A prop firm daily loss limit determines how much an account can lose within a trading day before reaching a specified threshold. Breaching this limit can result in a failed evaluation, a trading restriction or another consequence, depending on the firm’s rules and account type.
Understanding the calculation is essential before starting a prop firm challenge. Your remaining allowance may depend on your account balance at the daily reset, open-position losses, commissions and swaps. It is not always as simple as subtracting your closed losses from a fixed amount.
This guide explains how prop firm daily loss limits work, how to calculate your remaining allowance, and which mistakes can put your account at risk.
What Is a Daily Loss Limit in Prop Trading?
A daily loss limit is a threshold that restricts how much an account can lose during a defined trading day.
Prop firms use different calculation methods. Some calculate the limit using the account balance at the start of the day, while others use a different reference point or apply additional conditions.
The rule may also distinguish between a hard breach, which violates the account’s trading objectives, and a soft breach, which temporarily prevents further trading.
For example, a firm might set a daily loss limit of 5% on a $100,000 account. If the firm’s rules calculate that amount from the initial account balance, the daily loss allowance would be $5,000.
However, this does not mean every firm will use $100,000 as the reference balance throughout the challenge. Always check the firm’s calculation method, reset time and breach conditions.
How to Calculate a Prop Firm Daily Loss Limit
There is no universal formula for every prop firm. One common method calculates the daily loss threshold by subtracting a fixed loss allowance from the balance recorded at the daily reset.
Daily loss threshold = Reference balance − Daily loss allowance
The daily loss allowance can be calculated as:
Daily loss allowance = Initial account size × Daily loss percentage
These formulas apply only when the firm’s rules use this calculation method and a percentage of initial account capital.
Example: A $100,000 account with a 5% daily loss limit
Suppose a firm uses the previous daily reset balance and sets the daily loss allowance at 5% of the initial $100,000 account size.
- Initial account size: $100,000
- Daily loss percentage: 5%
- Daily loss allowance: $5,000
- Reference balance at the daily reset: $102,000
The daily loss threshold would be:
$102,000 − $5,000 = $97,000
Under this example, the account must remain above the applicable threshold if the rules prohibit equity from reaching or falling below it. Check the firm’s exact wording to determine whether touching the threshold also constitutes a breach.
Notice that the daily loss allowance remains $5,000, but the threshold changes because the reference balance increased.
How Open Trades Affect Your Daily Loss Limit
One of the most important details is whether the firm calculates breaches using balance or equity.
Balance generally reflects the account’s result from completed transactions, adjusted for applicable account entries.
Equity generally includes the balance plus the unrealised profit or loss on open positions, with applicable commissions, swaps and other adjustments.
When a daily loss rule uses equity, an open trade can push an account through the threshold even if the trader has not closed the position.
Worked example
Imagine an account has a daily loss threshold of $97,000.
The trader’s current balance is $100,000, but open trades are showing an unrealised loss of $2,500. Ignoring any additional charges for simplicity, the account equity is $97,500.
The trader has only $500 of room before equity reaches the $97,000 threshold.
If the floating loss increases by another $600, equity would fall to $96,900. If the firm’s rule prohibits equity from dropping below $97,000, this would breach the limit.
This is why monitoring closed profit and loss alone is not enough when a firm’s daily loss calculation includes floating losses.
Daily Loss Limit vs Maximum Drawdown
These terms are related, but they do not mean the same thing.
| Rule | What it controls | What to check |
|---|---|---|
| Daily loss limit | Losses within a defined trading day | Reference balance or equity, allowance and reset time |
| Maximum drawdown | The overall permitted loss under the account’s drawdown model | Initial balance, highest balance or equity, and whether the threshold trails |
| Trailing drawdown | A maximum loss threshold that moves according to a firm’s specified method | Whether it updates intraday, at the end of the day or at another point |
A trader can remain within the daily loss limit but breach the maximum drawdown rule. The reverse can also be possible depending on the account’s current thresholds.

Real-World Example: FTMO’s Daily Loss Rules
FTMO illustrates why traders should check the rules for their specific account type rather than assume every prop firm uses the same percentage.
According to FTMO’s official Trading Objectives, the Maximum Daily Loss is 5% of initial simulated capital for the standard 2-Step Challenge. Its 1-Step product uses a 3% Maximum Daily Loss.
FTMO also calculates its daily threshold using the balance recorded at the daily reset and subtracts the applicable fixed loss amount. Its rules account for equity, including open-position profit or loss, commissions and swaps.
For example, under FTMO’s published 1-Step calculation, a $100,000 account has a $3,000 Maximum Daily Loss amount. If the reference balance at the daily reset is $102,000, the daily threshold is $99,000.
The exact rule, reset time and consequences depend on the product. Read the applicable FTMO Trading Objectives before relying on these figures.
Common Daily Loss Limit Mistakes
1. Calculating losses from the initial balance only
Some traders assume the daily threshold always stays at the same level. If the firm’s calculation uses a balance recorded at the daily reset, the threshold can change from one day to the next.
Check which balance the firm uses and whether the loss allowance remains fixed.
2. Ignoring floating losses
If the rule is based on equity, open trades can contribute to a breach even before they are closed. Monitor unrealised losses alongside realised results.
3. Forgetting commissions and swaps
Trading costs can reduce equity and affect whether an account remains within its limit. A calculation that ignores them may overestimate the remaining allowance.
4. Assuming the reset happens at midnight local time
A firm’s trading day may reset according to its platform or server time rather than your local clock. Holding positions near the reset can be particularly important when the threshold is recalculated using a new reference balance.
Check the firm’s official time zone and account rules.
5. Confusing a soft breach with a hard breach
Some firms temporarily stop trading when a loss threshold is reached, while others treat a breach as a violation of the account’s objectives. Do not assume that a trading lockout is harmless or that every daily loss breach automatically ends an account.
Read the exact breach policy for your programme.
6. Continuing to trade after reaching the limit
Even when the platform appears to permit additional orders, you should not assume that doing so is allowed. Understand the threshold and the firm’s enforcement method before placing another trade.
How to Manage Your Daily Loss Allowance
A daily loss limit is a rule to plan around, not a target to use up.
Consider these practical steps:
- Know your threshold before trading. Record the current daily limit, its reference balance and its reset time.
- Set a personal stop for the day. You can choose to stop trading before reaching the firm’s maximum permitted loss.
- Account for open positions. Monitor equity and floating losses where the rules use equity.
- Leave room for trading costs. Commissions and swaps can affect the final result.
- Reduce risk after losses. Avoid increasing position sizes simply to recover losses within the same session.
- Recheck the rules after a reset. The threshold may change when the new trading day begins.
- Use the firm’s own dashboard or account metrics. Where available, these can help you monitor the applicable limits, but you should still understand how the rule is calculated.
No risk-management method can guarantee that a breach will never occur. The aim is to understand the rules and avoid taking unnecessary risks near the threshold.

Frequently Asked Questions
Is a daily loss limit the same as maximum drawdown?
No. A daily loss limit applies to a defined trading day, while maximum drawdown limits the overall loss under a firm’s specific drawdown method. An account may have to comply with both rules simultaneously.
Does floating loss count towards a prop firm’s daily loss limit?
It depends on the firm’s rules. If the threshold is measured using equity, unrealised profit or loss on open trades can affect whether the account breaches the limit. Balance-based calculations may work differently.
Does the daily loss limit reset every 24 hours?
Not necessarily. The reset may follow a specific server time, platform time or trading-session schedule. Check the official rules and convert the reset time to your own time zone.
Can a daily loss limit change after a profitable day?
Yes, under calculation methods that use a balance recorded at the daily reset, the threshold may move when the reference balance changes. Other programmes use different methods, so check the rules for your account.
What happens if I breach a daily loss limit?
Consequences vary by firm and account type. A breach may violate an evaluation objective, restrict trading or trigger another specified consequence. Confirm whether the rule is a hard breach or a soft breach before trading.
How much should I risk per trade in a prop firm challenge?
There is no single risk amount suitable for every trader or challenge. Position sizing should account for the remaining daily allowance, overall drawdown, instrument volatility, stop-loss distance and trading costs. A personal risk limit below the firm’s maximum can provide additional room for unexpected market movements.
Final Thoughts
Understanding a prop firm’s daily loss limit means knowing more than its advertised percentage. You also need to understand the reference balance, the treatment of open positions and trading costs, the reset time and the consequences of a breach.
Before purchasing a challenge, compare these details alongside the profit target, maximum drawdown and other trading restrictions. Use the firm’s official rules as the final reference, because calculation methods can differ between programmes and change over time.
