What Is Drawdown and Why Recovery Gets Harder

Every trader loses money at times. What matters is how deep the losses go before the account turns around. That fall from a high point is called a drawdown, and understanding it is one of the most useful things you can learn about risk.

What a drawdown is

A drawdown is the decline from a peak balance to a later low, usually shown as a percentage. If your account grows to $10,000 and then falls to $8,000, you are in a 20% drawdown. The largest drawdown over a period is called the maximum drawdown, and traders often use it to judge how risky a strategy has been.

Why recovery gets harder

Losses and gains are measured against different balances. After a loss, your account is smaller, so the gain has to be calculated on a smaller base. The formula is: gain needed = 1 / (1 - loss) - 1.

Take the default example in the Drawdown Recovery Calculator. A $10,000 account falls 20% to $8,000. To get back to $10,000 you need to earn $2,000 on $8,000, which is a 25% gain, not 20%.

The gap widens quickly as losses get deeper:

• A 10% loss needs an 11.1% gain to recover.
• A 20% loss needs a 25% gain.
• A 30% loss needs a 42.9% gain.
• A 40% loss needs a 66.7% gain.
• A 50% loss needs a 100% gain. From $5,000 you must double the account to get back to $10,000.
• A 75% loss needs a 300% gain.

This is why protecting your account from deep drawdowns matters more than chasing a single big win.

How losing streaks build a drawdown

Drawdowns usually come from a series of losses, not from one trade. The size of each loss decides how deep the series cuts. Look at 10 losing trades in a row, with each loss taken as a percentage of the current balance:

• Risking 1% per trade: the account falls by about 9.6%.
• Risking 2% per trade: the account falls by about 18.3%.
• Risking 5% per trade: the account falls by about 40.1%.

Ten losses in a row may be unlikely for many strategies, but it is not impossible, and shorter streaks happen often. With a small risk per trade, a bad run is uncomfortable. With a large risk per trade, it can be the end of the account.

Two traders, the same ten losses

Imagine two traders who each start with $10,000 and both lose ten trades in a row. The first risks 1% of the current balance on each trade and ends with about $9,044. To get back to $10,000 that trader needs a gain of about 10.6%.

The second trader risks 5% per trade and ends with about $5,987. To recover, that trader needs a gain of about 67%. The strategy and the bad luck were exactly the same. Only the risk per trade was different, and it decided whether the losing streak was a small setback or a serious hole.

Recovery also takes time. A trader who needs a 67% gain has to be right, repeatedly, while sitting under pressure. That is one more reason to keep losses small while the account is still healthy.

The emotional side

Drawdowns are hard on decision making. After a few losses, many traders feel pressure to win the money back quickly. They increase their size, skip their rules or take trades they would normally avoid. Because deeper losses need bigger gains to recover, this behaviour often makes the drawdown worse. Having rules written down in advance helps you act the same way when you are under stress.

Ways to limit drawdowns

• Keep your risk per trade small and fixed as a percentage of the account. The Position Size Calculator helps you do this.
• Set a daily or weekly loss limit, and stop trading for the period when you reach it.
• Reduce your size after a certain drawdown. For example, you might halve your risk once the account is 10% below its peak.
• Avoid taking several trades that depend on the same market move, such as multiple positions on correlated pairs.
• Keep a trading journal and review it, so you can see whether losses come from your strategy or from breaking your own rules.

Drawdowns in backtests and live trading

When you look at the results of a strategy, check the maximum drawdown as well as the profit. A strategy with high returns and a very deep drawdown may be impossible to follow in real life. Remember also that past drawdowns do not set an upper limit. A live account can fall further than any historical test has shown.

Try it yourself

Enter your peak balance and a drawdown percentage into the Drawdown Recovery Calculator. It shows your balance after the drop, the gain you need to recover and the amount to make back. Trying a few values, such as 10%, 30% and 50%, is a quick way to see why keeping losses small is one of the most important habits in trading.
