How to Handle a Losing Streak
To handle a losing streak, first check whether its length is unusual for your win rate before concluding anything. Then review the trades for process breaks rather than for bad luck, reduce size if the drawdown has passed your threshold, and change nothing else.
A losing streak is the ordinary experience of trading anything with an edge below certainty. What separates a survivable one from an account-ending one is entirely what gets done during it.
Before you start
A written record of the streak’s trades, so it can be examined rather than remembered. Memory during a drawdown is unreliable in a specific direction — it exaggerates.
The streak length your position size was chosen to survive, decided beforehand. If you never chose one, that is the first finding rather than a reason to skip this.
A rule for reducing size that was written before the streak began. Written during, it will be negotiated with.
The steps
1. Count the streak and check it against the odds
At a 55% hit rate over 100 trades, a run of 6 has a 54.71% chance of occurring and a run of 8 has 14.49%. Compare your streak to that before deciding it means anything.
2. Compute the drawdown in percentage terms
Six losses at 1% leaves 94.15% of the account; at 3% it leaves 83.30%. Knowing which of those you are in decides whether this is an inconvenience or a problem.
3. Read the trades for process breaks, not for bad luck
Mark each trade as followed the plan or broke it. Six rule-following losses is a normal streak. Six rule-breaking losses is a different problem with a different answer.
4. Reduce size if the drawdown passed your threshold
Halving the risk percentage cuts the probability of ruin by far more than half. Going the other way at a lower balance is the one move the arithmetic forbids.
5. Keep taking the setups, at the reduced size
An edge only pays across a sample. Sitting out until confidence returns means being absent for whatever the sample does next, which is the same market-timing error in different clothes.
6. Change nothing about the strategy itself
Adjusting an indicator length, widening a stop or adding a filter during a drawdown fits the method to the last few trades. If the strategy needs changing, that decision belongs to a scheduled review with a full sample.
7. Write down what would actually constitute evidence
“A run of 12 losses” or “expectancy negative over 200 trades” is a threshold. Without one, every streak feels like proof and none of them is.
How to tell it worked
The position size went down or stayed the same across every one of the last 20 trades. That is the single rule this whole procedure protects.
Every trade in the streak has a process grade, so you can say how many were rule breaks rather than guessing.
The strategy’s settings are unchanged from before the streak began.
And you can state the threshold that would count as evidence — a number of trades or a streak length — rather than reassessing after every result.
What the numbers say about streaks
On this site’s shared series, direction runs average 2.01 bars and the longest ran 11, across 286 runs. Clustering is the ordinary behaviour of a price series rather than a sign of anything.
95% of bars on that series sit below a prior peak, with the longest stretch under water running 73
bars — and the series still finished up 3.61%. Being in a drawdown is the normal state. The figures
are in research/series-measurements.json.
A round trip on the same series measures about 2% of the median bar range of 0.493. A streak of six is six spreads as well as six losses, which is why trading more during one makes it deeper.
What a threshold looks like
A useful threshold names a number and a consequence. “If expectancy is negative over 200 trades, the strategy stops.” “If the streak reaches 12, I halve the size and review the rules.”
Both are checkable without interpretation, which is what makes them survive a bad month. A threshold phrased as “if things do not improve” is a decision deferred rather than made.
Set it from the odds rather than from comfort. At a 55% hit rate over 100 trades a run of 8 has a 14.49% chance and a run of 10 has 3.05% — so a threshold at 8 will fire on ordinary sequences and one at 12 almost never will.

The answer to the question on that chart is that six is what a working strategy produces. At a 55% hit rate over 100 trades it is more likely to happen than not, so it carries almost no information. The streak that would be informative is around 12 — and even then the response is to check the process before concluding anything about the market.
When it fails
The failure is a size increase taken to recover faster, and it happens at the worst possible moment. The balance is at its lowest, the sequence is already running against you, and doubling the risk takes the probability of ruin from a small number to a large one — 1.83% to 13.52% on the same edge. It feels like conviction and it is arithmetically the opposite: the account has less capacity to absorb losses than it had at the start of the streak, and the response reduces that capacity further.
The second failure is stopping entirely. The edge only pays across a sample you are present for.
A third is changing the strategy mid-streak. That fits it to the last few trades.
A fourth is judging from memory. Recollection during a drawdown runs in one direction.
A fifth is having no evidence threshold. Then every streak feels like proof.
And a sixth is trading more to make it back. Six more attempts is six more spreads.

Drawdown is what a streak looks like on the equity curve and how deep is normal. Risk per trade is the figure that decides whether a streak is survivable. And trading psychology covers why the response is harder than the arithmetic.
The thing that helps most is having run the odds before it happens. Told in advance that six losses in a row is likely inside a hundred trades, a six-loss run is a scheduled event rather than a verdict. Told during the sixth loss, nobody believes it — which is why the calculation belongs in the plan rather than in the moment.
