A funded-account challenge looks simple on the sales page: hit a profit target, don't break the rules, get access to a larger account. In practice, most failed challenges don't fail because the trader never reached the target. They fail because a rule was misunderstood — a daily loss limit that included open trades, a drawdown that trailed the equity peak, or a news restriction nobody read.
This guide walks through the rules you'll meet most often, how each one is usually calculated, and what it means for the size of every trade you take. Rules differ between firms and change over time, so treat this as a map for reading your own firm's rulebook, not a replacement for it.
The rules you will see in almost every challenge
| Rule | Typical form | What it means for you |
|---|---|---|
| Profit target | A percentage of the starting balance | The finish line. It says nothing about how fast you should get there. |
| Maximum daily loss | A percentage of the initial balance, or of the day's opening balance or equity | Your hard limit for one trading day, often including floating losses. |
| Maximum overall loss | Static (fixed floor) or trailing (moves up with your peak) | The account's absolute floor. Touch it once and the challenge ends. |
| Minimum trading days | A number of days with at least one trade | Stops anyone from passing on one lucky trade. |
| Time limit | Some firms have one, many have dropped it | If present, it changes how much pressure you feel near the end. |
| Trading restrictions | News windows, weekend holding, certain EA behaviours | Breaking these can void a pass even when the numbers look fine. |
Notice that only one of these rules is about making money. The rest are about not losing too much, too fast. That's the real test.
Daily loss: read the calculation, not just the percentage
"5% daily loss" can mean very different things depending on two details:
- What the percentage is measured from. Some firms use the initial account size; others use the balance (or equity, whichever is higher) at the start of each day — usually reset at a specific server time, not midnight in your time zone.
- Whether floating P&L counts. Many firms check equity in real time. An open trade that is down $3,000 counts toward the limit even if you planned to hold it until it recovers.
Worked example on a $100,000 account with a 5% daily limit measured from the initial balance:
- Daily limit in money: $5,000.
- You start the day with a balance of $102,000, so the lowest equity you can touch today is $97,000.
- You close a $2,000 loss, then hold a trade that is floating $3,100 down. Equity is $96,900 — the rule is broken, even if that trade later closes in profit.
If the limit were measured from the day's starting balance instead, the floor that day would be $102,000 minus 5% of $102,000, or $96,900. Differences this small matter when you trade close to the edge.
Static vs trailing drawdown
A static maximum loss sets a fixed floor. On a $100,000 account with a 10% limit, the floor is $90,000 for the life of the account, no matter how much you make.
A trailing maximum loss follows your highest balance or equity. With a 6% trailing limit, the floor starts at $94,000. If your equity peaks at $104,000, the floor rises to $98,000. Some firms stop trailing once the floor reaches the starting balance; others never stop. Some trail on closed balance, others on intraday equity peaks — which means unrealised profit you later gave back can still have raised your floor.
Trailing drawdown punishes a common habit: letting a winning trade run up, then watching it reverse. You can close the trade flat and still have lost room. If your firm trails on equity, consider partial profit-taking or tighter management of open winners.
The drawdown calculator shows how quickly a losing streak eats into these floors.
Turning the rules into a risk-per-trade number
The cleanest approach is to work backwards from the daily limit:
- Decide how many full losses in a row you want to survive in one day — say four.
- Keep a buffer for slippage and spread, for example 20% of the limit.
- Divide what's left by the number of losses.
With a $5,000 daily limit: $5,000 × 0.8 = $4,000, and $4,000 ÷ 4 = $1,000, or 1% per trade. If you'd rather survive six losses, the same arithmetic gives about 0.67%.
Then check the overall limit: at that risk, how many consecutive losses take you to the static or trailing floor? If the answer is uncomfortably small, lower the risk. The prop firm calculator does this arithmetic for you, and the position size calculator turns the percentage into a lot size for your stop distance.
For the reasoning behind fixed-percentage risk, see position sizing and the 1% rule.
The fine print that ends challenges
- News trading. Some firms forbid opening or closing trades within a window around high-impact releases; others allow it during the evaluation but not on funded accounts.
- Weekend and overnight holding. Positions held through the weekend gap may be prohibited or force-closed.
- Expert Advisors. Many firms allow EAs but ban specific behaviours: tick scalping, latency arbitrage, copying identical trades across many accounts, or running an off-the-shelf EA that hundreds of other traders also use. Read the EA section before you deploy anything.
- Consistency rules. Some firms cap how much of your total profit can come from a single day or a single trade.
- Lot and leverage limits. Leverage on challenge accounts may be lower than you're used to. That changes margin, not risk — but it can stop an order from opening at all.
Automating the guard rails
If you run an EA on a challenge account, put the rules into the code, not just into your head: a daily equity floor that closes positions and stops trading, a maximum number of trades per day, and a block outside the sessions you choose. Our MQL5 Expert Advisor risk checklist covers how to build each of these, and the market hours tool helps you pick sensible session windows.

Describe your challenge rules in plain English — "stop trading for the day if equity drops 4% below the day's starting balance, risk 0.75% per trade, no new trades on Friday after 18:00 server time" — and Edgoro drafts an MT5 Expert Advisor or a TradingView strategy that follows them. Test it on a demo or trial account before you trust it with a real challenge. Start with three free generations.
Trading involves substantial risk of loss. Passing a challenge is never guaranteed, and nothing here is investment advice.
