In this article, intraday drawdown means an end-of-day, non-trailing daily loss limit: a single equity check at session close that decides whether a funded account remains valid. Traders who want predictable rules tend to prefer this model because it does not punish a temporary dip during the trading day. The next move is simple: scan the rulebook checklist below before you fund or evaluate any account.
TL;DR:
A $50,000 nominal account backed by $25,000 in actual funds turns a 5% nominal limit into a 10% loss against funds at risk.
Set position size by dividing the daily limit across planned trades and by stop distance; keep a session stop below the full allowance.
Before paying, confirm the snapshot time zone, whether open positions count, how partial funding converts the limit, and whether fees use nominal or actual value.
Ask the provider for a worked example in writing; treat vague answers, disguised trailing limits, missing funding formulas, or unpublished payout thresholds as warning signs.

How end-of-day, non-trailing drawdown rules actually work
An end-of-day drawdown rule checks your account equity once, at session close, against a fixed loss limit. If you stay above that line when the market closes, the day counts as clean no matter what your equity did in between. That single detail is what “non-trailing” means here: the limit does not follow your highest intraday equity peak, it just waits for the closing number.
Three things determine how the math plays out:
-
Check timing: the rule only evaluates equity at the defined session close, not continuously throughout the day.
-
Equity versus nominal size: when an account is fully funded, the dollar limit is a straight percentage of the account’s full nominal value.
-
Partial or notional funding: when a provider funds less than the nominal size, the NFA’s disclosure guidance says performance and drawdown calculations should still reference the nominal account size, which changes the effective percentage relative to actual funds.
Regulatory language adds useful context even though it was not built for prop trading accounts. The eCFR’s Part 4 rules define drawdown as a peak-to-valley decline measured in month-end net asset value, a reporting standard for commodity pools. Funded-account rulebooks borrow the spirit of that concept but apply it daily rather than monthly, so always read the provider’s own clause rather than assuming it matches the regulatory definition word for word.
Worked examples: running the end-of-day math yourself
The clearest way to understand an end-of-day limit is to calculate it.
-
Scenario A, fully funded $100,000 account with a 5% EOD limit. The dollar limit equals $5,000. If your equity closes the session at $96,200, you are still above the floor and the day is clean. If it closes at $94,800, the account has broken the rule, even if equity dipped to $93,000 at some point and partially recovered.
-
Scenario B, partially funded account. When actual funding is lower than the nominal size, the NFA guide for CTAs describes converting rates using the nominal-over-actual ratio multiplied by the stated rate. A $50,000 nominal account funded with $25,000 actual dollars effectively doubles the percentage impact of every dollar lost, so a 5% nominal limit behaves like a 10% limit against the funds actually at risk.
-
Scenario C, intraday recovery versus persistent loss. A dip to $90,000 during the session that recovers to $97,500 by close passes, since only the closing number counts. A dip that never recovers and closes below the floor breaks the account regardless of how the day looked at 11 a.m.
Pro Tip: Write your own EOD dollar limit on a sticky note before the session opens: nominal size times the stated percentage, converted for actual funds if you are notionally funded.
Turning the end-of-day rule into position sizing you can trust
Once you know your dollar limit, risk management becomes a sizing problem rather than a guessing game. Divide your daily dollar limit by the number of trades you plan to take, then divide that by your stop distance in ticks or points to get a contract size that keeps you inside the rule even on a losing day.
A few habits make this easier to hold to in practice:
-
Set a hard session stop equal to a fraction of your daily limit, not the whole amount, so one bad trade cannot end your day.
-
Take partial profits on winners to build a cushion before the riskier parts of the session.
-
Predefine your stop level on every trade before entry, rather than deciding in the moment.
-
Recalculate position size whenever your account is notionally funded, since the effective leverage against actual funds is higher than the nominal percentage suggests.
Partial funding deserves extra caution. Pairing a conservative intraday stop with the EOD rule means you rarely get close to the daily limit on any single day, leaving room for the normal variance that comes with active trading.
Pro Tip: Treat your daily dollar limit as a ceiling you never plan to touch, not a target you size trades around.
Checklist: what to verify in a rulebook before you sign or pay
Before paying for an evaluation, confirm these clause-level details with the provider:
-
Check time: when exactly is the end-of-day equity snapshot taken, and in what time zone?
-
Calculation basis: is the limit a flat dollar amount or a percentage, and of which figure?
-
Unrealized versus realized P&L: does the closing check include open positions marked to market, or only closed trades?
-
Nominal versus actual funding disclosure: if the account is partially funded, is the conversion formula published anywhere?
-
Fee structure tied to nominal size: are evaluation or activation fees calculated against the nominal or actual account value?
Ask support directly for a worked example day showing the math, and treat a vague or evasive answer as a warning sign. Legitimate providers publish clear payout thresholds, state plainly that there are no hidden fees, and let you start practice trading before you commit. Red flags include a trailing clause dressed up as an end-of-day rule, nominal-funding math that is never spelled out, or payout thresholds that are missing entirely.
Why we design around end-of-day, non-trailing drawdown
We built our rules around a single end-of-day equity check because it removes the guesswork that trailing, intraday-sensitive limits create. A trader who understands exactly when the clock stops can plan a session with confidence instead of watching every tick for fear of a floor that moves against them. Pairing that with no consistency rules means a strong day early in an evaluation does not box you into matching it later.
This approach is a trade-off, not a universal fix. Non-trailing rules are simpler to reason about, but a trader who thrives on a tighter, more reactive risk model may find a trailing structure gives different feedback during fast markets. We think transparency wins for most traders evaluating funded accounts, which is why the rulebook itself, not fine print buried in support tickets, carries the weight of that claim.
Start a practice evaluation and test the end-of-day rule yourself
The fastest way to confirm how an end-of-day drawdown behaves is to trade it, not just read about it. Practice trading can start instantly upon signing up for an evaluation, so you can run a few sessions against the checklist above before any money is on the line.
A few things make that process straightforward:
-
Transparent end-of-day rules with no trailing clause chasing your unrealized gains.
-
Clear payout thresholds published up front, with no hidden fees added after funding.
-
No platform switching once you move from evaluation to funded status.
-
Traders generally keep a high percentage of their earnings from their payouts onward.
Before you commit, it also helps to confirm how realistic your drawdown expectations are. A partner resource like Backtestify’s guide to backtesting a strategy walks through how to estimate win rate and max drawdown using historical data, which pairs well with a practice session built around a published end-of-day limit.
Start with a 25K, 50K, or 100K evaluation, run a handful of practice days using the checklist in this article, and confirm the math matches what the rulebook states before you pay for anything larger.
FAQ
What does “intraday drawdown” mean for a funded trading account?
In a funded-account context, it refers to an end-of-day, non-trailing loss limit checked once at session close rather than continuously throughout the day. Equity can dip during the session without breaking the rule, as long as it recovers by the close.
How is an end-of-day drawdown limit calculated?
The limit is typically a percentage or flat dollar amount applied to the account’s nominal size, checked only at the defined session close. When an account is partially or notionally funded, the NFA’s guidance notes that calculations still reference the nominal size, which changes the effective percentage against actual funds.
Does unrealized profit or loss count toward the end-of-day check?
That depends entirely on the provider’s specific rulebook language, since definitions vary between firms. Always confirm in writing whether the closing snapshot includes open positions marked to market or only realized trades.
What makes an end-of-day drawdown different from a trailing drawdown?
An end-of-day rule checks equity once at the close and ignores intraday swings, while a trailing rule follows the account’s highest intraday equity in real time. We build our funded accounts around the end-of-day model specifically to avoid that real-time chasing effect.
How much does a funded account evaluation cost?
Pricing varies by account size: a 25K Eval is $40, a 50K Eval is $60, and a 100K Eval is $100, all one-time fees. Instant funded and daily payout options are also available at separate price points listed on our site.
