What Is Drawdown in Trading?

Lose 50% and you need 100% just to get back to even. That one line explains most of risk management.

Drawdown measures how far an account has fallen from its best point. It's the honest number, because it counts the gains you gave back, not just what you started with.

In Chad's words, "The compounding effects of trading work in both directions." A drawdown shrinks your size, so "it takes that much longer" to climb back. And climbing back from a blowout? "That hill. It is so steep."

How do you calculate drawdown?

Drawdown equals the peak value minus the lowest value since that peak, divided by the peak. An account that grows to $10,000 and then falls to $8,500 is in a 15% drawdown, even if the original deposit was $7,000.

The recovery math is the part that bites. The gain needed to get back to the peak is ALWAYS larger than the drop:

• A 10% drawdown needs about an 11% gain.
• A 20% drawdown needs a 25% gain.
• A 33.5% drawdown needs about a 50% gain.
• A 50% drawdown needs a 100% gain.

Maximum drawdown is the deepest of these over a set period. Prop firm challenges enforce it as a hard rule, sometimes as a trailing limit that rises with your best balance. Long-term holders face their own version: buy-and-hold portfolios have historically sat through bear-market drawdowns of 70% or more, which is part of the HODL Paradox.

The hole gets deeper faster than it fills back in.

What drawdown do ten stops in a row actually cause?

Illustrative numbers. Two traders start at $10,000 and each hits ten stops in a row. It happens to everyone eventually.

• Trader A risks 2% per trade. After ten stops the account is about $8,170, an 18.3% drawdown. Getting back to $10,000 needs about a 22% gain. Trading at the 1:3 filter, each target reached is worth three stops, so the drawdown hurts but stays shallow enough that the same method, unchanged, can work back from it.
• Trader B risks 10% per trade. After the same ten stops the account is about $3,490, a 65% drawdown. Getting back needs a gain of about 187%. The method no longer matters; the account is too small to recover with sensible risk.

Same calls. Same chart. The only difference was the number they set before opening it, which is why risk per trade gets decided first.

What do we do when a drawdown happens?

Prevention comes first. Fixed risk per trade (1 to 2% while learning, never more than 4%), stops at the invalidation level, and a total exposure check keep any streak shallow enough to study rather than survive.

When one hits, the Decision Protocol does the work through its last two steps. The trading journal shows whether each stopped trade followed all seven decisions. If it did, the drawdown is normal variance and the plan stays the same. If it didn't, the review finds the broken step and fixes that, not the risk setting.

The rule is to trade less, not more. Niko Mercuris calls it sitting on your hands: "Sitting on your hands means stop overtrading, stop trying to get in here, get in here, get in here. Wait for the proper setup." That's also why the account should be unemotional risk capital: a drawdown in money you can learn with is a lesson, not an emergency.

What turns a drawdown into a disaster?

Sizing up to get out faster. After a run of stops, doubling the risk feels like a shortcut back to the peak, right? The recovery math says otherwise. Bigger risk makes the next streak deeper, and a deeper hole needs a much bigger gain. That's revenge trading, and it can turn a 15% drawdown into a 40% one.

The second mistake is measuring from the deposit instead of the peak. "I'm still up overall" can hide a big drawdown and the habits that caused it. At the end of the day, facts don't care about your feelings.

What drawdown number should you check today?

Measure today's balance against your peak, not your deposit. If the gap is bigger than you'd like, cut your risk per trade before the next stop.
