What Is Loss Chasing in Trading?
Category: Trading disciplineChinese: 追损
Short definition
Loss chasing is increasing exposure to a losing idea — adding to a losing position or immediately re-entering it with more size — in order to escape the loss faster rather than because the plan authorizes it.
What it means
The mechanics are simple: the position is underwater, and instead of accepting the planned loss, you add. The average entry improves, the breakeven point moves closer, and psychologically the loss begins to feel reversible. That feeling is the trap — nothing about the market's next move has changed, while your risk has roughly doubled.
Loss chasing differs from a planned scale-in by paperwork, not by chart. Averaging down can be a legitimate, pre-written tactic: the addition is sized in advance, the thesis is restated, and an invalidation still exists. Loss chasing is what happens when none of that paperwork was written — the addition is sized by the pain of the loss and justified after the fact. The same-looking trade is one or the other depending on what existed before entry.
The behavior compounds because it occasionally works. An unplanned addition that catches a bounce pays for its own bad habit, and the reinforced pattern reappears at larger size next time. FINRA's online-trading guidance is pointed about exactly this: adding to positions beyond intended size is how losses compound quickly.
The pattern in a trade log
Loss chasing is visible in the sequence of entries more than in any single one:
- Additions to a losing position that were not written in the original plan (no pre-set second entry).
- Size that grows as the position moves against you — each addition larger than the last.
- A stop that moves away as the average moves away: the invalidation point is being re-derived from your entry, not from the market.
- Immediate re-entry in the same direction after being stopped out, at worse or similar price.
- Entry reasons that reference your own average ("my breakeven is close now") instead of market conditions.
- The position's risk in R grows through the session — 1R planned, 3R+ actual.
Exit routines that pre-empt it
Loss chasing is cheapest to kill before the first add; the routine lives in the entry, not the exit:
- 1.Define the full trade at entry: how many additions are allowed, at what prices, at what fraction of original size — or write "no additions" and mean it.
- 2.Anchor the invalidation to the market: the stop goes where the thesis is wrong, and moving it requires a written new thesis, not a deeper average.
- 3.Cap total risk per idea in R (e.g., 1.5R including all additions) so chasing has a hard ceiling.
- 4.After a stop-out, enforce a re-entry cooldown for that instrument — immediate same-direction re-entry is the signature move of the pattern.
- 5.Review every losing trade for the question "did the addition exist before the first entry?" — grade the process, not the rescue.
Frequently asked questions
Is loss chasing the same as averaging down?
Not necessarily. Averaging down is the chart action (adding to a losing position); loss chasing is doing it without pre-existing paperwork. An addition written before the first entry — sized, priced, with the thesis restated — is a planned tactic; an addition sized by the pain of the loss is chasing. Judge by what existed before entry.
Why does adding feel like it reduces risk?
Because the average entry improves and breakeven moves closer — your relationship to the position gets better while your exposure to the market gets worse. Risk to your account rises even as the number on screen feels friendlier; the market does not know your average.
What if my strategy legitimately scales in?
Then the scale-in is written before the first entry: trigger conditions for each addition, fixed size fractions, a total-risk cap in R, and an invalidation that survives the adds. Under those rules the behavior is a strategy; without them, the identical trades are loss chasing with better marketing.
