Handling Drawdowns And Losing Streaks

Most bad decisions in a drawdown come from mistaking an ordinary sequence of losses for evidence that something has broken.

Last reviewed 15 September 2026 by the MarketPro research desk · Editorial policy

In short

Write drawdown rules before the drawdown, using the streak lengths your own win rate produces. At a 45% win rate, six consecutive losses arrive roughly every 78 trades and eight every 263. Define tiers by decline from the account peak: continue unchanged at 5%, halve position size at 10%, pause and review at 15%, stop at 20%.

What to remember

At a 45% win rate, a six-loss run appears roughly every 78 trades. That is a four-month event, not a signal.
A seven-loss streak at 1% risk costs about 6.8% of the account. The damage comes from the response, not the streak.
Halving size at a defined drawdown tier keeps you executing while cutting the rate of decline.
Decay shows as a shrinking average winner at a stable win rate, or losses concentrated in one setup or session.
The execution score stays informative through a drawdown. The equity curve at 30 trades does not.

Find out what a normal losing run looks like for your strategy

Write the drawdown rules while nothing is wrong, and base them on the streak length your own win rate actually produces. Almost every bad decision made during a drawdown comes from mistaking an ordinary sequence for evidence that something has broken.

The frequency of a losing streak is computable. For a loss probability q, the expected number of trades before you first see n consecutive losses is 1/q + 1/q² + ... + 1/qⁿ. Two win rates make the point.

Streak	At a 45% win rate	At a 55% win rate
4 losses in a row	every 22 trades	every 43 trades
5 in a row	every 42 trades	every 97 trades
6 in a row	every 78 trades	every 217 trades
7 in a row	every 144 trades	every 485 trades
8 in a row	every 263 trades	every 1,079 trades

At 20 trades a month and a 45% win rate, a six-loss run is roughly a four-month event and a seven-loss run is roughly a seven-month event. Neither is a signal. Both are the shape of the strategy you already chose, and at 1% risk a seven-loss run costs about 6.8% of the account.

The three reactions that turn a dip into a hole

The drawdown itself is survivable at sensible sizing. What does the damage is the response, and it takes one of three familiar forms.

Sizing up to recover faster. Doubling risk after four losses means the fifth and sixth losses cost double, and the recovery arithmetic is already against you. Down 15% needs 17.6% to get back, down 30% needs 42.9%.
Abandoning the method. Switching strategy after a streak that your own table predicts every few months guarantees you never accumulate a sample on anything, and the new method will produce a losing run of its own within weeks.
Freezing. Skipping valid setups after a bad run removes exactly the trades the expectancy is built on, and your results then reflect a subset of the strategy chosen by anxiety.

A tiered response, decided in advance

Define the tiers by percentage decline from the account's recent peak, and write what happens at each. Numbers below are illustrative; yours should come from the streak table above and your own tolerance.

Down 5%: nothing changes. This is inside normal and the plan says so explicitly, which is the point of writing it down.
Down 10%: halve the position size. Same rules, same setups, smaller trades. You stay in the market while the cost of being wrong falls.
Down 15%: stop for five trading sessions and review the last 50 trades against the written rules before resuming, still at half size.
Down 20%: stop entirely and treat the plan as unproven until a review says otherwise.

Halving size at tier two is the load-bearing rule. It keeps you executing, which preserves the sample, while cutting the rate of further decline. The drawdown calculator will show you what each tier costs and what recovery it requires at your own risk level.

Telling ordinary variance from a strategy that has decayed

The distinction matters because the responses are opposite, and the evidence is in your journal rather than in the equity curve.

Variance looks like this: the setups still meet the written criteria, the average winner and average loser are roughly the size they have always been, and the losses are spread across setup types and sessions. Decay looks different. The average winner shrinks while the win rate holds, which usually means targets are no longer being reached because the market has stopped producing legs of that size. Or the losses concentrate in one setup type, or in one session, or in trades taken since a specific date. Or the execution score falls, in which case the strategy is fine and the problem is that you have stopped trading it.

The number worth tracking through the whole of it

Track the execution score, meaning trades that followed every written rule divided by trades taken, week by week. It is the only metric that stays informative during a drawdown, because the equity curve at 30 trades is mostly noise while the execution score is entirely within your control.

A drawdown at 100% execution is variance and the rules handle it. A drawdown at 70% execution is a different problem with a different fix, and no amount of strategy tinkering will address it. Keeping the score visible also breaks the loop where each loss makes the next deviation easier to justify, which is the mechanism described in the risk management guide and the reason a daily loss limit exists at all. Drawdowns are a real cost of trading capital rather than a hypothetical one, and planning the response in advance is what lets you answer with a rule instead of an impulse.

FAQ

Handling Drawdowns And Losing Streaks: questions

How many losses in a row is normal?

More than most people expect. At a 45% win rate, four consecutive losses turn up about every 22 trades, six about every 78, and eight about every 263. At a 55% win rate the same streaks are two to four times as rare, the gap widening with the length of the run, and still routine. A streak only carries information when it is far outside what your measured win rate predicts, which is why the table has to be computed before the streak happens.

Should I reduce position size during a drawdown?

A tiered reduction is the usual approach, because it keeps you trading the same rules while lowering the cost of being wrong. A common structure halves the position size at a 10% decline from the account peak and pauses for a review at 15%. Stopping entirely too early removes the trades the expectancy depends on, and continuing at full size through a deep drawdown risks the point where the account can no longer recover in a reasonable number of trades.

How do I know if my strategy has stopped working?

Compare the recent trades against the recorded baseline rather than reading the equity curve. Variance leaves the average winner and loser roughly unchanged with losses spread across setups and sessions. Decay usually shows as a shrinking average winner while the win rate holds, or as losses clustered in one setup type or one session. If the execution score has fallen, the strategy is not the problem.
