How to Use Stop-Loss Orders Effectively

Overview

Stop-losses are your insurance policy. Learn where to place them, which type to use, and the common mistakes that cause traders to get stopped out unnecessarily. Combining stop-losses with the ATR indicator lets you set volatility-adjusted exits that avoid premature stop-outs. Proper stop placement goes hand-in-hand with position sizing — together they form the core of risk management.

Steps

1. 1Decide your maximum risk per trade (1-2% of account equity is the standard).
2. 2Identify a logical invalidation level — where would your trade thesis be wrong?
3. 3Place the stop-loss just beyond the invalidation level (below support for longs, above resistance for shorts).
4. 4Calculate position size: risk amount / (entry − stop-loss) = number of shares/contracts.
5. 5Choose the right order type: stop-market for guaranteed exit, stop-limit for price control.
6. 6Never move your stop-loss further away from entry — only move it to reduce risk (trail it).

Pro Tips

• Use ATR-based stops (1.5-2x ATR) to account for normal market volatility.
• Mental stops don't work — always place the order in advance.
• Avoid round-number stop-losses ($50.00) — place them at $49.87 to avoid stop-hunting clusters.
