How does one calculate option chain resistance?
*******
What I observe,
1. No of highest Oi in 5 strikes both PE and CE both Nifty and Bank Nifty every day EOD. And in market time too.
2. How Oi changes EOD.
3. Where is the max pain.
*******
Highest Oi strikes tries to act as option chain support and resistance many times and price tries to go near max pain during near to expiry.
But you can see the greater picture only when u analyse the strikes and compare it day to day basis EOD. You can see the greater picture when u can combine option chain with volumes, OI and prices of futures too (secret trick).
