A daily drawdown limit is the most you can lose in a single trading day before your account is paused or reset. Firms compute it differently: some measure against the higher of your closing balance or equity, others against equity alone, and reset times vary. Know your firm's basis and reset before you place the trade that decides your day.
What Is a Daily Drawdown Limit?
A daily drawdown limit is the largest loss a trader can take in one trading day before trading is paused or the stage resets. It is set as a share of account size and measured against balance, equity, or the higher of the two, depending on the firm. It is a limit that marks the edge of the day.
For years you may have read this as a trap set to catch you. That reading is wrong, and it is worth undoing. A daily limit is a guardrail that keeps the record intact. In a SimFi™ Training Ground, a marker at the edge of a drop keeps a developing trader from one bad session that erases a month of clean work. The limit protects the record your trading produces, which is the thing worth protecting.
How Is a Daily Drawdown Limit Calculated?
A daily limit is a fixed share of account size subtracted from a reference point set at the day's reset. Cross that distance in one day and the limit trips. Both the reference point and the reset clock vary by firm, so the same percentage behaves differently in two places. Read your firm's basis first.
Why Calculation Conventions Differ From Firm to Firm
Every business that runs assessments writes its own terms, and nobody standardized them. One firm measures a percentage of the higher of closed balance or equity. Another measures equity alone. FX2 Funding's published daily drawdown FAQ and Traderscale's instant-funding drawdown documentation use materially different bases and different reset times. The same percentage behaves differently at two firms because the reference point and the reset clock both change.
What Time the Limit Resets, and Why Reset Time Matters
The reset clock sets when the day's loss counter goes back to zero. One firm resets at a fixed evening hour in one timezone. Another resets at a set UTC hour. If you misread the clock, you place your last trade inside yesterday's window and trip a limit you thought had already cleared.
Balance or Equity: The Choice That Decides Whether an Open Loss Counts
Some firms measure the limit on closed balance, some on equity, and some on the higher of the two. When the limit is measured on equity, an open floating loss counts the moment it moves against you, so a losing position can trip the limit before you close it. Check which basis your firm uses before you hold a trade.
| Convention | What it means | When an open loss counts |
|---|---|---|
| Balance only | Measured on closed trades | Only after you close |
| Equity | Includes floating profit and loss | Immediately |
| Higher of balance or equity | Whichever is larger sets the reference | Immediately, against the higher mark |
Daily Limit vs Trailing or Maximum Limit: What's the Difference?
A daily limit caps loss within one trading day and resets at the day's clock. A trailing or maximum limit caps total loss from a floor that rises as your account grows and never falls. A trader can stay inside the daily limit and still trip the trailing one, because the two measure different things.
| Daily limit | Trailing or maximum limit | |
|---|---|---|
| Window | One trading day | The whole account |
| Resets | At the day's clock | Never, the floor only rises |
| Watches | Today's loss | Total loss from the peak |
How to Size a Position So a Bad Day Stays Inside the Limit
Work backward from the limit. Take the distance from your reference point to the limit, decide how many losing trades a bad day might hold, and size each so the worst plausible sequence stops short of the marker. Sizing for the ordinary day is how a bad day resets you.
The Three Mistakes That Breach a Daily Limit, and How to Avoid Them
Most breaches come from three avoidable mistakes in how the limit is read.
Assuming every firm uses the same basis. You carry one firm's formula to the next and get blindsided. Read the basis first.
Forgetting that open floating losses count under an equity basis. The limit trips while the trade is still open. Watch equity as the position moves, before you close.
Mistiming the last trade against the reset clock. You trade inside the wrong window. Confirm the reset hour and timezone.
What Happens When the Limit Is Reached
The consequence has two tiers. A soft breach pauses you: trading stops for a defined period, and the account continues afterward. A hard breach resets you: eligibility ends and the stage starts again. The exact thresholds vary by account and product, so read your firm's terms for the numbers.
The Bottom Line
The limit is not waiting to catch you. It marks the edge so one bad session cannot erase a month of disciplined work. Learn your firm's basis, learn its reset clock, and size for the worst version of the day. Then the marker does its job, which is to keep the record your trading produces clean enough to count.

Frequently Asked Questions
Is daily drawdown measured on balance or equity?
It depends on the firm. Some measure closed balance, some measure equity, and some use the higher of the two. Under an equity basis, open floating losses count immediately.
Do open floating losses count toward the daily limit?
Under an equity basis, yes, the moment they move against you. Under a balance-only basis, a loss counts after you close the trade. Check your firm's basis before you hold a position.
What time does the daily limit reset?
At a fixed clock set by the firm, often an evening hour in one timezone or a set UTC hour. Confirm the exact hour and timezone, because mistiming the last trade is a common breach.
What is the difference between daily and maximum drawdown?
A daily limit caps loss within one trading day and resets each day. A maximum or trailing limit caps total loss from a floor that rises and never falls. Many firms enforce both at once.
How do you avoid breaching a daily limit?
Read your firm's basis and reset clock first, watch equity when the basis is equity, and size positions so the worst plausible day stops short of the marker.
