What is Weekly Options?
Weekly options have short DTE — high gamma and theta for index products on NSE.
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Weekly Options shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Nifty at 24,300: weekly/monthly option chains centre on round strikes (24,000 / 24,500). Weekly Options on ATM Nifty options shifts quickly into expiry — India VIX and event risk (RBI, budget) reprice premiums independent of spot.
Bank Nifty futures perspective
Bank Nifty futures at 55,000: hedging with options or trading weekly options on Bank Nifty weekly contracts — theta and gamma rise sharply into Thursday expiry; futures leg has no time decay but carries overnight gap risk.

- Stress-test with expiry-week and event-week subsets (RBI, budget, results).

Related terms
Expiry day trading refers to executing or managing F&O positions on the last trading day of a contract series — when time value collapses, gamma rises, and pin risk around high-OI strikes intensifies. On NSE, Nifty weeklies expire Thursday; monthly series have established calendar rhythm.
Gamma is the rate of change of delta per move in the underlying. High gamma near ATM into expiry makes deltas swing quickly — especially on weekly index options.
Nifty 50 tracks 50 large NSE stocks — widely used benchmark and futures underlying.
Open interest (OI) change is the day-over-day or session change in outstanding F&O contracts. Rising OI with price up often suggests new long buildup; rising OI with price down suggests new short buildup — interpretation depends on contract series and expiry proximity.
Long straddle: buy ATM call and put. Short straddle: sell both — opposite risk profiles.
Theta measures expected premium change from passage of time, holding other factors constant. Long options usually have negative theta; short options collect theta.
