Sometime back a guy observed in Nifty →
- Nifty(underlying) is INCREASING.
- Both CALL and PUT Strikes are slightly OTM.
- Even if Nifty is moving in upward direction CALL premium is falling and PUT premium is increasing.
Both belong to the same expiry series. Volatility is same for both. Now when underlying is increasing then what could be the reason for CE falling while PE increasing ?
