22. Can I Buy and Sell Options on the Same Day?
Yes, you can buy and sell options within the same trading day. This is called intraday options trading, where traders enter and exit an options position before the market closes. It is similar to intraday stock trading and is commonly used to profit from short-term moves in option premiums.
This flexibility allows traders to take advantage of fast price moves, volatility spikes, and directional trades — without overnight risk.
What Does It Mean to Buy and Sell Options on the Same Day?
- You can buy an option (call or put) in the morning and sell it later the same day.
- You can also sell (write) an option and buy it back within the same day.
- Both trades must be completed within equity-derivatives market hours (before 3:40 PM on NSE).
- Such trades are squared off intraday, avoiding overnight exposure and physical settlement.
Real-Life Example of Intraday Options Trade
Trading Nifty 50 Call Option (strike 22,500):
- 10:00 AM: Buy 1 lot (75 units) at ₹60 premium
- 12:30 PM: Premium rises to ₹82
- Sell the same contract at ₹82
Profit calculation:
- ₹82 – ₹60 = ₹22 gain per unit
- ₹22 × 75 = ₹1,650 total profit (before charges)
The position was closed intraday, so no expiry or settlement concerns.
Who Can Use Same-Day Options Trading?
- Retail traders: for quick profits or cutting losses early
- Scalpers: to capture small, fast premium moves
- Day traders: for strategies without overnight risk
- Experienced traders: for directional or volatility-based intraday setups
Benefits of Buying and Selling Options Intraday
- Fast profit opportunities
- Options can move 5%, 10%, or even 50% within minutes in volatile markets
- Limited risk exposure
- No overnight risk from global news or market gaps
- Lower margin (with some brokers)
- Many brokers offer intraday margin benefits for option sellers using MIS (Margin Intraday Square-off)
Risks and Considerations
- Option premiums are volatile and can swing sharply
- Time decay reduces option value as the day progresses
- Illiquid contracts may be hard to trade efficiently
- Slippage and unfavorable fills can occur in fast markets
Risk control methods: use stop-losses, trade liquid contracts, avoid illiquid stock options.
Liquidity Is Critical for Same-Day Trades
Focus on:
- Indices like Nifty 50 and Bank Nifty
- Active stocks such as Reliance, HDFC Bank, Infosys
- ATM or near-the-money strike prices
These usually offer high open interest, tighter spreads, and better execution.
Strategies for Intraday Options Trading

| Scalping | Quick trades for small premium moves | Works best in Nifty/Bank Nifty |
