See exactly how your drawdown floor moves -- before you risk real money. Use this trailing drawdown calculator to add daily P&L and watch the trailing drawdown eat into your buffer in real-time.
Trailing vs Static vs EOD Drawdown
Not all drawdown rules work the same way. The type your firm uses determines how aggressively the floor chases your equity -- and how likely you are to get stopped out after a winning streak. According to TopStep's help center, roughly 80% of failed evaluations breach the drawdown limit, not the daily loss limit.
| Drawdown Type | How It Works | Example Firms | Risk Level |
|---|---|---|---|
| Static (Floor) | Max drawdown is fixed from starting balance. Floor never moves up, regardless of profits. | FTMO, FundedNext | Lower |
| Trailing EOD | Floor moves up at end of each trading day based on highest closing balance. | TopStep, Earn2Trade | Medium |
| Trailing Intraday | Floor moves up in real-time as equity increases. Every new tick high raises the floor. | Apex Trader Funding | Higher |
How Static (Floor) Drawdown Works
Static drawdown sets a fixed floor at the moment your account is created. That floor never moves, no matter how much profit you make. If you start a $50,000 FTMO challenge with a $5,000 maximum drawdown, your breach level is $45,000. Grow the account to $58,000 over two weeks? Your floor is still $45,000. You now have a $13,000 buffer between your equity and the breach point.
This is the most forgiving drawdown type because profitable trading actively increases your safety margin. Every dollar of profit adds one dollar of buffer. Firms like FTMO and FundedNext use static drawdown on their funded accounts, which is one reason they remain popular despite higher challenge fees. The psychological advantage is significant: you can take calculated risks knowing that a bad day does not erase the breathing room your earlier wins created.
The trade-off is that firms offering static drawdown typically impose tighter profit targets or stricter daily loss limits to compensate. FTMO, for example, enforces a separate daily loss limit of $2,500 on a $50,000 account -- so even though the overall floor is generous, any single day can still end your challenge if you lose more than 5% of the starting balance.
How Trailing End-of-Day (EOD) Drawdown Works
Trailing EOD drawdown updates the floor once per day, at market close. Only your end-of-day closing balance matters -- not the intraday high. Start with a $50,000 TopStep account and a $2,000 trailing drawdown. Day one, you close at $51,200. Your new floor is $49,200 ($51,200 minus $2,000). Day two, your equity spikes to $52,500 mid-session but you close at $50,800. Because $50,800 is below the previous close of $51,200, the floor stays at $49,200. The floor only ratchets up when your closing balance sets a new high.
The key advantage of EOD trailing over intraday trailing is that temporary intraday spikes do not punish you. If you enter a winning trade that briefly shows +$3,000 unrealized but you close the day at only +$1,200, the floor is based on the $1,200 close, not the $3,000 peak. This matters for scalpers and news traders who see wide intraday swings. TopStep and Earn2Trade both use this model, and TopStep converts the trailing drawdown to static once the floor reaches the original account balance on funded accounts.
The risk with EOD trailing is that multi-day winning streaks steadily ratchet the floor higher. After five consecutive green days, your buffer may be no larger than it was on day one -- even though you have made real profit. A single bad day can then breach the floor that took a week to build. Disciplined profit-taking and knowing when to stop trading for the day are essential survival tactics under EOD trailing rules.
Why Intraday Trailing Drawdown Is the Most Dangerous
Intraday trailing drawdown moves the floor in real-time with every tick of unrealized profit. Start with a $50,000 Apex Trader Funding account and a $2,500 trailing drawdown. Your floor begins at $47,500. You enter a long position on ES futures and it runs +$1,800 in your favor within minutes -- your floor instantly jumps to $49,300 ($51,800 minus $2,500). Then the trade reverses and gives back $1,200 of that unrealized gain. Your equity is now $50,600, but the floor is still $49,300 because it never moves down. Your effective buffer just shrank from $2,500 to $1,300 -- and you have not even closed a trade yet.
This is the most punishing drawdown type because unrealized gains that you never locked in still move the floor permanently. Apex Trader Funding is the most prominent firm using intraday trailing. The practical consequence is that every spike in open P&L costs you buffer, even if the trade finishes at breakeven. Traders on intraday trailing accounts must treat every open position as a ticking clock: the longer you hold a winner without taking profit, the more buffer you silently consume. Partial profit-taking at predefined levels ($500, $1,000, $1,500) is the most effective counter-strategy.
Industry data from prop firm forums suggests that intraday trailing accounts have the highest failure rate among all drawdown types. The reason is psychological: traders watch unrealized profits evaporate and then revenge-trade to recover, which accelerates the drawdown spiral. If your firm uses intraday trailing, treat the simulator above as mandatory homework before every trading week. Map out your worst-case scenario and set hard rules for when to flatten and walk away.
How to Calculate Your Remaining Drawdown Buffer
Your drawdown buffer is the distance between your current equity and the drawdown floor. The formula depends on which drawdown type your firm uses:
Static: Buffer = Current Equity - (Starting Balance - Max Drawdown)
Trailing EOD: Buffer = Current Equity - (Highest Close - Max Drawdown)
Trailing Intraday: Buffer = Current Equity - (Highest Equity Ever - Max Drawdown)
Example: you have a $150,000 Apex account with $5,000 intraday trailing drawdown. Your equity peaked at $154,200 during an open trade two hours ago. Your floor is now $149,200. Your current equity is $151,800 after partial profit-taking. Your remaining buffer is $151,800 - $149,200 = $2,600. That means you can only lose $2,600 more before your account is terminated -- even though you started with a $5,000 drawdown allowance.
Track this number before every trade. If your buffer drops below 40% of the original drawdown allowance, consider stopping for the day. In the example above, 40% of $5,000 is $2,000 -- so with $2,600 remaining, you are approaching the danger zone. The simulator at the top of this page lets you model exactly how fast the buffer shrinks under different P&L scenarios.
Frequently Asked Questions
What is trailing drawdown?
Trailing drawdown is a risk management rule used by prop firms where the maximum loss limit follows your highest equity point. As your account reaches new highs, the drawdown floor rises with it. Unlike a static drawdown that stays fixed from your starting balance, a trailing drawdown means your margin for error shrinks as you profit. For example, on a $50,000 account with $2,500 trailing drawdown, if your equity peaks at $52,000, your new floor is $49,500 -- not the original $47,500.
What is the difference between trailing and static drawdown?
Static drawdown sets a fixed floor at account opening that never moves, regardless of profits. If you start at $50,000 with $2,500 max drawdown, your floor stays at $47,500 even if your balance grows to $55,000. Trailing drawdown moves the floor up as your equity reaches new highs, so that same $55,000 peak would push your floor to $52,500. Static drawdown rewards profitable traders with a growing buffer. Trailing drawdown punishes winning streaks followed by losses because the floor has risen.
Which prop firms use trailing drawdown?
TopStep, Apex Trader Funding, and Earn2Trade use trailing drawdown (end-of-day trailing). FTMO and The5%ers use static drawdown. Some firms like FundedNext use trailing drawdown during evaluation but switch to static once funded. The trailing type (intraday vs end-of-day) matters significantly -- intraday trailing is stricter because the floor moves during the session, while EOD trailing only updates at market close.
How do I avoid hitting my trailing drawdown?
Three practical rules: (1) Size positions so no single trade risks more than 1% of your daily loss limit. (2) Take partial profits early to lock in gains without letting the drawdown floor rise too far above your current balance. (3) Stop trading for the day after hitting 50% of your daily loss limit. The biggest mistake traders make is oversizing after a winning streak -- the floor has risen, and one bad trade can breach it.
Does trailing drawdown reset?
It depends on the firm and the trailing type. End-of-day (EOD) trailing drawdown only updates at market close, so intraday spikes in equity do not raise your floor. Intraday trailing updates in real-time with every tick. Most firms do not reset trailing drawdown between phases or after payouts -- once the floor moves up, it stays there. Some firms convert trailing drawdown to static once it reaches the initial account balance (TopStep does this on funded accounts).
What happens when I breach my trailing drawdown?
When your account equity drops below the trailing drawdown floor, your account is immediately terminated. On evaluation accounts, you fail the challenge and must purchase a new one to try again. On funded accounts, you lose access to the funded capital and any unrealized profits. There is no warning or grace period -- the breach is automatic. This is why tracking your drawdown floor in real-time is critical, especially with intraday trailing where the floor moves during the session.
