Why Strike Price Selection Is Crucial in Bank Nifty
Bank Nifty is known for sharp moves and strong intraday volatility. Because of this:
Premiums move faster

That is why structured strike selection is more important here than in slower indices.

Bank Nifty rewards momentum trades. But probability still matters more than excitement.
