What is a trailing stop?
A trailing stop is a stop you move along behind price as the trade goes your way. On a buy it only moves up, on a sell only down; it never comes back. The point is to keep a position open in a trend whose end you can't know in advance, while locking in part of the gain.
The first stop sits where the idea is invalid, and that distance is 1R. As price moves, the stop goes to entry and then past it. From then on, even getting stopped out means a profit. The trade is no longer a risky idea but a gain where you know in advance how much you could give back.
There are two ways to trail. A fixed distance: the platform keeps the stop, say, 20 pips behind price. Or structure: each time a new swing low or high forms and is confirmed, you move the stop just beyond it. This page is about the second, because the stop's location should come from the chart after entry just as it did at entry.
How do you trail a stop by structure?
Say you buy in an uptrend. Entry 1.0850, first stop under the last low at 1.0820: 30 pips, so 1R. Price rises to 1.0910, pulls back to 1.0872, then climbs again and closes above 1.0910. That confirms a new higher low. You move the stop just under it, to 1.0865. You're now 15 pips above entry; the worst case is half an R of profit.
Price runs to 1.0960, pulls back to 1.0925, then makes a new high at 1.0975. The stop moves to 1.0918. Eventually the trend breaks, price closes below 1.0925 and the stop fills at 1.0918: 68 pips, about 2.3R.
With a fixed 20 pip trailing stop instead, the stop would have been at 1.0890 when price was at 1.0910. The ordinary pullback to 1.0872 would have taken you out with 40 pips, around 1.3R, and you'd have watched the rest of the move from the side.
On a sell the rule is the same in reverse. In a downtrend, each time a new lower high is confirmed, the stop comes down to just above it. Confirmation means price turned from that high and then closed below the previous low.
Try it on a chart
Price has left a series of highs and lows on this chart. A trailing stop moves behind exactly these swings; look at the order of the highs and lows, where the last swing ended and where the current candles sit relative to it, then make your own call.
The downtrend structure holds; price corrected higher and turned back from the supply zone. What do you do?
No sign-up needed. Take a guess; when the chart opens, you'll see why.
The most common trailing stop mistake
Setting the stop by noise rather than structure. A tight fixed distance ignores the normal pullbacks a market makes every day. Even in a healthy trend, the stop gets hit the first time the trend pauses for breath.
Moving the stop before new structure exists. A pullback low isn't a valid swing low until price goes on to break the previous high. Tighten the stop a little on every candle and you end up with a stop that leaves price no room at all.
Going to breakeven too early. Pulling the stop to entry after 10 pips feels like removing risk, but price returns to entry often. That feeling usually turns into trades closed flat and moves you then miss.
And moving it back. A trailing stop goes one way only. Widening it because price is getting close puts locked-in profit back at risk.
When a trailing stop doesn't work
In a sideways market. When price chops inside a range, there's no clean sequence of highs and lows to trail behind. A fixed target at the far edge of the range is the more honest plan there.
In trends with deep pullbacks. Volatile markets often retrace hard mid-trend, and even a structure-based stop can get hit while the trend carries on.
It never catches the top. By design it sits behind the last swing, so you always give back part of the profit. If you can't accept that, a fixed target may suit you better.
It's still a stop order, so slippage and gaps apply. On some platforms an automatic trailing stop only moves while the platform is running; close it and the stop stays where it was.
Frequently asked questions
How does a trailing stop work?
As price moves in your favour the stop moves with it, and when price moves against you it stays put. On a buy it only rises, on a sell it only falls. When price finally turns and reaches the stop, the position closes with whatever gain was locked in. You can trail automatically at a fixed distance or manually behind new swing lows and highs.
How many pips should a trailing stop be?
Any fixed number is misleading. The right distance depends on the size of normal pullbacks, which differs by market, timeframe and day. A sturdier approach is to place the stop just beyond the last higher low or lower high. If you do use a fixed distance, at least measure recent pullbacks and keep the stop wider than them.
Is a trailing stop better than a fixed take profit?
It depends on the market. In a clear trend you can't know where the move ends, and a trailing stop keeps you in while it lasts. In a range the stopping point is obvious: the other edge, so a fixed target makes more sense. Some traders combine them, closing half at the first target and trailing the rest.
