushan Keep hedges only for sustained nifty level. You will get them in monthlies or quarterlies. In our market near term hedges are very expensive.
