Trailing Drawdown: 3 Prop Firm Breach Scenarios
End of day drawdown recalculates your maximum loss floor once a day from the closing balance, so open profit during the session does not drag the floor upwards.
Trailing drawdown is a maximum loss rule that moves a prop firm’s account threshold upwards as the account reaches new highs. Unlike static drawdown, which stays fixed below the starting balance, trailing drawdown can reduce the amount you can afford to lose even after a profitable trade.
The calculation depends on the firm’s rules. Some firms update the threshold using the highest closing balance at the end of the day. Others track the highest account equity in real time, including unrealised profit from open positions.
This distinction matters because a drawdown threshold can move up during a profitable trade, stay at its new level after the trade closes, and eventually trigger an account breach if the account falls back towards it. Some firms also lock the threshold at a specified level, while others continue trailing.
Understanding how the floor moves, when it is checked and whether it can lock helps traders assess the actual risk of a prop firm account before choosing a challenge.
How trailing drawdown works
A drawdown limit sets the lowest account value permitted under a firm’s rules. The threshold is often called the drawdown floor, maximum loss limit or liquidation threshold.
For example, a hypothetical $50,000 account with a $2,000 trailing drawdown starts with a floor of $48,000. The account has $2,000 of room before reaching that floor.
If the account reaches a new high of $51,000, the floor could move to $49,000. If the account subsequently falls to $50,000, the floor may remain at $49,000 rather than moving down with the balance.
The account is now only $1,000 above the floor, despite still being $1,000 in profit relative to its starting balance.
The exact calculation depends on the firm’s rules, including whether the reference point is balance or equity and whether the threshold eventually stops trailing.
The three main drawdown models
- Static drawdown: The floor is calculated from the starting balance and does not move as the account grows. For example, a $50,000 account with a $2,000 static drawdown has a $48,000 floor.
- End of day trailing drawdown: The threshold updates using the firm’s specified end of day reference, such as the highest closing balance. Intraday profit may not move the maximum loss threshold until the daily calculation takes place.
- Intraday trailing drawdown: The threshold follows new highs during the session. Depending on the rules, this can include unrealised profit on open positions, meaning the floor can rise before a trade is closed.
These terms are not enough to determine how an account works. You also need to check whether the calculation uses balance or equity, when the threshold is enforced, and whether a lock level applies.
For example, Maven Trading’s official drawdown documentation distinguishes between its One Step Challenge, which uses a trailing maximum drawdown based on the highest equity, and its Two Step Challenge, which uses a static maximum drawdown. Its rules also explain how unrealised profit can affect the trailing threshold.
TradeZella’s trailing drawdown explainer and PropFirmApp’s comparison of drawdown types provide additional background on the differences between these models.
Three scenarios that can breach a prop firm account
The following examples use a hypothetical $50,000 account with a $2,000 trailing drawdown. They illustrate the calculations rather than the rules of a specific firm’s account.
Scenario 1: A profitable trade moves the floor upwards
Suppose the account starts at $50,000 with a $48,000 drawdown floor.
During the session, an open trade pushes account equity to $51,000. The trader closes the trade after the profit falls back, leaving a closing balance of $50,700.
If the account uses intraday trailing drawdown based on its highest equity, the floor may have moved to $49,000 when equity reached $51,000. The floor would remain there even though the trade closed at a lower profit.
| Account measure | Amount |
|---|---|
| Starting balance | $50,000 |
| Highest equity reached | $51,000 |
| Closing balance | $50,700 |
| Illustrative trailing floor | $49,000 |
| Remaining room above the floor | $1,700 |
The trader is still $700 in profit, but the available room above the floor has fallen from $2,000 to $1,700.
Under an end of day model that uses closing balance instead, the floor might move to $48,700, assuming the same $2,000 drawdown amount and no lock level. The intraday equity peak would not determine the new floor in that example.
The lesson: A profitable trade can change the account’s risk threshold, but the effect depends on the firm’s calculation method.
Scenario 2: A losing trade leaves less room than expected
Suppose the account has reached a $51,000 high, raising its trailing floor to $49,000.
The trader then loses $800 from a balance of $50,700, leaving $49,900.
| Account measure | Amount |
|---|---|
| Balance before the loss | $50,700 |
| Trading loss | $800 |
| Balance after the loss | $49,900 |
| Trailing floor | $49,000 |
| Remaining room above the floor | $900 |
The account remains above the threshold, but only $900 of room remains.
A trader looking only at the original $50,000 starting balance might think the account has plenty of room because the balance is close to break even. The trailing floor tells a different story.
The calculation also assumes the firm does not lower the floor after a losing day. Under the illustrative trailing model, the previous high remains the reference point.
The lesson: Measure risk against the current drawdown floor, not just against the starting balance or the headline account size.
Scenario 3: An open loss breaches the floor before the close
Continue with the same account, with a balance of $49,900 and a floor of $49,000.
A new trade moves against the trader. If the account value used for enforcement falls to $48,900, it has crossed the floor by $100.
| Account measure | Amount |
|---|---|
| Balance before the trade | $49,900 |
| Illustrative account value during the trade | $48,900 |
| Drawdown floor | $49,000 |
| Amount below the floor | $100 |
If the firm’s rules enforce the floor in real time against equity or net liquidation value, the account can breach while the losing position is still open. A later recovery does not necessarily reverse that breach.
This is why end of day trailing drawdown must not be confused with end of day enforcement. Tradeify’s official trailing maximum drawdown rules state that its threshold updates at the end of the day but is enforced in real time against net liquidation value. Topstep’s Maximum Loss Limit documentation also says the limit updates at the end of the trading day and is monitored in real time using realised and unrealised profit and loss.
The lesson: Check both when the threshold updates and when a breach is triggered. They are separate parts of the rule.
These examples are illustrative only. Actual calculations, lock levels, enforcement methods and breach consequences vary by account and firm.
How prop firms apply trailing drawdown
The name of a drawdown rule does not tell you everything about its calculation. Read the rules for the specific challenge or funded account you plan to use.
Tradeify: End of day trailing with real time enforcement
Tradeify states that its Growth, Select and Lightning accounts use end of day trailing drawdown. The threshold follows the highest end of day balance, moves up when a new high is recorded, and does not move down after a losing day.
However, the firm also states that the threshold is enforced in real time against net liquidation value. Touching the threshold during a session results in a hard breach, even if the account might have recovered before the close.
Tradeify’s documentation also distinguishes evaluation accounts from Sim Funded accounts when describing its drawdown lock. The lock rules should therefore be checked for the relevant account stage.

Topstep: Maximum Loss Limit
Topstep calls its trailing threshold the Maximum Loss Limit (MLL). Its documentation says the limit rises with the end of day balance and never moves down. Once it reaches the starting balance in a Trading Combine, it locks permanently.
For the Trading Combine, Topstep lists a $2,000 Maximum Loss Limit for a $50,000 account. The limit is monitored in real time, and both realised and unrealised profit and loss count towards it.
The consequences of a breach depend on the account stage. Topstep’s documentation distinguishes between the Trading Combine and Express Funded Account, so traders should not assume the consequences are identical.

Maven Trading: Rules vary by challenge
Maven Trading’s official documentation shows that the maximum drawdown method can differ between account types.
Its One Step Challenge uses a 5% maximum drawdown trailing from the highest equity watermark, including unrealised profit. Its Two Step Challenge uses an 8% static maximum drawdown. The documentation also lists separate daily drawdown rules, which are distinct from the maximum drawdown calculation.
These differences illustrate why traders should check the exact challenge rules rather than assume that every account from the same firm uses the same model.

| Firm and account | Published drawdown method | Important detail |
|---|---|---|
| Tradeify Growth, Select and Lightning | End of day trailing | Threshold is enforced in real time against net liquidation value |

Balance versus equity: Why the difference matters
Balance generally reflects the result of closed trades, while equity also reflects unrealised profit or loss from open positions. Some firms use balance to calculate the end of day threshold, while others use equity or net liquidation value for particular calculations and enforcement.
This difference can change the amount of room available to a trader.
If an open position reaches a large unrealised profit, an equity based trailing rule may raise the floor before the position is closed. If the trade then reverses, the account may have less room than the trader expected.
An end of day balance based rule may treat the same trade differently, depending on the firm’s specified calculation time and whether open positions are included at that point.
Do not assume that a firm uses balance for every calculation simply because its drawdown is described as end of day. Check the definition of the reference value and the threshold enforcement method in the official rules.
Common trailing drawdown mistakes
- Confusing end of day updates with end of day enforcement. A threshold can update only once a day and still be enforced in real time.
- Assuming a profitable trade always increases your safety margin. A new high can raise the floor, leaving less room for a subsequent loss.
- Ignoring unrealised profit. If the firm uses equity to calculate trailing drawdown, open profit can affect the threshold before a trade is closed.
- Assuming every account has a lock level. Some models stop trailing at a specified level, while others continue to trail. Check the account’s terms.
- Using the same rules for evaluation and funded accounts. Drawdown methods and breach consequences may differ between account stages.
- Confusing maximum drawdown with daily loss limits. They are separate rules and may have different calculation methods and consequences.
How to manage risk around a trailing drawdown floor
Start by identifying the current drawdown floor and how the firm calculates it. Then calculate the distance between the account value used for enforcement and that floor.
For example, if the relevant account value is $50,700 and the floor is $49,000, the remaining room is $1,700. This is the distance to the threshold, not a recommended amount to risk.
A personal risk limit below the firm’s maximum can help prevent one trade or a short sequence of losses from reaching the threshold. Account for unrealised losses, open positions and any separate daily loss limit where applicable.
Before trading, confirm the firm’s calculation method, daily cut off time, enforcement value, lock level and breach consequences. Review these details again if you move from an evaluation to a funded account or if the firm changes its rules.
Trailing drawdown is only one part of a prop firm’s rule set. Traders should also understand the daily loss limit, consistency requirements, payout conditions and any restrictions that could affect their account.
Trailing drawdown checklist
Before choosing or trading a prop firm account, confirm the following:
- Is the maximum drawdown static, end of day trailing or intraday trailing?
- Does the calculation use balance, equity or net liquidation value?
- Does unrealised profit move the threshold?
- When does the threshold update, and which time zone does the firm use?
- Is the threshold monitored in real time?
- Does the drawdown stop trailing at a lock level?
- Are the rules different during evaluation and funded stages?
- What happens if the threshold is touched: is trading paused, or is the account breached?
- Is there a separate daily loss limit, and how does it interact with maximum drawdown?
The most important number is not the account’s advertised size. It is the distance between the value used for enforcement and the current drawdown floor, calculated according to the firm’s actual rules.
Frequently Asked Questions
Is end of day drawdown better than intraday trailing drawdown?
For most traders it leaves more room, because open profit during the session does not raise the floor. A trade that runs into profit and then comes back costs nothing under end of day rules, while an intraday trailing floor would have moved up and stayed there. The trade off is that end of day accounts sometimes cost more or come with a daily loss limit.
Can I breach an end of day drawdown during the trading day?
Yes, at most firms. The floor is only recalculated at the daily cut off, but the account value is usually monitored in real time. Topstep, for example, counts realised and unrealised profit and loss against its Maximum Loss Limit throughout the session, so an open loss that touches the floor ends the account before the close.
Does open profit count towards end of day drawdown?
Open profit does not move the floor during the session. What matters is the value recorded at the cut off. Some firms record only the closing balance, while others use the higher of balance and equity, in which case an open winner held over the cut off can raise the floor on profit that has not been banked.
When does an end of day drawdown stop trailing?
Most firms lock the floor once it reaches a set level, usually the starting balance or the starting balance plus about $100. Topstep and Hola Prime Futures lock at the starting balance. After that the floor stays fixed and any further profit becomes extra cushion. Some firms do not state a lock level, so check the help centre.
Is end of day drawdown the same as a daily loss limit?
No. End of day drawdown is the overall maximum loss floor, which trails your highest closing balance. A daily loss limit caps the loss allowed within a single day and resets every session. Many futures accounts have only the end of day drawdown, while others add a daily limit that may pause trading rather than close the account.
