Key takeaways
- Evaluations are usually lost on the risk rules: the daily loss limit and the maximum or trailing drawdown.
- Work backwards from the drawdown: decide how many losing trades in a row you must be able to survive, then size from that.
- A trailing drawdown follows your highest balance, so giving back open or banked profit eats into it.
- Set your own daily stop well inside the firm's limit, cap your trades per day, and plan around scheduled news.
How prop firm evaluations work
Most evaluations, often called challenges or combines, give you an account size and a set of rules. You pass by reaching a profit target without breaking any rule. The details vary a lot between firms, so read your firm's rulebook carefully, but the common ones are:
- Profit target: the amount you need to make to pass.
- Daily loss limit: the most you can lose in a single day.
- Maximum drawdown: the most the account can fall overall. Many firms use a trailing drawdown, which follows your highest balance up.
- Consistency rules: limits on how much of your profit can come from a single day.
- Minimum trading days and restrictions around certain news events.
It's also worth knowing that many firms run their evaluation and "funded" accounts on simulated capital, with payouts governed by their own terms. Read how payouts work before you start.
Why most people fail
1. Sizing up to hit the target quickly
The target feels far away, so position size goes up. A few losses at that size and the drawdown is gone. The maths is brutal: on an account with a $2,000 drawdown, risking $500 a trade means four losses in a row ends it. Risking $200 means it takes ten.
2. Misunderstanding the trailing drawdown
A trailing drawdown moves up as your balance makes new highs. If you're up $1,500 and give $1,500 back, you haven't "broken even" as far as the rule is concerned. Your buffer has shrunk by $1,500. Depending on the firm it may trail your closed balance or your intraday equity, and that difference matters.
3. Revenge trading after a loss
One loss, then a rushed trade to win it back, then a bigger one. Most daily loss limit breaches come from the third and fourth trade of a bad day, not the first.
4. Trading through high-impact news
Spreads widen and price can jump straight through a stop during releases like CPI or the US jobs report. Some firms restrict trading around them. Even where they don't, one bad fill can cost a day's limit.
5. Treating each fee like a lottery ticket
Buying another challenge straight after failing feels like a fresh start. Without a change in process, it's the same result with a new fee.
How to fix it: build the plan around the rules
- Start from the drawdown. Decide how many consecutive losses you must survive. Ten is a sensible number. Divide your drawdown by that to get your maximum risk per trade.
- Set a personal daily stop inside the firm's limit. If the firm's daily limit is $1,000, stop yourself at something like half of it.
- Cap trades per day. Two or three high-quality setups beats eight rushed ones.
- Protect open profit. On a trailing drawdown, decide in advance when you'll lock in profit or step away.
- Plan the calendar. Know every high-impact release in the week and decide in advance whether you're flat or trading it.
- Journal every trade. Mark whether it followed the plan. Most failed challenges have a clear pattern in the journal.

Quick answers
What is a trailing drawdown?
A trailing drawdown is a loss limit that moves up as your account makes new highs. If your balance rises, the floor rises with it, so profit you give back reduces your buffer. Firms differ on whether it trails your closed balance or your intraday equity.
Should I trade the news during a prop firm challenge?
Check your firm's rules first, as some restrict it. Even where it's allowed, spreads widen and slippage increases around high-impact releases, so many traders stay flat unless news trading is part of their tested plan.
How much should I risk per trade on a prop firm challenge?
Work backwards from the drawdown. If you want to survive ten losses in a row on a $2,000 drawdown, your maximum risk is $200 per trade. Many traders use less.
