Max drawdown is the largest peak-to-trough fall your account may take before the firm closes it. On funded futures accounts it is a fixed dollar buffer, not a percentage: MILTRADERS sets $2,000 on a 50K account, $3,000 on 100K and $4,500 on 150K, measured at the close.
In finance, maximum drawdown measures the largest peak-to-trough decline of an account or portfolio before a new equity high is reached. It quantifies the worst historical loss an investor would have suffered by buying at the top and selling at the bottom of that specific window.
The metric matters because averages hide pain. Two strategies can share the same annual return, yet one may have bled 8% while the other collapsed 35%. The peak-to-valley drop tells you which curve you could actually hold through. Investopedia frames MDD as a downside risk indicator over a specified period (Source: Investopedia, 2026). U.S. regulators stress the same point: gauging downside risk tolerance matters more than chasing headline returns, as Investor.gov explains (Source: U.S. Securities and Exchange Commission, Investor.gov, 2026).
For retail traders, the concept translates directly to account survival. A 50% loss requires a 100% gain just to break even. That asymmetry is why funded programs treat this figure as the single most important guardrail on account equity.
The formula is simple: MDD = (Trough Value − Peak Value) / Peak Value. You track the running peak of the equity curve, then measure the deepest fall from that peak before a new high prints. The result is expressed as a negative percentage or an absolute currency amount.
Step by step, you log every equity update, mark each new high, and compute the distance between each subsequent low and the most recent high. The largest of those distances is your MDD for the observed period. In Excel, a running MAX column paired with a subtraction column does the job.
Two dimensions matter beyond the raw number. Magnitude tells you how deep the wound went. Duration, sometimes called time underwater, tells you how long the account stayed below its prior peak. A shallow but endless drawdown can be more damaging than a sharp one, especially for risk scoring on a funded futures account.
Inside a prop firm, the concept stops being descriptive and becomes prescriptive. It is the maximum equity decline your account can reach before the platform closes it automatically. Cross the line and the funded futures account closes automatically. What counts as crossing depends on the model: an intraday trailing limit reacts to a single tick of unrealized equity, while an end-of-day limit only reads your settled balance at the session close.
Two variants dominate the industry. End-of-day drawdown locks in at session close, giving intraday breathing room. Trailing drawdown follows every new peak equity higher, tightening the leash as you profit. MILTRADERS applies the same end-of-day model with an upward-only trailing lock across all three programs (Zero, Pro, Instant): the liquidation level recalculates once per day and only moves up, never down, until it locks permanently at your starting balance plus $100 — $50,100 on a 50K, $100,100 on a 100K and $150,100 on a 150K.
The hard-stop mechanic is why traders read the rulebook before the chart. A strategy with a healthy historical worst drawdown can still bust an account if the intraday swing pierces the threshold. For a deeper breakdown, see our guide on intraday vs end-of-day drawdown, our list of futures prop firms with end-of-day drawdown, and the pillar article on prop firm rules.
Mathematically, the figure is always negative or zero, because it measures a loss from a prior peak. You will see it quoted as −15% or simply 15%, depending on whether the source keeps the sign or reports the absolute magnitude. Both conventions describe the same reality: money lost from the top.
On a funded account, the number is expressed in dollars rather than percent. A 50K MILTRADERS account defines a fixed $2,000 buffer between your starting equity and the breach level, on ZERO, PRO and INSTANT alike. That buffer is the hard stop your platform enforces in real time.
Think of the value as a countdown, not a score. Every losing trade shortens the distance to termination. Every winning trade, under a trailing model, may also shift the threshold upward and reduce your future room to breathe. Sound risk management means treating the peak-to-trough decline as a budget you spend consciously.
A good max drawdown percentage depends on your instrument, timeframe, and account type. For funded futures accounts, most prop firms set the buffer between 3% and 6% of starting equity. MILTRADERS sits at 4% on a 50K account and 3% on 100K and 150K. The percentage on its own says little: a 3% buffer measured at the close and locked for good is more survivable than a 6% one that trails your unrealized equity tick by tick.
On a personal strategy level, a peak-to-valley drop under 10% is often considered healthy for swing systems. Scalpers usually target under 3%. On funded programs, the number is dictated by the rulebook, not preference. MILTRADERS applies an end-of-day model on all three programs — ZERO, PRO and INSTANT — letting intraday volatility breathe instead of closing a position that finishes the day green.
A 5% drawdown means your account equity has fallen 5% from its highest recorded peak. On a 100K funded futures account, that equals a 5,000 dollar decline from peak equity. The figure is measured against the top of your equity curve, not your starting balance.
The distinction matters. If you grow the account from 100K to 105K, then drop to 99,750, you have posted a 5% peak-to-trough decline, even though you are still profitable on paper. Under a trailing model, that same slip could breach the hard stop. Under end-of-day rules, only the session close counts toward the threshold.
Drawdown quantifies downside risk in a way returns alone cannot. Two strategies with identical annual gains can behave very differently under stress. The shallower peak-to-valley drop is easier to hold and easier to compound. Investors and prop firms use it as a survival metric.
In institutional finance, drawdown feeds ratios like Calmar and Sterling, which weigh return against worst-case loss. For a funded trader, the significance is operational: the maximum equity decline defines the exact dollar buffer between you and account termination. Risk management stops being theoretical when a single breach ends the contract.
Max drawdown in trading measures the largest peak-to-trough decline in account equity over a defined window. Traders use it to gauge strategy pain and firms use it as a hard stop on funded accounts. A backtest showing 8% MDD means the worst historical stretch cost you 8% of equity before recovery.
In Excel, calculate it by tracking a running maximum of your equity curve, then dividing each equity point by that running peak. Subtract one, and the most negative result is your worst drawdown. The formula uses MAX with an expanding range, paired with MIN on the resulting percentage series.
On most funded futures accounts, breaching the threshold ends the account permanently. There is no reset once the hard stop triggers. Some firms allow you to purchase a new evaluation or instant account at standard pricing. Review the MILTRADERS rulebook before sizing positions.
Trailing drawdown adjusts upward with every new peak equity, tightening the buffer as you profit. End-of-day drawdown only updates at session close, giving you intraday room to swing. Trailing models reward locking gains fast; end-of-day models reward disciplined session management.
On funded accounts, the threshold typically does not reset. Once your buffer shrinks under a trailing model, it stays shrunk unless the rules specify otherwise. MILTRADERS is the exception, on all three programs: once your closed balance has banked the max drawdown +$100, the liquidation level freezes for good at your starting balance +$100 — $50,100, $100,100 or $150,100 — and never moves again.
Understanding max drawdown transforms it from a mysterious rule into a manageable budget. Track your peak equity, respect the buffer, and size trades against the distance to the hard stop. MILTRADERS publishes clear thresholds for each program so you know exactly where the line sits. Read the rules once, then trade with intention.
MILTRADERS funds international retail futures traders through three transparent one-time-fee programs: ZERO, PRO, and INSTANT. Explore the framework in our guide on prop firm rules explained to see how thresholds, splits, and payout mechanics fit together before choosing your account size.
