Drawdown in Trading: How Losses Compound and What Recovery Takes

Every trader has losing periods. What separates an account that survives from one that does not is how deep those periods go. Drawdown is the measure of that depth, and the arithmetic behind it is unforgiving: losses and gains are not symmetrical. Understanding this is the strongest argument there is for small, fixed risk per trade.

What drawdown means

Drawdown is the fall from the highest account value to the lowest point that follows, before a new high is made.

Drawdown % = (peak − trough) ÷ peak × 100

If an account grows to $10,000 and then falls to $8,500, the drawdown is (10,000 − 8,500) ÷ 10,000 = 15%. The drawdown ends only when the account makes a new high above $10,000.

• Maximum drawdown is the largest such fall in the account's history — the number most traders and prop firms watch.
• Balance drawdown counts closed trades only. Equity drawdown includes open, floating losses, and is always at least as deep.

Why recovery is harder than the loss

After a loss, you are making gains on a smaller balance. The gain needed to get back to the peak is:

Gain needed = drawdown ÷ (1 − drawdown)

Drawdown	Gain needed to recover
10%	11.1%
20%	25.0%
30%	42.9%
40%	66.7%
50%	100%
75%	300%

Up to about 20%, recovery is close to the loss. Beyond that it accelerates. An account down 50% must double just to break even — which is why limiting drawdown matters more than chasing returns.

How risk per trade shapes a losing streak

With fixed-percentage risk, each loss takes a percentage of what is left. After n losses in a row, the account is worth (1 − risk)ⁿ of where it started.

Risk per trade	After 10 losses in a row	Drawdown
1%	90.4% of the account	9.6%
2%	81.7%	18.3%
5%	59.9%	40.1%

At 1%, ten straight losses are an uncomfortable month. At 5%, the same streak needs a gain of about 67% to repair.

Losing streaks are normal

Even a sound strategy produces long streaks. With a 50% win rate, the longest losing streak you should expect over 200 trades is around 7 to 8 losses in a row. With a 40% win rate it is longer. If your risk per trade cannot survive that many losses calmly, it is too high for the strategy — not the other way around.

Setting drawdown limits

Decide the rules before the drawdown arrives, when you are thinking clearly:

1. Daily limit: stop trading for the day after losing, for example, 3%.
2. Reduce size: at 10% drawdown, halve the risk per trade until a new high is made.
3. Pause and review: at 15–20%, stop and check whether you followed the plan or the market changed.

Halving the risk slows recovery slightly but makes a deeper hole far less likely.

Common mistakes

• Increasing lot size after losses to "win it back" — the fastest route to a deep drawdown.
• Looking only at balance while open trades carry large floating losses.
• Judging a strategy after five losses instead of a large sample.
• Risking a fixed dollar amount set when the account was larger.

Keep the risk fixed

Use the position size calculator on every trade so a fixed percentage stays fixed as the balance changes, and the risk/reward calculator to make sure winners can repair losers. Read how much to risk per trade to choose the percentage, and win rate and expectancy to judge whether a strategy is worth its drawdowns.

Key takeaways

• Drawdown = (peak − trough) ÷ peak; it ends at a new high.
• Recovery needs more than the loss: 20% needs 25%, 50% needs 100%.
• Ten losses cost about 9.6% at 1% risk and 40% at 5% risk.
• Long losing streaks are normal; size so you can survive them.
• Set daily limits and size-reduction rules before you need them.
