Cutting winners, defined
Cutting winners is the tendency to close a position that is currently profitable earlier than intended. In forex, this usually means exiting while the trade is still doing what you expected, but before your predefined exit conditions are reached or before the underlying reason for entry is clearly invalidated.
This is a process and psychology concept, not a strategy. The “winner” is defined by being in profit at the moment of exit; the “cut” is the mismatch between (1) what your plan would have allowed and (2) what you actually did. When the exit is driven by emotion (for example, wanting to “take the money now”) rather than by the trading thesis, the behavior is often described as cutting winners.
How it works in an easy model
A simple model is to separate two ideas:
- Planned exit rule: a rule that tells you when a position should be closed based on the trade thesis, such as reaching a target, a stop condition, or clear evidence that the thesis no longer holds.
- Actual exit decision: the real moment you close the trade, which may be influenced by fear, excitement, regret, or a feeling that “it might turn.”
Cutting winners happens when actual exit decisions happen sooner than the planned exit rule would dictate—while the thesis still appears intact. For example, assume a trade plan says “close when the thesis-based condition occurs.” If the position is profitable but you close early because you feel uncomfortable watching gains potentially shrink, you have cut a winner.
Importantly, market movement is uncertain. A trade that is profitable now can later become unprofitable, so cutting winners can sometimes reduce the chance of later losses. That is part of why the behavior can feel rational even when it undermines long-run consistency.
Example and what to compare
Consider a non-live, self-check example with assumptions stated upfront:
- You enter a forex position based on a thesis.
- Your written plan specifies an exit rule, but you sometimes exit early when the trade is up.
- Costs like spreads and commissions exist, but you are not modeling them with live numbers here.
What you can verify from your own logs is the timing gap:
- For each trade, record the moment you exited.
- Record what your plan’s thesis-based exit rule would have required (for example, “close when condition X occurs”).
- Compare “exited early while profitable” against “exited at plan condition.”
If you repeatedly close winning trades before the planned thesis-based exit, you are likely cutting winners. If you can’t define a thesis-based exit rule clearly, the concept still applies, but it becomes harder to measure.
Limitations and failure modes
Cutting winners is not automatically “wrong” in every situation, because several factors can make early exits reasonable or unavoidable:
- Execution and costs: Even with a thesis-based plan, spreads, commissions, and slippage can change whether a trade remains attractive.
- Thesis invalidation: Sometimes the “reason for entry” really does stop being true before your original target, and closing early is then a rule-based correction.
- Randomness: Forex outcomes vary. A small sample can create a false impression that early exits “work,” even if the behavior reduces average upside.
A material failure mode is confusing “early exit due to thesis change” with “early exit due to emotions.” Another failure mode is using retrospective chart feelings rather than comparing to a written exit rule.
Finally, because costs, execution quality, and market regimes differ across time and brokers, historical relationships do not guarantee future results. Independent verification should focus on your own recorded decision process, not on assumed performance averages.
How to verify it without guessing
To verify whether cutting winners is present, you can use your own journal and define two checkable fields:
- Was the thesis still valid at exit? (based on your rule, not on hindsight)
- Did you exit earlier than the plan?
Then count patterns such as “profitable at exit + exited before thesis-based condition.” If that pattern is frequent, cutting winners is likely contributing to your results.
