Drawdown Explained
Drawdown is the drop from an equity peak to the following trough. It is the truest measure of how much pain a strategy inflicts — and the number prop firms police hardest.
What drawdown measures
Drawdown is the percentage fall from a high-water mark in your account equity to the lowest point before a new high is made. A strategy can be net profitable and still have brutal drawdowns; the depth and duration of drawdown is what breaks traders psychologically.
The recovery math is asymmetric and unforgiving: a 10% loss needs an 11% gain to recover, a 25% loss needs 33%, a 50% loss needs a 100% gain, and a 90% loss needs 900%. This asymmetry is the whole argument for keeping drawdowns small.
Drawdown in prop firms
Prop firms enforce two drawdown limits: a max drawdown (total loss from the starting balance or high-water mark) and a daily loss limit. Breaching either fails the account instantly — so drawdown control isn't optional, it is the pass/fail line.
Keeping drawdown small is a direct product of small, constant position sizing and a hard daily loss cap — the same discipline that keeps risk of ruin low. Compare each firm's exact rules before you trade one.

What is drawdown in trading?
The peak-to-trough decline in account equity — how far you fall from a high point before making a new high. It measures the depth of losing periods.
Why is recovering from a drawdown so hard?
Because the math is asymmetric: a 50% loss requires a 100% gain to get back to even, and a 90% loss requires a 900% gain. Small drawdowns are far easier to recover from.
What is the difference between max and daily drawdown at a prop firm?
Max drawdown is the total allowed loss from your starting balance or high-water mark; the daily loss limit caps how much you can lose in a single day. Breaching either usually fails the account.
