Prop Firm Drawdown Calculator
Know your exact stop-out levels before you place a trade — daily limit, maximum drawdown, how many losses you can take, and the risk per trade that keeps you inside the rules.
Your account & rules
Presets are typical, not universal — always confirm the numbers in your own firm's rulebook.
Your limits
Most firms measure drawdown on equity, so floating losses count straight away — a position deep in the red can breach the limit before you close it.
How prop firm drawdown actually works
Almost every funded account fails for one of two reasons: a daily limit breach, or a slow bleed into the maximum drawdown. Both are avoidable arithmetic problems, which is what this calculator solves.
Daily loss limit
Measured from your balance or equity at the start of the trading day. If a 100,000 account has a 5% daily limit, dropping below 95,000 at any point — including on open positions — ends the day, and often the account. Note that the limit resets each day against the new starting balance, so after a losing day your allowance shrinks in absolute terms.
Static vs trailing maximum drawdown
A static drawdown is fixed to the initial balance: 10% on a 100,000 account means 90,000 forever, no matter how much you make. A trailing drawdown follows your highest balance, so profits raise the floor beneath you. Reach 110,000 with a 10% trail and your floor is now 99,000 — you can be up 10% and still be one bad day from failing. Many firms freeze the trail once the floor reaches the initial balance; check whether yours does.
Choosing risk per trade
Work backwards. Decide how many consecutive losses you want to survive — five is a reasonable minimum, because losing streaks of that length are ordinary — then divide your daily room by that number. On a 5% daily limit that gives 1% per trade. The lot size calculator converts that percentage into an actual position size.
Automating the limit
Discipline fails at exactly the wrong moment. The CopyConnectFX slave EA has an equity protection setting that closes every position and stops copying once equity drops past a level you set — a hard floor that does not depend on you watching the screen.
