How to Track Drawdown Across Prop Firm Rules

In short. Prop firms enforce two separate drawdown limits: a daily limit that resets each trading day and a maximum limit that follows the account for the life of the challenge. Breaching either one ends the challenge regardless of overall profit, so tracking both in a trading journal, not just your account balance, is what keeps a payout within reach.

Most traders who fail a prop firm challenge do not fail because their strategy stopped working. They fail because they were tracking the wrong number. A trader can be net profitable for the month and still get disqualified on a single bad afternoon, because daily drawdown and maximum drawdown are measured differently, reset on different schedules, and often calculated from different account values than the ones shown on the trading platform.

This guide breaks down how daily and maximum drawdown actually work across prop firm rule sets, where the two limits diverge, and how to track both against your real trading activity instead of guessing from a balance figure.

Daily drawdown: a limit that resets every trading day

Daily drawdown caps how much an account can lose within a single trading day, measured from a reference point set at the start of that day, usually the balance or equity at a fixed reset time (commonly midnight server time, though some firms use 5 p.m. EST to align with the futures session rollover).

If a firm sets a 5 percent daily drawdown limit on a 100,000 account, the trader has a 5,000 budget for that day. Once losses reach that threshold, either from closed trades, open floating losses, or both, the account is locked out or disqualified, depending on the firm's rules.

The part traders get wrong most often: the reset is to the starting balance of the day, not to the previous day's closing equity after a withdrawal or an internal adjustment. Two accounts that both start the day at 100,000 can have very different remaining daily budgets if one carried open positions with unrealized losses into the new session.

Actual limits vary by firm and by challenge type. FTMO, one of the larger firms in this space, publishes a 5 percent maximum daily loss on its two-step challenge and 3 percent on its one-step challenge, calculated against equity rather than closed-trade balance alone, so an open position counts against the limit the moment it moves against the trader (FTMO Academy: Maximum Daily Loss; FTMO Trading Objectives). Always confirm the exact figure and calculation method in the specific firm's own rules document rather than assuming one firm's setup applies to another.

Maximum drawdown: a limit that follows the whole challenge

Maximum drawdown caps the total loss an account can sustain across the entire evaluation, from the initial balance down to a floor the account can never cross. Unlike daily drawdown, it does not reset. Every losing day chips away at the same ceiling until the challenge ends or the trader passes to a funded stage.

A 10 percent maximum drawdown on a 100,000 account sets a hard floor at 90,000. It does not matter whether that 10,000 loss happened over one bad day or accumulated slowly across six weeks. Once equity touches the floor, the account is closed.

FTMO's version of this rule is a useful concrete example because it is publicly documented in detail: the maximum loss limit is recalculated every day from the highest end-of-day balance the account has ever reached (or the initial capital, whichever is higher), it moves up whenever a new balance high is set, and it never moves back down after a losing day (FTMO Academy: Maximum Loss). That is a specific, firm-defined mechanic, not a universal standard, and it should not be assumed to match every other firm's rules.

Static vs trailing maximum drawdown

This is where most confusion between firms comes from, and it is worth treating as its own decision point before choosing a challenge.

• Static maximum drawdown: the floor is fixed at initial balance minus the drawdown percentage, and it never moves, even as the account grows. A 100,000 account with a 10 percent static max drawdown always has its floor at 90,000, whether the account is worth 100,000 or 130,000.
• Trailing maximum drawdown: the floor moves up as the account's equity reaches new highs, tracking a fixed distance below the highest equity point ever recorded (not below the current balance). A 100,000 account with a 10 percent trailing max drawdown that grows to 120,000 now has its floor at 108,000, even if the account later drops back toward 110,000.

Trailing drawdown is significantly less forgiving during a strong run of profitable days, because every new equity high immediately tightens the floor. A trader who does not track this in real time can be surprised by how little room is left after a good week, not a bad one.

Important. Some firms calculate trailing drawdown from the highest closed-trade equity, others from the highest intraday floating equity, including unrealized profit on open positions. That distinction alone can change the effective floor by a meaningful margin, and it is rarely explained clearly in marketing pages. Always check it in the actual rules document, not the sales page.

Balance-based vs equity-based calculation

Beyond static and trailing, firms differ on which number they measure against: account balance (only realized profit and loss from closed trades) or account equity (balance plus unrealized profit and loss on open positions).

Equity-based rules count floating losses toward both daily and maximum drawdown the moment they happen, even before a position is closed. A trader holding a losing position overnight or through a volatile session can breach a limit purely on unrealized movement, then have the trade recover minutes later, after the account has already been disqualified.

Balance-based rules only count drawdown once a trade closes, which gives more room for open positions to fluctuate, but can also mask how close an account really is to a breach until the position is closed and the loss is locked in.

MetaTrader itself, the platform most prop firms build their evaluations on, defines the two terms precisely: balance reflects only the results of closed trades, while equity is balance adjusted in real time for the floating profit or loss of any open positions (MQL5 documentation: Account Properties). A firm's drawdown rule inherits that distinction directly. Equity-based rules pull in that real-time floating figure; balance-based rules ignore it until a position closes.

Most prop firm challenges run on MetaTrader 5, and the rule engine reads directly from that account, not from a separate dashboard. If the trading account is connected through the MetaTrader 5 integration (see also: how to connect MetaTrader 5 to BitStat), both closed and floating figures can be logged automatically instead of copied by hand after each session.

Daily drawdown vs maximum drawdown at a glance

Tracking both limits in a trading journal

A live balance figure on the trading platform does not show how much of either budget has actually been used. It shows where the account is right now, not how close it is to a rule breach that resets on a different schedule than the one the platform displays by default.

The example below illustrates why the two numbers need to be tracked separately rather than inferred from the account balance alone. Daily drawdown usage swings up and down with each session, sometimes touching a large share of the daily limit even on a day that ends flat. Cumulative drawdown against the maximum limit moves in one direction only, building up gradually across sessions that each looked manageable on their own.

In a trading journal, that means logging, for every session: the daily loss as a percentage of the daily limit, and the running cumulative loss as a percentage of the maximum limit, calculated from whichever reference point the firm actually uses (static initial balance or trailing high-water mark). Tracking both side by side, rather than only the account balance, is what turns drawdown from an abstract rule into a number that shapes position sizing decisions before a limit is close, not after it is breached.

Building a risk budget around both limits

A workable approach is to size each trade against a fraction of the daily limit, not the maximum limit, since the daily limit is the one that resets and therefore the one that governs how much risk is available on any given session.

If the daily drawdown limit is 5,000 and a trader wants to survive at least four consecutive losing trades in a single session before hitting that ceiling, each trade's maximum loss should be budgeted at roughly 1,000 to 1,250, not the full 5,000 in one or two trades. That buffer matters because a single oversized loss can consume most of a day's budget and force the trader to either stop trading for the rest of the session or take on outsized risk trying to recover it within the same day.

The maximum drawdown limit then acts as a slower-moving ceiling on how many bad days, weeks, or losing streaks the strategy can absorb before the account is closed. A strategy with a realistic historical maximum drawdown of 8 percent has very little margin left under a 10 percent firm limit, even if its average trade is profitable over a longer sample.

One-step vs two-step challenges change how drawdown pressure builds

The evaluation structure a firm uses changes how much room there actually is under the drawdown limits, even when the stated percentages look identical on paper.

A two-step challenge (a phase 1 profit target, then a phase 2 confirmation phase, then funding) usually spreads the same profit target across two separate evaluation windows, which gives more sessions to absorb a losing streak without pushing daily drawdown close to its limit on any single day. A one-step challenge compresses the same target into a single phase, which tends to push traders toward larger position sizes to hit the target within the available time, and larger positions consume a bigger share of the daily limit on any losing session.

Two accounts with an identical 5 percent daily and 10 percent maximum drawdown rule are not carrying the same practical risk if one is a one-step challenge with a tight time limit and the other is an untimed two-step evaluation. The rule text is the same; the pressure it creates on position sizing is not, and that pressure is exactly what shows up as drawdown usage in the journal, not in the rules document.

Drawdown mistakes that end challenges early

• Sizing against the maximum limit instead of the daily limit. A position sized to survive the full account drawdown can still blow through the daily limit in a single session.
• Ignoring open floating losses under equity-based rules. A position that is down 3 percent unrealized already counts against the limit the moment it happens, not when it is closed.
• Not confirming the daily reset time. Trading past a firm's reset boundary without accounting for it can mean two sessions' worth of risk gets logged as one, or vice versa.
• Confusing trailing drawdown with static drawdown after a strong week. A profitable run tightens a trailing floor even though the account balance looks safer than ever.
• Treating a flat day as a safe day. A day that ends near breakeven can still have touched a large share of the daily limit intraday, which a trading journal captures and a closing balance does not.

Trade with the rules in view, not just the balance

Drawdown rules are not a formality attached to a prop firm challenge; they are the actual constraint the strategy has to survive. Reading the rules document once at signup and then trading against the account balance for the rest of the challenge is how traders get disqualified on days that felt, in the moment, perfectly ordinary. BitStat's solutions for prop traders are built around exactly this gap between what the platform balance shows and what the rules actually measure.

This article is for educational purposes only and is not financial or investment advice. Trading with leverage carries a high risk of loss, and prop firm challenges add rule-based risk on top of market risk. Past performance does not guarantee future results.

Track daily and cumulative drawdown against your actual limits, session by session, in the BitStat trading journal, instead of relying on a balance figure that does not show either budget.
