Short Straddle
Range-bound, high conviction
Sell the ATM call and ATM put together. It collects the richest premium on the chain, at the cost of theoretically open-ended risk on both sides.

How it's built
Sell one ATM call and one ATM put, same strike, same expiry. Pure premium collection, no protective wings. The two premiums received are the most this trade can ever make.
When to deploy it
High conviction that spot pins near the current level into expiry: a quiet consolidation session, the kind DeltaK's own Protocol Delta reads as a Volatility Trap regime. This is an income strategy, not a directional one, and it needs active risk management, not a set-and-forget ticket.
Worked example
Say NIFTY is trading around 25,000 with a few sessions left before expiry. You sell the 25000 call for ₹109, and you sell the 25000 put for ₹109 — a net credit of ₹16,276 for one lot of 75.
At expiry, the position is worth the most once NIFTY is on the right side of 24783 or 25217 — up to ₹16,276 per lot. Move against that line instead and the worst case is capped at an open-ended loss that grows the further it moves against you, not open-ended.
Mistakes that break this strategy
- Running this uncapped through an event week. The same binary catalysts a long straddle is built for are what blows up a short one.
- Treating available margin as margin that should be used. Undefined risk on both sides means position size has to stay conservative regardless of what the exchange allows.
- No hard stop-loss on either leg. This strategy's appeal, the rich premium, is exactly proportional to the risk of an unhedged move through either breakeven.
