Hello Fellow Traders, Can some body help with the following queries: 1. How do you calculate daily IV of nifty options? I use the average of ATM Put/ Calls IV but its only an approximation... 2. I have come across several therads where members like AW10 Sir,Aditya14. SH10, Sir etc say current Nifty IV is high/low.Would be greatful if somebody could explain how to rate the current IV compared to historic IV.Can somebody provide a 24 month nifty daily IV data like they do for US stocks? 3. How correct is it to use VIX close data as a proxy for IV? 4. Finally many experienced traders i have met downplay the role of IV as theoritical rheoteric confined to the annals of PHD paperwork.They say that chart patterns are the best way to play options on nifty practically as IV can be low/hi but can remain there way beyond the option expiry.Can experienced traders share their views on this.. Will be immensely helpful..
