Daily vs Intraday Drawdown in Prop Trading: What Traders Need to Know

Daily drawdown vs intraday drawdown — the practical difference

A daily drawdown rule measures from your equity at one specific reset point (typically end-of-day NY close) to your current equity. An intraday drawdown rule measures from your highest equity at any point in the trading day to your current equity. Two accounts with identical end-of-day P&L can pass a daily drawdown rule and fail an intraday rule on the same set of trades.

The practical implication: intraday rules penalise giving back unrealised profit. If you are up $1,500 on a $25,000 funded account intraday and pull back to $800 still in profit, an intraday drawdown of 5% ($1,250 from peak) has triggered even though you closed the day green. A daily drawdown rule would not care because end-of-day equity is positive.

Which prop firms use which model?

Topstep uses an end-of-day Maximum Allowable Loss based on the account high-water mark — effectively a hybrid that locks the drawdown floor at each end-of-day rather than each peak.

FTMO and FundedNext typically use a Maximum Daily Loss that resets at midnight server time — a daily drawdown rule. The Maximum Loss (overall) rule is a separate static floor.

Apex Trader Funding uses a Trailing Threshold during evaluation that behaves like intraday — the drawdown floor trails your account high. After live funded status it switches to a static floor.

MyFundedFutures, Bulenox, and the newer futures prop firms generally use trailing/intraday models.

How VPS uptime affects each rule type

Both rules are sensitive to uncontrolled losses caused by infrastructure failure — a modem reboot during NFP, a Windows update at the wrong moment, a Wi-Fi drop while in a 1% position. But intraday rules are more sensitive because they punish any drawdown from peak, including drawdowns caused by being unable to exit a position when the market reverses.

A 99.99% SLA trading VPS removes essentially all home-infrastructure failure modes. For traders on intraday drawdown firms (Apex, MyFundedFutures), the VPS is not optional — it is the only way to consistently respect the rule.

Position sizing for daily vs intraday drawdown

A common error is sizing positions only against the daily drawdown limit. On an intraday rule that approach blows out fast: a position large enough to absorb daily-rule volatility creates intraday excursions that breach the trailing limit before the broader daily P&L moves at all.

The practical rule: on intraday-drawdown accounts, size positions so that one full stop-loss does not exceed 25–35% of the intraday drawdown allowance. That sounds conservative until you account for the second open trade you might layer in, the half-pip of slippage on the exit, and the few ticks of adverse excursion before the stop fires.
