Quantitative Mechanics

How the Structure Works

Higher probability of profit (>75% win rate) than a straddle, but lower total premium collected.

A Short Strangle sells an Out-of-The-Money Call and an Out-of-The-Money Put far away from the current market price (e.g. 15-20 Delta). It gives a massive 800-1,000 point cushion in Nifty. You win as long as the market stays within your wide safety zone.

Short Strangle FAQs

What is the difference between a Straddle and a Strangle?

A Straddle sells ATM options at the same strike (higher premium, tighter breakevens). A Strangle sells OTM options at different strikes (lower premium, much wider safety margin).
