Trading Nifty, Bank Nifty & Sensex options

Weekly expiry options are short-dated index contracts that expire every week, offering cheap premiums and fast time decay — popular for short-term trading but demanding tight risk control because they move and decay quickly.

Monthly expiry options are index and stock contracts that expire once a month, carrying more time value and slower decay than weeklies — suited to positional trades, hedging and strategies that need room to play out.

0DTE, or zero-days-to-expiry trading, means trading options on their expiry day, when time value collapses to nothing and Gamma is extreme — offering fast opportunity for sellers but severe risk for unhedged buyers.

Nifty options are contracts on the Nifty 50 index — India's most heavily traded index options — offering liquid, cash-settled exposure to the broad market with weekly and monthly expiries.

Bank Nifty options are contracts on the Nifty Bank index — a concentrated basket of major banking stocks — known for higher volatility and larger intraday swings than Nifty, attracting active traders who want faster moves.

Sensex options are BSE-listed contracts on the S&P BSE Sensex — India's oldest benchmark index of 30 large companies — providing cash-settled index exposure on the BSE with its own expiry schedule.

Position sizing is deciding how many lots to trade based on your capital and how much you are willing to lose per trade — the single most important discipline for surviving and compounding in options trading.

Risk management in options is the complete discipline of controlling losses — through position sizing, defined-risk structures, stop-losses, diversification and event awareness — so that no single trade or streak can threaten your capital.
