Prop Firm Drawdown Rules Explained: Static vs Trailing vs Daily
The number one reason traders fail prop firm challenges isn't bad strategy. It's breaking drawdown rules they didn't fully understand. Every prop firm has drawdown limits, but they calculate them differently. Confusing static with trailing, or misunderstanding how the daily limit resets, ends more challenges than bad trades.
This guide breaks down every drawdown type with real numbers so there's no ambiguity.
Type 1: Static (Absolute) Drawdown
Static drawdown is the simplest type. The breach level is set once, based on your starting balance, and never moves.
The advantage of static drawdown is that as your account grows, your buffer increases. At $115,000, you can lose $25,000 before breaching. That's 21.7% of your current equity, not just 10%.
Firms that use static drawdown: FTMO (max DD), MyFundedFX, Funded Engineer.
Type 2: Trailing (Relative) Drawdown
Trailing drawdown tracks your high-water mark (HWM). Every time your account reaches a new peak, the breach level moves up with it. The floor only moves up, never down.
Trailing drawdown is harder to manage because your buffer shrinks as you profit. With static DD, a $15,000 profit gives you a $25,000 buffer. With trailing DD, that same profit only gives you a $5,000 buffer (always 5% of HWM).
When Does the Floor Stop Trailing?
Some firms lock the trailing drawdown once it reaches your starting balance. Meaning: once you've profited enough that the floor equals your initial balance, it stops moving. This is called "trailing until breakeven" or "trailing with lock".
Check your firm's specific rules. The difference between "trails forever" and "trails until breakeven" is significant.
Firms that use trailing drawdown: The5%ers, E8 Funding, Topstep.
Type 3: Daily Loss Limit
The daily loss limit caps how much you can lose in a single day. Most firms set this at 4-5%. But the calculation base varies, and that's where confusion happens.
Method A: Based on Previous Day's Closing Balance
Your daily limit is X% of whatever your account balance was at the end of the previous trading day. If you closed yesterday at $103,000 with a 5% daily limit, today's maximum loss is $5,150. You breach if equity hits $97,850.
Method B: Based on Higher of Start Balance or Previous Equity
FTMO uses this method. The daily limit is 5% of the higher of your initial starting balance or your end-of-previous-day equity. This means a big winning day raises your daily floor for the next day.
The trader lost 5.3% of their $104,000 equity. Under method A, this would be fine (5.3% of $104k). Under FTMO's method B, it breaches because the floor was calculated from the higher starting point.
How the Three Types Interact
Most prop firms enforce two or three of these simultaneously. FTMO, for example, has all three: 10% static max DD, 5% daily DD, and the daily uses method B.
You can be safe on one rule but breach another. The daily limit is usually the tighter constraint. A 5% daily limit means you have less room on any given day than the 10% max DD suggests.
| Firm | Max DD Type | Max DD % | Daily DD % |
|---|---|---|---|
| FTMO | Static | 10% | 5% |
| The5%ers | Trailing | 6% | 4% |
| E8 Funding | Trailing | 8% | 5% |
| MyFundedFX | Static | 10% | 5% |
| Topstep | Trailing | 6% | 3% |
| Funded Engineer | Static | 10% | 5% |
Risk Sizing Based on Drawdown Type
Your drawdown type should directly influence your position sizing:
Static DD: You can afford slightly larger positions because your buffer grows with profits. A 1.5-2% risk per trade is reasonable on static accounts.
Trailing DD: You need to be more conservative because your buffer stays constant (or shrinks relative to equity). Keep risk at 0.5-1.5% per trade. After a winning streak, reduce size because the floor is closer.
Tight daily limits (3-4%): Never risk more than 1% per trade. You need room for 2-3 losing trades before hitting the daily wall. Use the Max Daily Loss Calculator to plan your position sizes based on your daily limit.
Tracking Drawdown in Real Time
Manually calculating your drawdown floor, especially trailing drawdown, is error-prone. One miscalculation and you breach without warning.
Never Miscalculate Your Drawdown Again
CopyOptic's Prop Tracker monitors your daily loss, max drawdown, and trailing drawdown in real time. It supports static and trailing modes, shows your exact floor, and warns you before you breach.
Track Your Challenge FreeThe Prop Tracker automatically detects whether you're on a static or trailing drawdown plan and calculates your floor accordingly. It also tracks daily limits, profit targets, trading days, and consistency rules across FTMO, The5%ers, E8, and custom firms.
Summary
Static drawdown is fixed from your starting balance and gets easier as you profit. Trailing drawdown follows your high-water mark and stays equally tight no matter how much you've made. Daily drawdown limits single-day losses and may float based on previous equity. Know exactly which type your firm uses, how it's calculated, and size your positions accordingly. When in doubt, risk less.
