Cómo salir de una operación ganadora: trailing stop, objetivo fijo o cierre por tiempo
Quick answer: there is no best method, only one that fits the shape of your winners. If most of them tag the target and reverse, a fixed target wins clearly. If a few of them run much further, trailing wins by a wide margin. A time-based close does not compete with either: it is a filter for trades that have stopped moving.
Puntos clave
- The exit decides how much of the move you capture, not whether you were right.
- A fixed target raises your win rate and clips your good tail.
- A trailing stop gives back part of every move in exchange for catching the tails.
- This is not a preference. It is decided by measuring your own history.
What each method does
| Method | What it gets you | What it gives up |
|---|---|---|
| Fixed target | Captures the planned move, high win rate | Everything that comes after the target |
| Trailing stop | Captures long moves with no ceiling | Gives a slice back on every trade |
| Time-based close | Frees capital from dead positions | Can cut something about to move |
The comparison, with numbers
Take 100 trades at 1R risk, 40 of which never go in your favour. What changes is how the other 60 behave.
Case A: almost all of them tag the target and reverse
| Method | Calculation | Expectativa |
|---|---|---|
| Fixed target at 2R | 40 at −1R, 60 at +2R | +0.80R |
| Trailing giving back 1R | 40 at −1R, 60 at +1.2R | +0.32R |
Case B: the winners spread out and a few run far
| Method | Calculation | Expectativa |
|---|---|---|
| Fixed target at 2R | 25 fall short, 35 reach 2R | +0.05R |
| Trailing giving back 1R | Captures peaks at 3R and 6R | +0.88R |

Same system, same entry, opposite expectancy. The only thing that changed between the two cases is the shape of the winners. Which is why copying another trader's exit method almost never works.
How to measure your shape in 20 minutes
- Take your last 50 closed trades.
- For each one, record how far it went in your favour at its best point, in R.
- Group them: under 1R, between 1R and 2R, between 2R and 4R, above 4R.
- If almost none exceed 2R, use a fixed target.
- If at least one in five exceeds 3R, trailing probably suits you.
Where the time-based close fits
It does not replace the other two; it is added to them. If a trade has gone three hours without reaching either 0.5R or the stop, it has usually lost the momentum that justified the entry. Closing it frees capital and attention, and stops a dead position carrying you into a news release. It is particularly useful intraday, where holding something to the close rarely adds anything.
Errores comunes
- Switching method mid-trade because “it looks like it will keep going”.
- Using a trailing stop so tight that normal noise takes you out.
- Moving the fixed target further away as price approaches it.
- Comparing the two methods over twenty trades.
- Choosing trailing on an instrument that rarely makes long moves.
How to keep it fixed
What ruins all three methods is improvising halfway through. The Cortex Signal Kit delivers signals with the target defined from the start, and Cortex Automation applies the same management every time without the day's mood getting a vote. To measure the shape of your winners there is the free ebook The Trading Journal Blueprint.
So, fixed target or trailing?
It depends how many of your winners clearly exceed your target. If almost none do, fixed wins; if one in five runs much further, trailing does.
How far should the trailing stop sit?
Usually referenced to volatility, for example 1.5 or 2 ATR. A trailing stop in fixed points behaves badly when the regime changes.
Can I combine all three?
Yes, and it is common: a fixed target on part of the position, trailing on the rest, and a time-based close as a backstop. The important part is writing it down beforehand.
Does trailing lower my win rate?
Usually yes, and that is fine. What matters is expectancy, not how often you are right.
Does this apply to an automated system?
Yes, and it is easier to test there: run the same history through all three methods and compare expectancy.
