Why losses cost more than they look
Percentages are not symmetrical, because they are calculated on different numbers. Lose 20% of $10,000 and you have $8,000 - and 20% of $8,000 is only $1,600, which leaves you short. You need 25% to get home. The deeper the hole, the worse the maths gets, and past about 50% it stops being arithmetic and starts being a career decision.
The cost nobody prices: time
The gain percentage is only half the bill. The other half is the months of disciplined trading it takes to produce it, during which the temptation to size up and "make it back" is strongest. That is the real reason small, fixed risk wins: it is not about being timid, it is about never buying a problem this expensive.
Where deep drawdowns actually come from
Rarely from one bad idea. Usually from three: oversized positions, several trades that are secretly the same bet, and revenge-trading after the first two. Each has a fix - the position size calculator, a correlation check, and the pre-trade checklist.
See it happen before it happens
The risk of ruin simulator runs thousands of accounts with your win rate and risk setting and shows how deep the typical drawdown gets. Most traders are shocked by how normal a 20% dip is inside a system that still ends the year up.
The full asymmetry table
| Drawdown | Gain needed | Winning trades at 1% each | What it means |
|---|---|---|---|
| −5% | +5.3% | 6 | A normal bad week |
| −10% | +11.1% | 11 | A normal bad month |
| −20% | +25.0% | 23 | Recoverable with discipline |
| −30% | +42.9% | 36 | Most funded programmes close you here |
| −50% | +100% | 70 | You now need to double |
| −80% | +400% | 162 | Statistically, the account is over |
The trade-count column is the one people skip, and it is the real bill. Climbing out of a 50% hole at a steady 1% per winning trade means seventy winners in a row with no losses in between, which nobody has ever done. Add realistic losses and the true figure is several times that.
Where deep drawdowns actually come from
Rarely from one bad idea. Almost always from three compounding together: positions sized too large, several trades that are secretly the same bet, and revenge-trading after the first two. Each has a specific fix - the position size calculator for the first, a correlation check for the second, and the pre-trade checklist for the third.
The rule that prevents the hole
Set a monthly stop before the month starts. At a fixed percentage down, you stop trading until the next period and spend the time reviewing instead. It feels arbitrary, and that is the point: the decision is made while you are calm, by someone who is not currently losing. Traders who survive long enough to compound almost all have some version of this rule, and the ones who do not usually learn it from a number in the bottom half of the table above.
Frequently asked
How much do I need to gain to recover a 50% loss?
You need +100%. The gain is calculated on the smaller balance left after the loss, so a 50% drawdown needs a double just to return to even. The formula is gain = drawdown ÷ (1 − drawdown): 20% needs 25%, 30% needs 42.9%, 50% needs 100%, 80% needs 400%.
What counts as a normal drawdown?
Even profitable systems spend long stretches under water. Single-digit drawdowns are routine, 10-20% is uncomfortable but survivable, and past about 30% most funded-account programmes have already closed you. The number that matters is not what you can tolerate on a spreadsheet but what you can keep following your rules through.
How do I avoid deep drawdowns?
Cap risk per trade at 1% or less, avoid stacking correlated positions that are really one bet, and set a hard monthly stop at which you stop trading and review. Deep drawdowns are almost always a sizing problem rather than a strategy problem.
Should I increase my size to recover faster?
No. Increasing risk after losses is the most reliable way to turn a recoverable drawdown into a closed account, because the larger size arrives exactly when your judgement is worst. Professional practice is the opposite: cut size while under water and earn the right to scale back up.
How long does it take to recover a drawdown?
Longer than the percentage suggests, because you also have to keep not losing. At an average 1% gain per winning trade, climbing out of a 25% drawdown takes about 29 consecutive winning trades. Real recoveries include more losses along the way, which is why the time cost usually exceeds the maths cost.
What is maximum drawdown and why do funds report it?
Maximum drawdown is the largest peak-to-trough fall in account equity over a period. Funds report it because it describes the worst experience an investor would have had, which return alone hides. A strategy returning 30% a year with a 60% maximum drawdown is not the same product as one returning 15% with an 8% drawdown.
Does drawdown mean my strategy is broken?
Usually not. Every positive-expectancy system has drawdowns, and abandoning one during a normal losing streak is the most common way traders convert a working method into a loss. Know your expected drawdown in advance so a normal one does not feel like evidence.
