I have just started to learn trading in Options and hence looking at the Option Chain data on NSE site.
I need some clarifications for below pointers - Pls help
As we say, if OI is going up and Premium is going up then it is a Bullish sign, but even though this is happening on the NSE Option Data for most of the Out of money strike prices, experts say "huge CALL WRITING is happening at those Out of money Strike prices. So the underlying asset has a huge resistance etc.
1 - so the OI and Premium prices displayed under CALL section on NSE Option page - are they all only the CALL SELL position ? or they are mixed of CALL Sellers and CALL buyers ? If they are mixed of Sellers and Buyers then why people say there is huge CALL WRITING happening ?
2 - Similarly on the right side of the page, PUT data is shown. So are all the PUT Sellers OI and Premium data ?
