Long Strangle on Bank Nifty: Wider, Cheaper, Further

A long strangle buys an OTM call and an OTM put. It costs less than a straddle (OTM premiums are cheaper) but needs a larger move to profit. Like the straddle, it is long volatility. The wider zone means more time/space for the move to pay, at the cost of a bigger required move.

Use when IV rank is low and a large Bank Nifty move is expected (earnings, event, or breakout with oi_buildup). The filter confirms iv_rv_spread and vix_z before entry. Avoid strangles after IV has spiked. Size by combined premium; both legs can expire worthless if the index stays pinned.
