Challenge design and trading rules
Designing evaluations: loss limits, profit targets, trading days, consistency, behaviour rules, and changing rules fairly.
How do I design a prop firm challenge?
Start with the trader you want to attract, then set account sizes, a profit target, a daily loss limit, a maximum loss limit and minimum trading days. Add behaviour rules only where they protect the firm, model the payout cost, and write every rule so a trader can tell exactly when it applies.
Which rules should a prop firm challenge have?
Most challenges combine a profit target, a daily loss limit, a maximum loss limit and minimum trading days. Common additions are a trailing drawdown, a consistency rule, lot size or position limits, weekend holding restrictions and news trading restrictions. Fewer, clearer rules usually produce fewer disputes.
What is a daily loss limit?
A daily loss limit is the maximum a trader may lose within one trading day, usually a percentage of the starting balance or of the day's opening balance or equity. Crossing it ends the evaluation. It stops a trader from losing a large share of the account in a single bad session.
How should a daily loss limit be calculated?
Measure it on equity, so open losses count, against a daily reference set at a fixed reset time. The fairest and safest reference is the higher of balance and equity at the reset, which stops a floating loss carried overnight from giving the trader a fresh allowance measured from an already depressed level.
What is a maximum loss limit?
A maximum loss limit is the overall loss an account may never exceed, usually a percentage below the starting balance. With a static limit, a $100,000 account with a 10% limit can never fall below $90,000. Crossing it ends the account, whatever happened on any single day.
What is the difference between static and trailing drawdown?
Static drawdown measures loss from a fixed point, usually the starting balance, so the floor never moves. Trailing drawdown measures loss from the highest equity reached, so the floor rises as the account makes new peaks. Trailing is stricter, because profits raise the floor.
What is a trailing drawdown that locks at break-even?
It is a trailing floor that follows peak equity upward until it reaches the starting balance (break-even), then stops moving. After that the trader cannot lose the original balance, and gains above it are protected from the trailing rule. It is a common compromise between static and pure trailing drawdown.
What is a profit target, and how high should it be?
A profit target is the gain, as a percentage of the starting balance, that a trader must reach to pass. Common targets are around 8% to 10% for one-step and first phases, and around 5% for second phases. The right level balances your payout cost against whether skilled traders can realistically pass.
What are minimum trading days?
Minimum trading days require a trader to place trades on a set number of different days before they can pass or request a payout. They discourage passing with one lucky trade and give the firm more evidence of skill. Common minimums range from a few days up to around ten.
Should a challenge have a time limit?
Time limits are less common than they were, because traders dislike them and they encourage over-risking near the deadline. Many firms now offer unlimited time or sell no time limit as an add-on. If you use one, make it generous and decide what happens to accounts that reach it in profit.
What is a consistency rule?
A consistency rule stops one exceptional day from making up most of a trader's profit. A typical version says no single day's profit may exceed a set percentage, often 30% to 50%, of total profit. It discourages passing on one high-risk trade and is common before payouts.
Should a prop firm allow news trading?
Policies vary. Some firms allow news trading freely, some restrict opening or closing trades within a few minutes of high-impact releases, and some sell it as an add-on. Restrictions protect against spikes and gaps, but they require an economic calendar and are a common source of disputes.
Should a prop firm allow positions to be held over the weekend?
Many firms allow weekend holding on swing-style accounts and ban it on intraday accounts, sometimes selling it as an add-on. Weekend gaps can move prices past stops, so holding raises risk. If you ban it, set a clear Friday cutoff time and say what happens to open positions.
Should a prop firm allow overnight positions?
Most CFD prop firms allow overnight positions, because many strategies hold for more than a day. Some intraday-focused programmes require positions to be closed before the end of the day. If you restrict it, define the cutoff time clearly and decide how open positions are handled.
What leverage should a prop firm offer?
CFD prop firms commonly offer leverage between about 1:30 and 1:100 on forex, often lower on indices, metals and crypto. Higher leverage lets traders take larger positions relative to equity and increases the chance of large swings. Many firms set leverage by asset class.
What maximum lot size should a challenge allow?
Set maximum lot size relative to account size and your loss limits, so a single order cannot risk an extreme share of the account. Many firms cap lots per order or total open lots per account. The cap should still allow normal position sizing for the strategies you want to attract.
What is a maximum open positions rule?
A maximum open positions rule limits how many positions an account can hold at once, for example five. It prevents a trader from spreading risk across many simultaneous positions that together exceed sensible exposure, and limits some grid and martingale strategies.
What is a minimum holding time rule, and why use one?
A minimum holding time rule requires trades to stay open for at least a set time, such as 60 seconds. It discourages tick scalping and latency strategies that exploit simulated execution rather than market skill. Firms usually flag or exclude such trades rather than ending the account immediately.
Should a prop firm restrict trading hours?
Trading hours restrictions are useful for specific programmes, for example to avoid illiquid periods or rollover spreads, or to keep intraday accounts within a session. For most general challenges they are not needed. If you use them, state the window in UTC and say what happens to orders outside it.
Should a prop firm allow hedging within one account?
Hedging within one account means holding a long and a short on the same instrument at once. Some firms allow it, since it is a legitimate risk tool; others ban it because it can be used to game rules or offers no real exposure. Hedging across different accounts is a separate and usually prohibited issue.
Which instruments should a challenge allow?
Allow instruments your audience trades and your price feed covers well: major forex pairs, gold, main stock indices and often oil and Bitcoin. Restrict thinly traded or very volatile instruments, or put them on a separate account type with tighter leverage.
Which account sizes should a new prop firm offer?
Most firms offer a ladder such as $5,000, $10,000, $25,000, $50,000, $100,000 and sometimes $200,000. A new firm can start with two or three sizes to test demand, adding more later. Price each size on its own payout risk.
How do I make a challenge fair to traders and still profitable?
Use rules that skilled traders can meet with sensible risk, define them precisely, enforce them identically and immediately, and protect profitability through pricing, payout terms and abuse controls rather than hidden traps. Fair challenges build reputation, which lowers acquisition cost over time.
Should a daily loss limit be measured on balance or equity?
Equity is more protective because it includes open losses: a trader cannot sit on a large floating loss without consequence. Balance-based limits only count closed trades. Most firms measure the limit on equity, and the best approach measures equity against a day reference that does not reward overnight floating losses.
What happens when a trader breaches a rule?
For loss limits, the account normally ends immediately: trading stops, the account is marked as failed and the trader is told which rule was broken. For order-level rules, the order is usually refused instead. For behaviour rules, the firm may flag the account for review rather than end it.
Should a rule violation end the account or only reject the order?
Use account-ending breaches for loss limits, where the damage has already happened, and order rejection for rules that can be prevented before the trade, such as lot size, instruments or position count. Use flags for behaviours that need a human decision. Matching the action to the rule feels fairer to traders.
What is an inactivity rule?
An inactivity rule ends or flags an account that has not traded for a set number of days, for example 30. It clears abandoned accounts, keeps funded accounts active, and replaces a hard time limit with a softer requirement. The period and the consequence should be stated clearly.
How do I change challenge rules without affecting existing traders?
Apply new rules only to accounts sold after the change, and leave existing accounts on the rules they bought. The cleanest way is a platform that versions rule sets and freezes each account to the version in force when it was created, so a change cannot reach running accounts.
How should a prop firm communicate rule changes to traders?
Announce changes in advance, state exactly what changes and from which date, confirm that existing accounts keep their current rules, and update the rules page with the version and date. Explain the reason briefly. Surprises are what turn a rule change into a reputation problem.
How do I write rules that traders cannot dispute?
Define every term (equity, trading day, reset time), give the exact calculation, include a worked example, state the consequence of breaking each rule, and make the platform enforce the rules exactly as written. Show traders their live position against each rule so nothing comes as a surprise.
What are the most common rule disputes between traders and prop firms?
The most common disputes involve how daily loss is calculated (balance or equity, reset time), breaches caused by price spikes or wide spreads, consistency rules blocking payouts, prohibited strategy decisions, and rules that changed after purchase. Most are avoided by precise definitions and transparent data.
What is the difference between a breach and a flag?
A breach ends the account because a rule was broken. A flag records that a rule was tripped without ending the account, so the firm can review it later, typically before a payout. Flags suit behaviours that need judgement, such as very short trades, where context matters.
Should I copy another prop firm's rules?
Using established firms' rules as a starting point is reasonable, because traders recognise them. Copying them exactly without their pricing, audience and payout data is risky, since rules only work together with pricing and payout terms. Adapt them, model them, and make sure your platform calculates them the same way.
