What is a Short Call?
A Short Call means you sell a call option and immediately receive the premium into your account. You profit if the stock stays below your strike price at expiry — the option expires worthless and you keep the entire premium. But if the stock rises sharply, your losses are theoretically unlimited. This is one of the highest-risk strategies in options.
Think of it like this: you promise to sell someone a stock at ₹22,500, and they pay you ₹80 for that promise. If the stock stays below ₹22,500, they never exercise — you keep ₹80 and do nothing. But if the stock rockets to ₹24,000, you're forced to sell at ₹22,500 while the market price is ₹24,000. That ₹1,500 gap × lot size is your loss. And there's no cap on how high the stock can go.
⚠️ Risk Warning: The Short Call has unlimited loss potential. A stock can theoretically rise to any price. This strategy should only be used by experienced traders with strict stop-losses, or as part of a defined-risk spread (Bear Call Spread). Never sell naked calls without a hedge or exit plan.

Understanding the Greeks
- Delta (negative): You lose money as the stock rises. Any rally works against you.
- Theta (positive): Time decay is your best friend. Every day without a rally earns you money.
- Vega (negative): Rising IV marks against you even without a stock move.
- Gamma (negative): Rapid rallies cause exponentially accelerating losses near expiry.

Key Points
- NEVER sell a naked call without a pre-defined stop-loss. This is non-negotiable.
- Convert to a Bear Call Spread by buying a higher-strike Call — this completely caps maximum loss.
- Close at 50% of premium received. Don't hold to expiry hoping for perfection.
- If the premium against you doubles (2× what you sold for), buy it back and exit immediately.
