# Daily Loss Limit > A rule ending or suspending an account when losses within a single trading day exceed a set amount, assessed against a baseline that resets each day rather than against the account's overall decline. - Canonical: https://hadalinstruments.com/glossary/daily-loss-limit/ - Term set: https://hadalinstruments.com/glossary/ --- A daily loss limit ends or suspends an account when the losses inside a single trading day exceed a set amount. It is among the rules quoted most prominently in an evaluation and among the easiest to misread, because the headline figure is simple while everything that decides outcomes sits in the definitions underneath it. Three details do the work. The first is the **baseline**: the limit is measured from a reference point set at the start of each day, and the two conventions in circulation are the day's opening balance and the day's opening equity. They agree whenever you start the day flat and diverge whenever you do not — under an equity baseline a position carried overnight arrives with its floating loss already counted, and under a balance baseline it does not. The second is **what is tested**. A limit assessed on closed trades can only be breached by realised losses; one assessed on floating equity is tested continuously against the equity path, which means an unrealised excursion that later recovers in full can still have crossed the floor while it was open. The third is the **reset**: a time, in a timezone, that divides the record into independent assessments and against which a position held across the boundary is measured twice, under two different baselines. None of these is derivable from the number. A trader who knows their limit is a certain amount, and nothing else about it, does not know the distance to it — and distance to the floor, not the size of the allowance, is the quantity that governs the next order. That distance also does not carry over: yesterday's remaining room is not information about today's, which makes the daily limit different in kind from an overall [drawdown](/glossary/drawdown/) allowance that accumulates across the whole evaluation. Because the two rules are assessed independently, either can end an account without the other coming close, and which one binds changes as circumstances do. On a fresh account the overall floor sits a full allowance below you while the daily one resets each morning; after a decline the overall floor can be the nearer of the two. The operative quantity is the smaller of the two distances, restated whenever either moves — which under a [trailing drawdown](/glossary/trailing-drawdown/) means after every new high on whichever basis that rule samples, equity or closing balance. The [trailing drawdown calculator](/tools/trailing-drawdown-calculator/) computes the distance to a ratcheting floor at your position size, and the day-scoped rule pointing the other way — capping what one day may contribute rather than take away — is the [consistency rule](/glossary/consistency-rule/). Where an evaluation has already ended and the arithmetic behind it needs reconstructing from your own account record, that is [Prop-Breach Forensics](/assays/#prop-breach-forensics). ## Commonly confused with Neighbouring concepts that get used interchangeably, and the distinction that actually separates them. - **[Maximum drawdown limit](https://hadalinstruments.com/glossary/drawdown/)** — A drawdown limit measures the account's total decline from a peak, accumulated across the whole evaluation. A daily loss limit measures one day in isolation against a baseline that resets. An account can be comfortably inside its overall drawdown allowance and still end on a single day, and it can grind out many small losing days without either rule noticing. - **[Trailing drawdown](https://hadalinstruments.com/glossary/trailing-drawdown/)** — Both involve a floor and both can end an account, but they are computed from different reference points. A trailing floor is anchored to the account's high-water mark and ratchets up permanently — though what sets that mark differs, equity including open trades under an intraday rule and a closed daily balance under an end-of-day one. A daily limit is anchored to a baseline that resets, so yesterday's breach distance tells you nothing about today's. - **[Consistency rule](https://hadalinstruments.com/glossary/consistency-rule/)** — Day-scoped like this one, and pointing the other way. A daily loss limit caps what one day may take away; a consistency rule caps what one day may contribute. They are assessed separately and a record can be caught by either without approaching the other. - **A stop loss** — A stop loss is a decision you make about a position. A daily loss limit is a condition imposed on your account, enforced by someone else, and typically applied to the whole account rather than to any single trade. Sizing a stop without knowing the distance to the daily limit is sizing against the wrong constraint. ## How to measure it in your own data A definition you cannot test is a definition you have to take on trust. This is the shortest honest route from the concept to a number you computed yourself. - **Records you need** — The rule text naming the baseline and when it resets, plus your intraday equity — not just closing balances — at the granularity the rule uses. Where the rule tests floating positions, closed-trade records cannot reconstruct the breach. - **What you compute** — Establish the day's baseline as the rule defines it, subtract the allowance to get the day's floor, and track the distance from your current equity to that floor. Restate it after every reset, because the distance does not carry over. - **What the answer tells you** — Two details dominate. Whether the baseline is the day's opening balance or the day's opening equity changes the floor whenever positions are held through the reset, and whether the limit is tested on closed trades or on floating equity decides whether an open position can breach it before you have taken any loss at all. Where the rule tests floating equity, an unrealised excursion that fully recovers can still have ended the account on the way through. ## Questions and answers ### What is the daily loss limit measured from? From a baseline the rule sets at the start of each trading day, which is the detail worth reading carefully. The two common conventions are the day's opening balance and the day's opening equity, and they differ whenever a position is held through the reset — under one an open floating loss is already counted against you, under the other it is not. ### Can an open position breach a daily loss limit? Where the rule tests floating equity rather than closed trades, yes — and it can do so on a position that later recovers completely. The test is applied continuously to the equity path, so an excursion that never became a realised loss can still have crossed the floor while it was open. Whether your rule works that way is a property of its text. ### When does the limit reset? At a time the rule specifies, in a timezone the rule specifies, and neither is safe to assume. The reset defines the boundary between two independent assessments, so a position held across it is assessed under one baseline before and a different one after. ### Does a daily loss limit interact with the overall drawdown rule? The daily limit and the overall drawdown rule are assessed independently and either can end an account on its own. That means the binding constraint changes with circumstances: on a fresh account the overall floor sits a full allowance away while the daily one resets each morning, and after a decline the overall floor can be the nearer of the two. The distance that matters is the smaller of them, restated as both move. ## If this has already cost you If a day ended an evaluation, which baseline the limit was measured from and whether floating equity was tested are answerable from your own account record. - [Prop-Breach Forensics](https://hadalinstruments.com/assays/#prop-breach-forensics) “Why did my prop evaluation actually fail?” Will not establish: Whether the firm’s rules are fair, or whether you would have passed with different luck. It reconstructs what happened; it does not adjudicate the firm. - [Payout-Denial Recompute](https://hadalinstruments.com/assays/#payout-denial-recompute) “Does the arithmetic behind my denied payout actually hold?” Will not establish: Whether the firm must pay. A recomputation shows whether the stated condition was met under the stated rules; contract interpretation and enforcement belong to the firm, a regulator where one exists, or your own adviser — armed with arithmetic instead of assertion. Intake is not open yet, so none of these can be commissioned today. They are listed here so you know the measurement exists and what it would and would not settle — the [launch list](https://hadalinstruments.com/pricing/#waitlist) hears first. ## Work it out yourself Free calculators that take this concept as an input. Each shows its working, so the number it gives you can be checked rather than taken on trust. - [Position size calculator](https://hadalinstruments.com/tools/position-size-calculator/) Lots and units, costs included · The textbook figure and its oversize - [Prop evaluation survivor](https://hadalinstruments.com/tools/prop-evaluation-survivor/) Pass, breach or expiry, across your sample’s range · Which rule bound on the breached paths ## Related terms Derived from the links this entry makes and the entries that link back to it. - [Consistency Rule](https://hadalinstruments.com/glossary/consistency-rule/) An evaluation rule capping the share of profit that any single trading day may account for, so that a target reached by one outsized day does not qualify even when the total is met. - [Drawdown](https://hadalinstruments.com/glossary/drawdown/) The decline of an equity curve from its running peak, measured until a new peak is made; the maximum drawdown is the deepest such decline anywhere in the record. - [Hard Breach](https://hadalinstruments.com/glossary/hard-breach/) A rule breach whose stated consequence is the end of the account: the condition fires, the account is closed or its open positions are liquidated, and the programme is over subject to whatever the agreement says follows. - [Trailing Drawdown](https://hadalinstruments.com/glossary/trailing-drawdown/) A drawdown limit measured from an account's high-water mark rather than its starting balance, so that the termination floor rises as the account makes new highs and never retreats. ## In the research Daily Loss Limit comes up in two research notes on this site. - [What a funded trading account breach means](https://hadalinstruments.com/research/what-a-funded-trading-account-breach-means/) Not a data breach. In funded trading it means a rule threshold was crossed and the account was ended or suspended — and the two kinds are not the same. - [What can a trading statement prove?](https://hadalinstruments.com/research/what-can-a-trading-statement-prove/) Its own arithmetic and the facts inside the file — the closed ledger — but never the market around your fills, a quote's honesty, or anyone's intent. ## Cite This Definition APA BibTeX HTML Hadal Instruments.
