A stop order closes a losing position automatically once the market reaches a chosen price. The two common versions — the fixed stop and the trailing stop — protect capital in different ways, and each comes with its own set of trade-offs that are easy to misunderstand.
How a Fixed Stop Works
A fixed stop is set once, at a specific price, and stays there unless you move it manually. Example: a trader opens a long position on ETH at $3,000 and places a fixed stop at $2,940, which is 2% below entry. If the price later rises to $3,300, the stop still sits at $2,940 — the same 2% buffer from the original entry, now a much larger percentage below the current price. The stop only moves if the trader decides to drag it up manually, for instance to the previous swing low.
Because it does not react to price on its own, a fixed stop is predictable: the maximum loss for that trade is known the moment it's placed, which is also why it's the stop type used to size a position by a fixed percentage of account risk.
How a Trailing Stop Works
A trailing stop moves automatically as the price moves in the trade's favor, keeping a set distance — either a percentage, a fixed number of points, or an ATR multiple — behind the best price reached so far. It never moves backward.
Example: the same long ETH position at $3,000 instead carries a 3% trailing stop. As the price climbs to $3,100, the stop trails to about $3,007. At $3,300, it has trailed to $3,201. If the price then reverses to $3,200, the stop fires at $3,201, closing the trade with a gain instead of letting a 300-point advance round-trip back to breakeven or a loss.
The trade-off is that the stop can also fire on a routine pullback long before any trend actually ends, especially if the trailing distance is narrower than the market's normal swings.
Trade-offs Between the Two
The table below summarizes how the two approaches differ on a few practical points.
| Aspect | Fixed stop | Trailing stop |
|---|---|---|
| Reference point | Entry price or chart structure | Best price reached since entry |
| Moves with price | No, unless adjusted by hand | Yes, automatically, one direction only |
| Known max loss at entry | Yes, fixed in advance | Yes, until it starts trailing; then it only tightens |
| Risk of early exit on noise | Lower, if placed beyond normal swings | Higher, if the trailing distance is too tight |
| Captures open profit automatically | No | Yes, by design |
Neither version removes the underlying risk of the trade; both only define where it ends.
Common Mistakes
- Setting the trailing distance too tight. Example: a 1% trailing stop on an asset that regularly swings 2-3% within a session will often close the trade on an ordinary pullback.
- Treating a fixed stop as permanent. If the chart structure that justified the original level no longer exists, leaving the stop untouched can mean holding risk that no longer matches the setup.
- Assuming the trigger price is the fill price. Both stop types can suffer slippage in fast or thin markets; the order fires at the trigger but may fill further away.
- Widening a stop after it's already in a loss. This turns a defined risk into an undefined one and is a different decision than the stop's original purpose.
- Forgetting fees and funding when trailing tightly. Frequent small exits and re-entries can add transaction costs that a wider, less reactive stop would avoid.
Leveraged futures trading carries a high risk of loss, and no stop type — fixed or trailing — removes that risk; it only defines where a trade ends.
