Daily Drawdown vs Max Drawdown: The Difference That Fails Most Accounts
Every prop firm evaluation is built from the same small set of limits, and almost every unexpected failure comes from confusing two of them. A daily drawdown limit resets every day and caps how much you may lose inside one session. A maximum drawdown does not reset and caps how far the whole account may fall. They are enforced separately, measured differently, and the daily one fails far more accounts than most traders assume.
If you remember one line
Size every trade against the daily limit, not the maximum. The daily limit is the tighter number and the one that ends evaluations. Both terms, and the static/trailing and intraday/EOD variants below, are defined in the prop firm glossary.
Two limits, two jobs
| Daily drawdown | Maximum drawdown | |
|---|---|---|
| Resets | Every trading day | Never |
| Measured from | The day's starting equity or balance | The initial balance, or the account peak if it trails |
| Typical size | 3–5% | 6–10% |
| Fails you by | A single oversized session | A slow bleed over weeks |
| Includes floating P&L | Usually yes | Usually yes |
What is daily drawdown in a prop firm?
The daily drawdown — often called the maximum daily loss — is the amount your account may fall inside a single trading day before the firm closes the evaluation. It resets at a defined point each day, usually the platform's server midnight.
Two details decide whether you breach it:
- It counts open positions. A losing trade that is still open counts against the limit. You cannot simply refuse to close it and hope. Most firms measure equity including floating P&L, commissions and swap charges, not just closed balance.
- It is measured from the day's starting point, not the day's high. If you close yesterday at a profit, today's limit is calculated from that higher figure, so your allowed loss in currency terms is larger. Some firms use closing balance, some use equity at the reset — worth confirming.
This is why the daily limit is described as "tighter than it looks" and "looser than it looks" by different people. On a flat day it is a straightforward percentage. After a profitable day, your buffer grows. After a losing day, it does not shrink to compensate.
How to calculate your daily loss limit
The arithmetic is simple, and getting it wrong once is often fatal:
- Take the account's starting point for the day — previous close or reset equity, whichever your firm uses.
- Multiply by the daily percentage. A 5% limit on a $100,000 account is $5,000.
- Subtract any floating loss already on the book. That is your remaining room, not the full figure.
- Divide by the number of trades your strategy expects to take. That is your maximum risk per trade if you want to survive a full bad day.
Worked example. $100,000 account, 5% daily limit = $5,000. You are already holding a position showing −$1,200 floating. Remaining room is $3,800, not $5,000. If your plan allows three trades a day, your maximum risk per trade for the rest of the day is $1,266 — and any trade you open with more risk than that can breach the daily limit on its own.
Static vs trailing drawdown: the second thing to learn
Maximum drawdown comes in two flavours, and the difference changes your entire approach.
Static (fixed) drawdown
The floor is fixed. If the limit is 8% of a $100,000 account, your failure line sits at $92,000 for the whole evaluation regardless of profit. Your buffer only ever grows, which makes static accounts meaningfully more forgiving.
Trailing drawdown
The floor follows your peak upward. As balance rises, the threshold rises with it, so the distance between your equity and the failure line stays roughly constant instead of widening. Some firms lock the threshold once it reaches the starting balance; others trail all the way to the target. A few trail on unrealised profit, which is the worst of the variants — the structures used by Apex and Topstep are worked through in their own guides. For the same parameters compared across FTMO, FundedNext, Apex, Topstep and FundingPips in one place, see prop firm drawdown rules explained, firm by firm.
The trap in a trailing drawdown
Unrealised profit has already moved your floor. A position sitting $1,500 in profit on a trailing account has effectively raised your failure line by $1,500. Giving it back is doubly expensive: you lose the profit and you can fall further before the limit triggers. Never treat an open winner as unspent buffer.
Does drawdown include floating loss?
At almost every firm, yes — and this is the most common source of "but I never closed it at a loss" complaints. Equity-based measurement means an open loser is a real loser the moment it is red. A few firms publish balance-based daily limits, which are dramatically more forgiving, so it is worth checking which one applies to you before you assume.
End-of-day vs intraday measurement
There is a third distinction that catches people out, and it is invisible until it fails you.
- End-of-day (EOD) drawdown is calculated on your closing balance or equity. Intraday swings do not count unless you close the day there.
- Intraday drawdown is calculated live. At no point during the session may equity touch the limit, even for a second.
A position that dips below your floor at 10am and recovers by noon is a breach on an intraday account and a non-event on an EOD one. Some firms use EOD for the maximum and intraday for the daily, which is the combination that surprises people most — and the one to check first.
How this changes what you actually do
Size against the daily limit first
The daily limit is tighter and it is the one that fails people. Risking a third of it per trade means three consecutive losses still leave you inside the day. Risking half means two ordinary losses end the account.
Know where your floor sits right now
On a trailing account, write the current failure level down each morning from your dashboard. It moves as you profit, and a trader sizing from a remembered number is sizing from a stale one.
Stop trading when the day's goal is met
The daily limit is almost never breached by a trader who has already closed the platform. It is breached by a trader who has finished their planned work and is looking for one more trade.
Avoid the pre-news position
A daily limit can be breached by a gap, not just by a sequence of losses. If you hold through a scheduled event with a stop that cannot be honoured on the first available price, the daily limit becomes a gap limit. See news trading rules and weekend holding for the events that matter.
What this looks like in practice
Take a $100,000 two-step evaluation with a 6% target, a 2% daily limit and a 6% trailing maximum. The daily limit permits a $2,000 loss; the trailing floor starts at $94,000 and rises with every dollar of profit. A trader risking $700 per trade can absorb two losses and still have room for a third. A trader risking $1,500 can absorb one, and a second ordinary loss ends the evaluation — even though the maximum drawdown has barely been touched.
That asymmetry is the whole game. Most failures are not a strategy problem; they are a position sizing problem measured against the wrong number.
Frequently asked questions
Is daily drawdown the same as daily loss limit?
Yes — the two terms describe the same rule. Some firms say "maximum daily loss", others say "daily drawdown". The one meaningful difference is whether the firm measures it on balance or on equity including floating positions.
Does my daily limit reset if I close all positions?
No. Closing positions does not reset the day. It resets at the firm's defined daily boundary, not at your last trade.
Can I breach the daily limit and still pass?
At most firms a daily-limit breach fails the evaluation immediately and you restart. A small number apply a warning or a fee. Assume it is fatal until your own firm's terms say otherwise.
Which is more dangerous, static or trailing?
Trailing, unambiguously, because your buffer does not expand as you profit and unrealised gains can move the line. If you have a choice between two evaluations at similar prices, a static drawdown is worth paying a little more for.
Summary
- The daily limit resets and fails most accounts; the maximum does not reset.
- Daily limits normally include floating loss and charges — an open loser is a real loss.
- A trailing drawdown shrinks your buffer as you profit, including from open positions.
- Check whether your firm measures intraday or end of day. It decides whether a wick is fatal.
- Size every trade against the daily limit first.
