Where to place your stop loss: ATR, structure and common mistakes

A stop loss that is too tight gets hit by normal noise. One that is too wide risks more than you planned. Here are two practical ways to place a stop that respects how the market actually moves.

Method 1: ATR

Average True Range (ATR) measures how far an instrument typically moves. A common approach is to place the stop 1.5 to 2 times the ATR away from entry. If the 14-period ATR on a pair is 60 pips, a stop of 1.5 x ATR is 90 pips away.

Method 2: market structure

Place the stop beyond the level where your idea is proven wrong, such as below the last swing low for a long trade. If price reaches that level, the reason for the trade is gone.

Combine them

Use structure to find where the idea fails and ATR to check the stop is not inside normal noise. If the structural stop is much tighter than the ATR suggests, the trade is probably too tight to hold.

Set the size after the stop

Always choose the stop first, then calculate the position size from it with the position size calculator. Never pick a lot size and then squeeze the stop to fit.

Mistakes to avoid

• Placing stops at obvious round numbers where many others are.
• Moving the stop further away because the trade is losing.
• Using the same stop distance on every instrument.
• Ignoring spread on volatile instruments, which can trigger a tight stop.
