Prop Firm Drawdown Rules: Daily, Static, Trailing & EOD Explained

Two firms can both advertise 10% maximum drawdown and enforce completely different risks, because the floor can stay fixed, follow your equity peak, or move only at the close. The measurement method decides which trades survive, and it lives in the FAQ rather than the headline. Here are all three types, walked through with the same numbers.

One allowance, three ways to measure it

Max drawdown defines how far your account may fall before the attempt ends. Every version starts from the same idea — a $100,000 account with a 10% allowance may not lose more than $10,000 — but firms disagree on where that $10,000 is measured from.

Three answers exist: from your starting balance (static), from your highest equity so far (trailing), or from your highest end-of-day balance (end-of-day). Whichever floor applies, the breach itself is usually checked in real time, against every tick of your equity.

Keep the rule distinct from the daily loss limit, which resets each morning. Max drawdown never resets: it is one budget for the entire attempt, and the three types below are three answers to where that budget is anchored.

Daily drawdown: the limit that resets every day

Most firms pair the max drawdown with a daily loss limit, often called daily drawdown. On a $100,000 account with a 5% daily limit, equity may not fall more than $5,000 below the day's starting point, whichever way the max drawdown is measured. The day's starting point is the balance or the equity at the firm's daily reset (often midnight server time), and open losses count against it.

The daily limit is the one that ends most attempts, because it is the closer line: after a $3,000 loss, the next $2,000 decides the account, not the $10,000 total. Tap through it below.

Static drawdown: the floor never moves

Static drawdown fixes the floor at the starting balance minus the allowance: $90,000, permanently. Profit widens your cushion — at $106,000 of equity you can lose $16,000 before breaching, because the floor stayed where it was.

This is the most forgiving type and increasingly a selling point at two-step firms. Its risk profile is simple: the early days are the dangerous ones, and every dollar of profit buys back safety.

The arithmetic of survival is worth stating. With $1,000 risk per trade against a fixed $10,000 allowance, you can absorb ten consecutive full losses from day one; after banking $4,000 of profit, fourteen. No other drawdown type lets your cushion grow like this, which is why static rules suit strategies with occasional deep losing streaks.

Trailing drawdown: the floor follows your peak

Trailing drawdown raises the floor as your equity rises and never lowers it. Reach $104,000 and the floor becomes $94,000. Give back $10,000 from any peak and the attempt ends, even though you are still above your starting balance.

The harshest variant trails floating equity: an open trade that shows +$4,200 at its best raises your floor by $4,200 even if you close it at +$400. Gentler variants trail closed balances only, and at many firms the floor stops rising once it reaches the starting balance, after which the rule behaves like static.

Trailing allowances are also often smaller in practice — commonly 5% to 6% at many one-step firms rather than the 10% used here for comparison. Smaller allowance plus a moving floor is the strictest combination sold.

End-of-day drawdown: the floor moves at the close

End-of-day drawdown updates the floor only from closing balances. Intraday equity peaks do not raise it, so a winner that swings high and settles lower has cost you nothing in headroom.

Close day one at $102,000 with a $10,000 allowance and the floor becomes $92,000 at settlement. During day two your equity can dip toward that floor and recover without consequence — the same excursion that a floating-equity trailing rule might have already turned into a breach.

Check one detail in the specific rulebook: whether the breach test against that floor runs in real time or only at the close. Most firms test continuously against a floor that moves at settlement, but the gentler close-only variant exists, and the difference decides whether a deep intraday wick can end the attempt.

Same trades, three outcomes

The table runs one equity path through all three regimes, each granted the same $10,000 allowance on $100,000: a strong first day, a quiet second, and a rough third.

On day three the low of $92,600 stays $2,600 above the static floor and $600 above the end-of-day floor, but sits $600 below the trailing floor of $93,200. Identical trades pass two rulebooks and fail the third.

Look at what breached the trailing account: profit. The $103,200 peak on day one raised the floor into the path of a normal pullback. Under trailing rules, an unbanked gain is not a cushion — it is a commitment.

How each type changes your trading

Under static rules, early caution is the whole game. The floor is nearest at the start, so many traders cut size until a profit cushion exists, then trade their normal plan against a floor that only gets further away.

Under trailing rules, unrealized profit is a liability. Letting a winner run to +$4,000 and closing it flat costs $4,000 of headroom under floating-equity variants, which is why partial exits and faster profit-taking are common adaptations — and why styles that ride long trends fit these rules poorly.

Under end-of-day rules, what matters is where you settle, not where you traveled. Wide-stop positions are more survivable intraday, but a bad close locks its damage into the floor permanently.

The practical conclusion is to pick the rule set that matches how you already trade, rather than bending your trading around a cheap fee. The rest of the rulebook deserves the same reading — see prop firm rules explained — and your sizing plan should be built against the specific floor you chose, covered in risk management for funded traders.
