After a Losing Run: Drawdown, Revenge Trading and When to Stop

Almost everything written about trading is written for the good weeks. This is about the other kind, because that is when accounts are actually lost — not to a single bad trade, but to the decisions made in the days after it.
The arithmetic nobody enjoys
Drawdown is the fall from an account's high point to its low point, expressed as a percentage. It is the honest measure of a strategy, because it is what you would have had to sit through to get the result.
It is also asymmetric, and the asymmetry is worse than intuition suggests:
| Drawdown | Gain needed to recover |
|---|---|
| 10% | 11% |
| 20% | 25% |
| 30% | 43% |
| 50% | 100% |
| 70% | 233% |
Lose half and you need to double what remains simply to be level. Not to be ahead — to be back where you started. This is why professional traders talk about drawdown constantly and about returns comparatively little: the return is what you keep, and the drawdown decides whether you are still there to keep it.
It is also why position size matters more than any other decision. At 2% risk per trade, ten consecutive losses — which happens to everyone eventually — costs about a fifth of the account, and a fifth needs 25% to recover. At 10% risk the same run costs about two-thirds, and two-thirds needs 200%. The strategy did not change between those two cases. Only the size did. Our position size calculator works it out in the order that keeps this survivable.
What a losing run actually does
The financial damage is the smaller half. The larger half is what a run of losses does to the way you make the next decision, and it follows a recognisable sequence.
It shortens your time horizon. A method that was designed for a week starts being judged by the afternoon. Positions get closed early because they are green, and held long because closing makes the loss real.
It makes you selective about evidence. The same chart that looked ambiguous on Monday looks like a clear setup on Thursday, because a clear setup is what you need it to be.
It moves the stop. This is the single most reliable warning sign, because it converts a loss you defined into one you have not. A widened stop is almost never a re-analysis; it is a way of not being wrong yet.
And it increases the size. The reasoning is always the same and always sounds sensible in the moment: a smaller position will take too long to recover what was lost. That is arithmetically true and it is the sentence that ends accounts.
None of this is a character flaw. It is what happens to ordinary people under loss, and it happens to experienced traders too. The difference is that experienced traders expect it and have decided in advance what they will do about it.
Revenge trading
The extreme version has a name because it is common enough to need one: trading to recover a loss rather than because conditions warrant it.
It is recognisable from the outside and almost invisible from the inside. The signals:
- The position is larger than usual and you can explain exactly why this time is different.
- It was opened within minutes of closing a loser.
- You are trading an instrument you do not normally trade.
- You are watching the profit and loss figure rather than the chart.
- You could not write down, in a sentence, why this trade would work — only what it would recover.
- You have stopped logging trades, or you skipped the last few.
That last one is worth its own line. People stop journalling exactly when the journal would be most useful, because writing it down makes it real. A gap in a trading journal is rarely a busy week; it is usually the record of a bad one.
The remedies are mechanical, not motivational
The reason "be disciplined" is useless advice is that discipline is precisely what a losing run erodes. The rules that work are the ones that do not require judgement at the moment they are needed, because judgement is the thing that has become unreliable.
A maximum daily loss. A figure — 3% of the account, or two losing trades, or whatever suits your method — after which the platform is closed for the day. Not reduced. Closed. The point is that it removes a decision rather than asking you to make a better one.
A maximum weekly loss behind it, at which you stop for the week.
A size reduction rule. After a defined drawdown — say 10% — trade at half size until the account recovers half of it. This is counter-intuitive and it is the opposite of what the urge demands, which is the point: it lengthens the runway at exactly the moment the runway matters.
A written cool-off. Twenty-four hours after hitting a daily limit before opening anything. Long enough for the urge to pass; short enough that you will actually honour it.
A re-entry condition. Decide in advance what has to be true before you return to full size — a number of trades taken correctly at half size, or a week without breaking a rule. Without one, "back to normal" means "when I feel better", which arrives at the wrong time.
Write these down before you need them, because writing them during a drawdown produces limits that conveniently accommodate the position you already have. Our trading plan guide covers where they sit in the wider plan, and the trading rules guide covers the rest of the set.
Why the demo account did not prepare you for this
Traders routinely go from profitable on a demo to losing live having changed nothing about their method, and the usual explanation — execution differences — is only a small part of it.
The real difference is that virtual money does not hurt. On a demo you hold losers calmly, take the trade you planned, and honour the stop, because none of it costs anything. The same drawdown on a live account produces an urge to intervene that no amount of demo practice built a defence against.
This is not an argument against demo accounts; it is an argument for what to use them for. A demo teaches the platform and tests a method. It cannot teach you how you behave under loss, and the only thing that does is a live account small enough that the lesson is affordable. Our demo account page sets out the four specific things a demo cannot show you.
Losing is not the same as doing it wrong
Worth stating plainly, because the opposite belief causes most of the damage above.
A method with a genuine edge still loses regularly. If it wins 45% of the time with winners twice the size of losers, it is a good method — and it will still produce runs of five and six losses, often. Treating each one as evidence that something needs fixing is how traders abandon a working approach at its worst moment and adopt a new one at random.
The question to ask after a losing run is not "what should I change?" It is "did I follow my rules?" Those are entirely different questions, and only one of them has a useful answer. A run of losses taken correctly is information about variance. A run of losses taken by breaking your own rules is information about you, and it is the more valuable of the two.
When it is not about trading any more
There is a line, and it is worth naming even though brokers rarely do.
If you are trading money you need, borrowing to trade, hiding losses from people close to you, or finding that you cannot stop when you have decided to — that is not a strategy problem and no position sizing rule will address it. It is the point at which the sensible step is to stop entirely for a period, and to talk to somebody rather than to trade through it.
Most people reading this are not in that position. Some are, and the reason it goes unaddressed is that losing money feels shameful and shame produces silence rather than questions. If any of that describes where you are, support for compulsive gambling exists in most countries and applies to trading as readily as to anything else. Closing the account for a while is a legitimate decision, not an admission.
A short checklist for a bad week
- Stop trading for the day at your limit. Today, not after one more.
- Write down every trade from the run — entry, stop, size, reason, outcome. Include the ones you would rather not.
- Mark each one: followed the rules, or did not.
- If most followed the rules, this is variance. Change nothing.
- If most did not, the problem is the rules being applied rather than the rules themselves — and the fix is a smaller size, not a better method.
- Return at half size, with a written condition for going back to full.
- Do not add a new indicator. It is the most common response and the least useful one.
If a term here was unfamiliar, the glossary covers drawdown, risk-reward and the rest in plain language.
