Drawdown in a trading prop firm is the amount your account is allowed to lose before you violate the firm's risk rules. The limit may be measured from your starting balance, highest account value or daily starting balance, depending on the firm and account type.
For example, a $100,000 simulated account with a $10,000 maximum drawdown may have a breach level of $90,000. If the firm uses a trailing drawdown, that breach level can move higher as the account reaches new peaks.
Drawdown in a Prop Firm at a Glance
| Term | Meaning | Common calculation |
|---|---|---|
| Maximum drawdown or maximum loss | The total loss allowed on the account | Starting balance minus permitted loss |
| Daily drawdown or daily loss limit | The maximum loss allowed during one trading day | Daily reference balance minus daily loss allowance |
| Static drawdown | The drawdown threshold stays fixed | $100,000 account with a $10,000 limit means a fixed $90,000 floor |
| Trailing drawdown | The threshold follows the account as it reaches new highs | Peak balance or equity minus the trailing amount |
| Balance drawdown | Calculated from closed-trade results | Balance falls below the permitted level |
| Equity drawdown | Includes open, floating profit and loss | Equity falls below the permitted level |
The term does not have one universal definition across prop firms. FTMO, Topstep and Apex Trader Funding use different combinations of maximum loss, daily loss limits, static thresholds, end-of-day trailing limits and intraday trailing limits.
How Is Drawdown Calculated?
Prop firms calculate drawdown by comparing the account's current value with a reference value, such as the starting balance, highest balance or highest equity.
The standard trading calculation is:
Drawdown in dollars = highest account value minus current account value
Drawdown percentage = drawdown divided by highest account value multiplied by 100
Example:
- Highest account value: $105,000
- Current account value: $102,000
- Drawdown: $3,000
- Percentage drawdown from the peak: approximately 2.86%
The firm's rule may use a different reference point. Some firms calculate the permitted loss from the initial account balance. Others move the loss threshold higher when the balance or equity reaches a new high.
That is why a "$100,000 prop firm account" does not automatically give you $10,000 of room. The figure that matters is the firm's maximum loss limit or drawdown threshold, not the headline account size.
What Is Maximum Drawdown or Maximum Loss?
Maximum drawdown, also called maximum loss by some firms, is the total loss an account can absorb before it fails.
Example:
- Initial account balance: $100,000
- Maximum loss: $10,000
- Breach level: $90,000
If the measured balance or equity reaches the breach level, the firm may close the account or mark the evaluation as failed.
FTMO's published example for a $100,000 2-Step account uses a $5,000 maximum daily loss and a $10,000 maximum loss. Those figures describe FTMO's rules and are not an industry-wide standard.
What Is a Daily Drawdown or Daily Loss Limit?
A daily drawdown is the maximum amount an account can lose during one trading day.
Example:
- Daily loss limit: $3,000
- Daily reference balance: $100,000
- Daily breach level: $97,000
Depending on the firm's rules, the calculation may include:
- Closed-trade losses
- Open-trade losses
- Commissions
- Swaps or financing costs
- Other platform adjustments
The daily limit usually resets at a specified time. That time may be midnight in the firm's server or reference timezone, rather than midnight in your local timezone.
FTMO calculates its maximum daily loss using account equity. The calculation includes balance, open-position profit or loss, swaps and commissions. Its 1-Step rules also specify a daily recalculation at 00:00 Central European Time.
What Is Static Drawdown?
Static drawdown has a fixed liquidation or failure threshold.
Example:
- Starting balance: $100,000
- Static drawdown limit: $1,000
- Fixed threshold: $99,000
If the account earns $3,000, the threshold remains at $99,000. The account is now further above the fixed floor, so it has more room before reaching the limit.
Topstep describes its static model as a maximum loss limit that does not move when the account grows.
Static drawdown is easier to track because profitable trading does not bring the loss threshold closer to the current balance.
What Is Trailing Drawdown?
Trailing drawdown moves higher as the account reaches new highs. It normally does not move lower after the account loses money.
Example:
- Starting balance: $100,000
- Trailing drawdown: $5,000
- Initial threshold: $95,000
- Account rises to $103,000
- New threshold: $98,000
The account can now lose $5,000 from the new peak before it breaches the rule.
Trailing drawdown can use different update methods.
End-of-Day Trailing Drawdown
An end-of-day trailing drawdown updates the threshold using the account's end-of-day balance. An intraday gain may not move the drawdown floor immediately.
Topstep states that its standard Trading Combine uses an end-of-day trailing maximum loss limit rather than trailing from every intraday peak.
Intraday Trailing Drawdown
An intraday trailing drawdown updates while you trade. A temporary unrealised profit can raise the drawdown floor, even if the trade later closes with less profit.
Apex Trader Funding's intraday evaluation rules state that the trailing threshold follows the highest account balance in real time, including unrealised gains. Touching or falling below that threshold can fail the evaluation.
This type of drawdown creates a problem for strategies that allow trades to move well into profit before retracing. The temporary peak can raise the threshold before the position is closed.
Why Does Equity Matter More Than Balance?
Balance shows closed trades. Equity shows the balance plus the current profit or loss on open trades.
Example:
- Account balance: $100,000
- Open-position loss: $2,000
- Current equity: $98,000
If the firm monitors equity, the account may be close to its drawdown threshold even though the balance still shows $100,000.
A trade that later closes profitably can still violate the rule if its temporary floating loss pushes equity below the permitted level. FTMO explains that open losses and the lowest equity value can determine whether a daily loss rule is breached.
What Happens When You Breach a Drawdown Rule?
The result depends on the firm and the type of limit:
- Evaluation failure: The challenge or assessment ends.
- Automatic liquidation: Open trades are closed when the threshold is reached.
- Account lockout: Trading stops temporarily, particularly after some daily loss limits.
- Reset requirement: You may need to reset the evaluation or purchase a new account.
- Loss of funded account: A hard breach on a funded account can terminate the account.
Not every loss limit has the same consequence. Topstep distinguishes between its maximum loss rule and some daily loss controls. FTMO describes hard loss-limit breaches as account violations.
How Is Drawdown Different From Leverage?
Leverage determines how large a position you can control. Drawdown determines how much loss the account can absorb.
Higher leverage does not increase the permitted drawdown. It can make the drawdown buffer disappear faster through oversized positions, market gaps, slippage or several correlated trades.
For risk planning, calculate position size from the drawdown limit rather than the headline account size.
On a $100,000 account with a $10,000 maximum drawdown, a $1,000 loss uses 10% of the available drawdown buffer. It represents 1% of the notional account size, but 10% of the amount you can lose before breaching the rule.
How Should Traders Manage Prop Firm Drawdown?
Before opening a trade, check the firm's current rulebook:
- Is the limit static, trailing or end-of-day trailing?
- Does it follow balance, equity or unrealised profit?
- Does the daily limit include commissions and swaps?
- What time does the daily loss limit reset?
- Does the threshold move after a profitable trade?
- Does the limit reset after a payout?
- Does touching the limit count as a breach, or must the account move beyond it?
- Are there separate daily and total loss limits?
Treat the drawdown threshold as a hard floor, not as a target. Leave room for spreads, commissions, slippage and temporary floating losses. Track equity and the remaining drawdown allowance, not only the account's profit target.
Bottom Line
Drawdown in a trading prop firm is the loss an account can take before it fails or trading is restricted. The key question is whether the limit is static, trailing, daily, balance-based or equity-based.
Before buying a prop firm challenge, identify the exact breach level and calculate how much of the drawdown buffer each trade could use. The account size attracts attention, but the drawdown rule determines how much room you have to trade.
