Trailing Drawdown Explained: How Prop Firms Calculate It
Trailing Drawdown, Defined
Trailing drawdown is a loss limit that follows your account’s highest point, so the balance that ends your account climbs as you make profit, instead of staying fixed at your starting balance.
Trailing drawdown is the single most misunderstood rule in prop trading, and it is the reason a large share of funded traders lose accounts they thought were safe. You pass the evaluation, you have a green week, and then one ordinary pullback wipes the account out. In most cases, the trader never realized the level that would end them had quietly moved up while they were winning.
The problem is not that trailing drawdown is hidden. The problem is that it is hard to calculate in your head, and it catches you off guard exactly when you feel most comfortable. Therefore, this guide breaks down the three models firms actually use, shows you a live simulator so you can watch your liquidation level move, and covers one trap that almost no other article mentions: the withdrawal reset that turns a supposedly fixed account into a moving one.
Every firm figure below is pulled from official help documents and rule pages as of July 2026. That said, drawdown numbers change, so always confirm on the firm’s own site before you buy.
The Three Drawdown Models
Almost every prop firm uses one of three approaches to your maximum loss limit. In practice, the difference between them decides how much room you actually have once you are in profit, so it is worth learning all three before you pick a firm.
Your liquidation level is set once, from your starting balance, and it never moves. If you start at $100,000 with a 10% limit, your floor is $90,000 whether your balance climbs to $105,000 or $150,000. This is the most predictable model, and it is the one most traders prefer, because your risk math never changes.
Your floor follows your highest live equity, tick by tick, including profit that is still open and unrealized. Consequently, a spike you never actually closed can permanently raise the level that ends your account. This is the harshest version, because an intraday high you gave back still counts against you.
Your floor follows your highest closing balance, recalculated once per day after the session ends. By contrast with the intraday model, an unrealized spike you give back before the close does not count, so this version is more forgiving. Most futures firms use it, and the floor usually stops trailing once it reaches your starting balance.
The Lock: Where Trailing Usually Stops
Most trailing plans do not chase your profit forever. Specifically, the floor climbs only until it reaches your original starting balance, then it locks there for good. In other words, once you have banked enough profit to lift the floor back to breakeven, the rest of your gains are truly yours to risk. Until you reach that point, however, every new high tightens the noose.

Set your account size and loss limit, then drag your highest point and your closing balance for the day. Watch how each model moves the level that would end your account. The gap between them is the part nobody explains.
Is Trailing Drawdown Fair? An Honest Take
It would be easy to call trailing drawdown predatory, but that is not quite right. It is a feature, not a trick, and it is not black and white. Many traders simply would not choose it, because they prefer a simpler model that goes by balance and never surprises them. That preference is completely reasonable.
That said, trailing drawdown can genuinely help with risk management. Here is the honest upside: if a trailing floor is climbing behind you and you are up on the day, you probably will not keep trading. In practice, that instinct protects the win. For traders who tend to give profits back, a moving floor quietly enforces the discipline they struggle to enforce themselves.
Overall, the fair conclusion is this: trailing drawdown is harder to trade and demands that you bank profits and step away, while static drawdown gives you a fixed number you can plan around for the long term. Neither is wrong. The right choice depends on your style, and the worst outcome is only ever choosing without knowing which one you signed up for.
The Withdrawal Reset Trap
Fixed by Word Only
Here is the detail that almost no ranking article covers, and it matters more than the model itself. Some firms advertise a fixed drawdown, yet the moment you withdraw profit, they recalculate your floor from your new lower balance. As a result, an account you were told was fixed quietly behaves like a trailing one every time you get paid.
Consider a simple case. You start at $100,000 with a fixed 10% floor at $90,000. You grow the account to $110,000 and withdraw the $10,000 in profit. If the firm is truly fixed, your floor stays at $90,000. If it is fixed by word only, your floor resets to $90,000 based on the balance after withdrawal, so you have given back the cushion you earned. In other words, taking your own money made your account more fragile.
Therefore, do not take the word fixed at face value. Before you commit, ask support one direct question: after I withdraw profit, is my drawdown level still measured from my original starting balance? A firm that is truly fixed will say yes without hedging. Ultimately, that single answer separates the firms that mean it from the ones that only say it.
2026 Trailing Drawdown Rules Compared
Verified From Official Sources
The table below shows exactly which model each firm uses, by plan, so you can see who is static and who trails. Notably, the same firm often runs different models across its account types, which is why buying the wrong plan by accident is so common.
| Firm | Model | Detail |
|---|---|---|
| Forex Funds Flow | Mostly fixed | 2 Step: 12% fixed max + 4% daily. 1 Step: 6% trailing + 4% daily. Instant Boost: 3% static, no daily cap. |
| Funding Pips | Static | 1 Step, 2 Step and 2 Step Pro are static from initial balance. Only the Zero plan trails on equity and locks at the starting balance. |
| Alpha Capital | Static | Swing is 10% static plus 5% daily, measured on balance or equity. Alpha One is the only plan that trails. |
| Apex (futures) | End of day trailing | Threshold trails the highest end of day balance, recalculated at 4:59:59 PM ET, then locks at the starting balance plus $100. |
| Topstep (futures) | End of day trailing | Recalculates at the close, enforced in real time, and locks at the starting balance on funded accounts. |

Prefer a Fixed Drawdown?
If a moving floor is not for you, compare every prop firm that uses a fixed or static drawdown, side by side, and pick the one that fits your style.
How to Choose a Trailing Drawdown Plan Without Getting Caught
Start by matching the model to your style. If you scalp or day trade and tend to sit on big intraday swings, an intraday trailing plan will punish you hardest, so lean static. By contrast, if you close flat most days and want a moving floor to lock in your wins, trailing can suit you well.
Then run the two checks that actually protect you. First, confirm exactly when the floor updates, whether per tick, per closed trade, or end of day. Second, ask whether withdrawing profit resets your floor. Ultimately, a firm that answers both clearly is one you can plan around, and that clarity is worth more than any headline drawdown percentage.
