Max daily drawdown is the hard intraday loss limit imposed by prop firms — the maximum equity decline permitted in a single trading day before the account is automatically breached. Unlike the overall max drawdown rule, which accumulates across the life of the account, the daily drawdown limit resets every day. FTMO, FundedNext, and MyFundedFX all set this at 5%, making it the single most consequential rule in prop firm trading — responsible for an estimated 60–70% of all challenge failures.
Key Takeaways
- FTMO and most major prop firms use a fixed-dollar daily limit based on the initial account balance — the floor moves up as your EOD balance grows, but the dollar limit stays constant regardless of profits made.
- Trailing (dynamic) daily drawdown, used by some newer firms, measures from the highest intraday equity point, meaning unrealized profits that are later given back count against the limit.
- Your maximum safe position size for any trade equals your remaining daily cushion divided by the pip value at your target stop loss — this calculation must be done in real time, accounting for all open unrealized P&L.
How Max Daily Drawdown Works
Max daily drawdown defines an absolute equity floor below which you cannot go on any given trading day. Cross it by even one dollar and the account is terminated.
Before looking at the formulas, it’s important to understand that prop firms use two different methods for calculating the dollar amount of the daily limit itself:
- Fixed-dollar method (FTMO, FundedNext, MyFundedFX): The daily loss limit is always 5% of the initial account balance, regardless of profits made on prior days. On a $100,000 account, the daily limit is always $5,000 — it never grows even if the account reaches $110,000.
- Percentage-of-current-balance method (some newer firms): The daily limit scales with account growth. If the account grows to $110,000, the daily limit becomes $5,500. This is more trader-friendly but less common among major firms.
Static EOD calculation (FTMO, FundedNext, MyFundedFX):
Daily Limit = Initial Balance × Daily DD%
Daily Floor = Previous Day's Closing Balance − Daily Limit
Remaining Cushion = Current Equity − Daily Floor
On a $100,000 account with a 5% rule and a previous EOD balance of $101,500:
Daily Limit = $100,000 × 5% = $5,000
Daily Floor = $101,500 − $5,000 = $96,500
Note that as your EOD balance grows, the floor rises too — protecting more of your earned profit — but the dollar cushion available each day stays fixed at $5,000.
Trailing (dynamic) calculation:
Some firms calculate the daily drawdown from the highest intraday equity point. If a trader opens at $100,000, runs up to $102,000 unrealized, then gives it all back — the trailing firm counts that $2,000 swing against the daily limit even though it was never realized. This makes position management during volatile sessions significantly more complex.
Quick Reference
| Aspect | Detail |
|---|---|
| Formula | Daily Floor = Previous EOD Balance − (Initial Balance × Daily DD%) |
| Typical Limit | 5% of initial account balance (FTMO, FundedNext, MyFundedFX) |
| Resets | Daily — at the start of each trading day |
| Calculation Methods | Static EOD (most firms) or Trailing Intraday (some newer firms) |
| Breach Consequence | Immediate account termination — challenge fail or funded account closed |
Practical Example
A trader has passed FTMO Phase 1 and is now funded on a $100,000 account. Yesterday’s closing balance was $101,500. Today’s daily loss limit is $5,000 (fixed at 5% of the $100,000 initial balance), placing the intraday floor at $96,500.
The session starts well — the trader is up $800 on a GBP/USD long. Then NFP drops. The trader has two open EUR/USD positions at 3 lots each. Price moves 90 pips against both positions:
Unrealized loss = 2 positions × 3 lots × 90 pips × $10/pip
= 6 lots × 90 pips × $10
= $5,400 unrealized loss
Net daily P&L: +$800 (realized) − $5,400 (unrealized) = −$4,600. Only $400 of cushion remains.
The trader closes one position, locking in a $2,700 realized loss. The second position still has a $1,300 unrealized loss, bringing total daily drawdown to $4,000. Remaining cushion: $1,000. A 33-pip further move on 3 lots ($990 loss) would trigger the breach. At this point, the only rational action is to close all positions and stop trading for the day.
Max daily drawdown is the maximum loss a prop firm trader is allowed to take in a single trading day before the account is automatically closed. Most firms set this at five percent of the account balance. It resets every day but does not carry forward like the overall drawdown limit.
Common Mistakes
-
Ignoring unrealized P&L when sizing new trades. If you are already down $2,000 on open positions, your remaining daily cushion is not 5% — it is 5% minus $2,000. Traders routinely add to positions without recalculating the true remaining cushion.
-
Confusing static and trailing calculation methods. On a trailing-method firm, running up $1,500 unrealized and then giving it back counts as $1,500 of daily drawdown consumed — even if your realized P&L is flat. Always verify which method your firm uses before trading.
-
Trading full size into high-impact news. NFP and FOMC can move EUR/USD 80–120 pips in seconds. A 3-lot position on a $100,000 account can lose $3,600 in under a minute — consuming 72% of a 5% daily limit on a single candle. Many funded traders trade reduced size or flat into scheduled news.
-
Failing to track the daily floor across multiple sessions. Traders who hold positions through session rollovers sometimes lose track of whether losses accumulate against today’s or yesterday’s daily limit, especially in accounts that allow overnight holding.
How PipJournal Tracks Max Daily Drawdown
PipJournal’s daily performance dashboard displays your realized and unrealized P&L together in real time, so the remaining daily cushion is always visible without manual calculation. The risk-per-trade analytics also flag when a proposed position size would consume a disproportionate share of the remaining daily limit, helping prop traders stay within firm rules across both the challenge and funded phases.
