Prop Firm Rules Explained: Targets, Daily Loss, Drawdown, Minimum Days
Every prop firm publishes the same four headline rules, and most traders still fail on one of them within two weeks. The difference between passing and paying again is knowing exactly what each rule measures, in dollars, before you place a trade. This guide converts a typical rulebook into numbers on a $100,000 account.
Profit target: the visible goal
The profit target is the percentage gain that completes a phase. A typical two-step firm asks for 8% in phase one and 5% in phase two — $8,000 and then $5,000 on a $100,000 account. Most one-step challenges ask for around 10% once.
Many firms now sell challenges without time limits, though some still impose 30 or 60 calendar days. A deadline matters because it forces a minimum pace, and pace is set by risk per trade.
The target itself is the least dangerous rule, because missing it today costs nothing. To see it as workload rather than a wall, break it into trades: at $1,000 risk per trade and winners twice your risk, ten trades at a 60% win rate produce 6 × $2,000 − 4 × $1,000 = $8,000. The loss rules below are what actually end attempts.
Daily loss limit: the rule that ends most attempts
The daily loss limit caps how much you may lose in a single day, commonly 4% to 5%. On $100,000 with a 5% limit, your equity may not drop more than $5,000 below the day's starting point. Firms differ on whether that anchor is the day's opening balance or opening equity, so confirm which applies before you hold positions overnight.
The limit counts floating losses, which is where attempts die. Suppose you are down $3,800 on the day and you open a 2-lot position on a major currency pair, where each pip moves your equity by about $20. Your remaining buffer is $1,200, which is exactly 60 pips. One ordinary volatility spike can cover that distance in minutes.
The same buffer traded at 0.5 lots gives you 240 pips of room. The market did not change between those two sentences; the position size did. Near the limit, sizing is the only variable you control.
Notice the trap in that example: at down $3,800, many traders increase size to win the day back. That is the exact geometry of a blown account — the closer you are to the line, the smaller the move that ends everything, precisely when your size is growing.
Max drawdown: the floor under the whole attempt
Max drawdown caps total loss from the starting balance, commonly 10%. On $100,000 the floor is $90,000: if equity touches $89,999 at any point in the attempt, it is over, regardless of how strong the surrounding weeks were.
The definition of the floor matters as much as the number. A static floor stays at $90,000 forever; a trailing floor rises as your equity rises; end-of-day variants move only on closing balances. The differences are large enough to fail identical trades under different firms, and they get a full walkthrough in static vs trailing vs end-of-day drawdown.
Budget the allowance like capital. With a $10,000 total allowance, $1,000 risk per trade means ten consecutive full losses end the attempt; at $500 risk it takes twenty. Many traders pick their risk per trade by deciding how long a losing streak the attempt should be able to survive.
Minimum trading days: why speed does not pay
Minimum trading days require activity on a set number of separate days, commonly 3 to 5 per phase. One oversized lucky day cannot complete a phase on its own, which is the point: the firm wants evidence of repeatability, not variance.
The rule interacts with the target. An $8,000 target across a 4-day minimum implies a plan with a realistic daily expectation, not one all-in trade. Note also that a trading day usually means a day with at least one executed position, measured in the firm's platform time zone — an easy detail to miss if you trade late sessions and your midnight is not theirs.
The rules hiding in the FAQ
The four headline rules are not the whole contract. Common extras include consistency clauses that cap your best day as a share of total profit, restrictions on trading through major scheduled news, weekend holding bans, inactivity limits, and prohibited tactics such as copying trades between accounts.
These are the rules that surprise people at payout time, because breaking them often does not fail the account in real time — it surfaces later, during review. Consistency rules and news trading restrictions are worth reading before you pay, not after a withdrawal is refused.
Turn the rulebook into dollars before you start
Percentages hide risk; dollars reveal it. Before an attempt, write out the firm's exact rules as amounts on your account size and what one breach costs you.
| Rule | Typical setting | On $100,000 | One breach means |
|---|---|---|---|
| Profit target | 8%, then 5% | Reach $108,000, then $105,000 | Nothing lost, phase incomplete |
| Daily loss limit | 5% | Never −$5,000 against the day's start | Attempt over |
| Max drawdown | 10% | Equity floor at $90,000 | Attempt over |
| Minimum trading days | 3–5 | Profit spread across sessions | Pass withheld until met |
Then rehearse against those numbers until respecting them is automatic. Rules you can recite from memory under pressure are rules you keep; rules you half-remember are the ones that end attempts on an otherwise ordinary Tuesday.
