Short Strangle (Premium Selling)
Short VolBest regime: VIX 14-20 (normal to mildly elevated)
Sell an OTM call AND an OTM put, both expiring weekly. Collect rich time decay while NIFTY chops sideways.
Entry
Open on Monday or Tuesday after NIFTY has had two consecutive flat-to-down sessions. Avoid initiating on event days (RBI, Fed, Budget).
Strike Selection
Sell strikes with delta 0.15-0.20 on each side (roughly 1.5-2% OTM from spot). The combined premium should be at least 1.2% of spot for the trade to be worth the gamma risk.
Exit
Book 50% of max profit (premium decayed by half) within 3 days. Hard stop-loss if NIFTY breaches either strike by more than 0.5%.
Risk
Theoretically unlimited loss on both sides. Position size so a 2% adverse move costs no more than 2% of capital. Never hold into expiry if NIFTY is within 100 points of either strike.
Payoff
Profits if NIFTY stays inside [PE strike, CE strike] band. Losses grow rapidly outside it.
