Trailing Stop Loss

A trailing stop loss is a dynamic version of the standard Stop Loss that automatically adjusts upward (for long positions) as the stock price rises, maintaining a fixed distance or percentage below the highest price achieved. Unlike a static stop-loss that stays at one price, the trailing stop "trails" the price upward but never moves down - it only ratchets in the direction of profit.

For example, a purchase at INR 1,000 with a trailing stop loss of INR 50 starts with the stop at INR 950. If the stock rises to INR 1,100, the stop automatically moves to INR 1,050. At INR 1,200, the stop moves to INR 1,150. A reversal to INR 1,150 triggers the stop and exits the position with a profit of INR 150 per share - the bulk of the move captured, with downside protection against giving it all back.

Trailing stops solve one of the hardest problems in trading: when to exit a winning trade. Without a trailing stop, traders either exit too early (fear of losing profits) or too late (greed, hoping for more). The trailing stop automates the exit decision, letting profits run while preserving a defined share of the gains.

Not all Indian brokers support automated trailing stops natively. Zerodha Kite offers a GTT (Good Till Triggered) order that functions as a trailing stop with manual updates. Some brokers provide bracket orders with trailing stop functionality for intraday trades. Manual trailing - checking the stock price and adjusting the stop-loss order upward each day - is also common. Third-party tools and alert services support both approaches.

Trailing stop distance is calibrated to the stock's Volatility. A tight trailing stop (2% below the peak) on a volatile stock like Adani Enterprises gets triggered by normal price swings. A wider stop (8-10%) allows the trade more room but gives back more profit on a reversal. A common practice is to use a multiple of ATR (Average True Range) - for example, 2x ATR - as the trailing distance, adapting automatically to each stock's volatility profile.
