A 10% drawdown needs an 11.1% gain to get back to even. A 20% drawdown needs 25%, and a 50% drawdown needs a full 100% — because every recovery is earned with a smaller account than the one that took the loss. The formula is one line: required gain = drawdown ÷ (1 − drawdown). This post walks through the recovery table, why the math bites a second time when you (correctly) cut size, what a prop firm's trailing drawdown adds to the problem, how often losing streaks actually occur, and a recovery protocol you can rehearse before you need it.
The recovery table
Start with $50,000 and lose 10%. You're at $45,000, and getting back to even means making $5,000 — but now with a $45,000 account. $5,000 ÷ $45,000 = 11.1%. The loss was measured against the bigger number; the recovery is measured against the smaller one. That's the entire asymmetry, and it never goes away.
The general formula: take the drawdown as a decimal, divide by one minus the drawdown.
Required gain = drawdown ÷ (1 − drawdown)
For −10%: 0.10 ÷ 0.90 = 0.111, or +11.1%.
| Drawdown | Gain needed to break even |
|---|---|
| −5% | +5.3% |
| −10% | +11.1% |
| −20% | +25.0% |
| −30% | +42.9% |
| −50% | +100.0% |
Notice the curve isn't linear. At −5% the penalty is a rounding error. At −10% it's noticeable. At −20% you owe a quarter of your remaining account. Past −30% the required gain grows faster than the drawdown itself, and at −50% you need to double your money just to be flat. The table is why every serious risk framework treats −20% not as "a bad month" but as a structural emergency: below that line, the math starts working against you faster than your edge works for you.
Why the math bites twice
The table understates the problem, because it assumes you keep trading at full size while in the hole. Most sensible risk plans say the opposite: cut size in drawdown. That's the right call — and it makes recovery slower in trade count. Here's the arithmetic.
Take a $50,000 account risking a fixed $500 per trade (1R), with winners targeted at 2R = $1,000. A ten-trade losing streak — rough, but as we'll see below, not exotic — costs $5,000. You're at $45,000, down 10%, needing 11.1% back.
At full size, you'd need five clean 2R winners in a row to recover. With a more realistic 50% win rate, each trade is worth on average 0.5 × ($1,000) − 0.5 × ($500) = +$250 of expectancy, so the climb takes about 20 trades on average.
At half size — the correct move under most drawdown protocols — you risk $250 and winners pay $500. Expectancy per trade drops to +$125, so the same $5,000 climb now takes about 40 trades on average. Doing the right thing doubled the length of the road out.
(If you risk a fixed 1% of current equity instead of fixed dollars, ten losses dig a slightly shallower hole — about −9.6% — but your winners shrink in the hole too. Same asymmetry, different costume.)
This is where revenge sizing whispers. Double your risk to $1,000 "to get it back faster," and a routine five-loss streak — far more common than the ten that started this — costs another $5,000. Now you're at $40,000, down 20% from the peak, and the table says +25%. Every doubling attempt that fails moves you to a steeper row of the table with a smaller account. The relationship between win rate and risk-reward doesn't change because you're angry; only your size did.
On a prop account, recovery has a deadline
On your own account, a drawdown costs you percent. On a prop evaluation with a trailing drawdown, it costs you lives — a countable number of losing days left before the account is terminated.
Take the standard structure for a $50K eval: a $2,000 trail, the model Topstep uses on its 50K combine as of mid-2026. Your loss floor sits $2,000 below your highest equity mark and only ever moves up. Dig a $1,200 hole and you don't have "a 2.4% drawdown on $50k" — you have $800 of buffer left. At $200 of losses a day, that's four losing days between you and a failed eval. The recovery math above still applies, but now it runs against a clock: you must climb out before a normal losing streak lands, not just eventually.
And the trail punishes success too. Climb back, set a new equity high, and the floor ratchets up right behind you — your buffer is capped at $2,000 no matter how well the recovery goes (until the trail locks, at firms that lock it). You can never bank extra cushion for the next drawdown. Whether the floor updates end-of-day or in real time changes the tactics considerably; the EOD vs intraday trailing drawdown breakdown covers that in detail, and you can run your own buffer numbers for any firm's parameters.
This deadline mechanic is a big part of why evals chew traders up: the only substantively sourced figure says 94% fail their first challenge, and only ~7% of buyers ever receive a payout (analysis of 300k+ accounts, blog.pickmytrade.trade). Most of those failures aren't exotic — they're ordinary drawdowns colliding with a floor that doesn't forgive, a pattern the post on why traders fail prop firm challenges breaks down rule by rule.
Losing streaks are not bad luck — they're scheduled
The recovery table only matters if drawdowns actually happen, so it's worth being precise about how often they do. No heavy math required, just one number: at a 50% win rate, the chance that any six specific consecutive trades all lose is 0.5⁶ = 1 in 64. Rare-sounding — but you don't trade six times. Over a 200-trade sample, there are nearly 200 places a streak can start, and the odds compound.
| Win rate | Odds of a 6-loss streak somewhere in 200 trades (approx.) |
|---|---|
| 40% | ~97% — all but certain |
| 50% | ~80% |
| 60% | ~40% |
A coin-flip system should expect a six-loss streak in a couple hundred trades, and even an eight-loss streak shows up roughly a third of the time. If your plan can't absorb a streak that probable, you don't have a risk plan — you have a countdown. Check what your own numbers imply with the free win-rate calculator, which shows streak odds alongside expectancy.
Connect this to the table: six losses at 1% risk is roughly a −5.9% hole, needing +6.2% — annoying, recoverable. The same streak at 3% risk is a −16.7% hole needing +20%. Identical strategy, identical luck, radically different arithmetic.
A recovery protocol you can write down today
The time to design drawdown rules is before the drawdown, because in the hole your judgment is the most compromised asset you own. A workable protocol has four parts:
- Predefined size-cut tiers. For example: at −5% from equity peak, cut to 75% size. At −10%, cut to 50%. At −15%, cut to 25% and stop trading until you've completed a full review. The exact tiers matter less than the fact that they're written down before they're needed — no negotiating with yourself mid-drawdown.
- A hard daily stop. One bad day should never become the drawdown. Pick a daily loss limit, treat it as a circuit breaker, and log off when it's hit — the daily loss limits guide covers how to set one that fits your strategy's normal variance.
- No revenge doubling. Ever. The math above is the argument: sizing up in a drawdown moves you down the recovery table faster than any winning streak moves you up it.
- Journal review before resuming full size. Restoring size is earned, not scheduled. Before stepping back up a tier, review the losing stretch in your trading journal: was the streak normal variance on valid setups, or did execution degrade? Only the first kind gets its size back.
The honest part: risk caps are arithmetic, not conservatism
The standard advice — risk 0.5–1% per trade, especially on eval accounts — gets dismissed as timid. The recovery table says otherwise. At 1% risk, the near-certain six-loss streak costs ~6% and demands +6.2% back. At 3%, the same ordinary streak demands +20%, at reduced size, possibly against a trailing floor.
On a prop eval the caps are even less optional, because your real account is the trail, not the balance. On a $50K eval with a $2,000 trail, risking "1% of the account" ($500) is actually risking 25% of your effective capital per trade — four losses from termination. Risking $200–250 per trade gives the buffer 8–10 full losses of runway, which is what surviving the ~80%-probable streak actually requires. Small risk caps aren't a personality trait. They're the only numbers that survive the table.
Rehearse the climb before you need it
Drawdown discipline is a skill, and like any skill it degrades under pressure unless it's been practiced. The problem is that live markets only hand you a real losing streak occasionally — and tuition is expensive. Market replay solves the repetition problem: in TestMax, historical futures data streams bar by bar at 1x–50x with the right edge hidden, so you can deliberately load a period where your setup struggles — a low-volatility chop week on NQ, for instance — and practice executing the size-cut tiers when the sim equity actually hits −5% and −10%. The guide to backtesting a trading strategy covers building those sessions properly.
If the eval version of the problem is what you're training for, the prop-firm practice mode enforces trailing drawdown (EOD and intraday variants) and daily loss limits inside the sim, so the deadline mechanic is real when you rehearse — dig a $1,200 hole in practice and you'll feel the four-day countdown without paying a reset fee. There's a full walkthrough in the prop firm challenge practice guide, and if you're comparing platforms for this kind of work, any simulator that can enforce a trailing floor will do — the day trading simulators rundown covers the options honestly. TestMax's free plan includes three months of futures replay data with no credit card, which is enough to run a losing-streak drill this week — before the market schedules one for you.
