Learn where to place stops, which types to use, and how to backtest stop-loss rules.
A stop loss is your insurance policy. It defines the worst-case loss before you enter a trade and removes the need for emotional decisions during a drawdown.
Types of Stops
Fixed percentage stops are simple. ATR-based stops adapt to volatility. Technical stops sit below support or structure. Time-based stops exit if the thesis does not play out quickly.
Placement Tips
Place stops outside normal market noise, not at obvious levels where clusters of orders can trigger stop runs. Wider stops require smaller position sizes.
Backtest Stop Rules
Test multiple stop distances. A stop that is too tight increases win rate but reduces average win. A stop that is too loose increases losses. The optimal point is usually in the middle.
