A trailing stop is a stop-loss that moves with price in your favour, locking in profit as a trade works — without you having to watch it constantly. Used well, it's a powerful way to let winners run.
How it works
A normal stop sits at a fixed price. A trailing stop follows price at a set distance:
- In a long, as price rises, the stop ratchets up behind it — but never moves down.
- If price reverses by your trailing distance, the stop triggers and you exit, keeping the gains you locked in.
The distance can be a fixed amount, a percentage, or — better — based on ATR so it adapts to volatility.
Why traders use it
- Lets winners run — you don't cap your profit at a fixed target; you stay in as long as the trend holds.
- Removes emotion — it banks profit mechanically instead of you agonising over when to exit.
- Protects gains — a trade that was up big can't turn into a loss if the trail is in profit.
The trade-off
The catch: a trail that's too tight gets clipped by normal noise, knocking you out before the real move. Too wide and you give back a lot before it triggers. Matching the trail to the instrument's volatility (e.g. an ATR multiple) is the skill.
Using it well
Trailing stops suit trend-following. In choppy, ranging markets they whipsaw — a fixed target may serve better there.
A trailing stop turns "when do I take profit?" into a rule. Set the distance to the market's noise, then let the trend decide.
