Understand the race
A typical $50,000 evaluation might ask for $3,000 profit with a $2,000 trailing drawdown. The finish line is $3,000 away; the cliff is $2,000 away, and on a trailing account the cliff follows you up as you make money. You are not trading a $50,000 account. You are trading a $2,000 one.
Size against the drawdown
Decide how many consecutive losses you want to survive — many funded traders use 6–10. Divide the drawdown by that number: $2,000 ÷ 8 = $250 per trade. That is your maximum risk, not your target. Then use the position size calculator to turn it into contracts — often micros.
The prop firm challenge calculator shows how your odds change as you move that number: smaller size, slower pass, far fewer blown attempts.
Respect the daily loss limit
If your firm has a daily loss limit, set your own personal limit below it — for example half. The worst evaluation days are a loss followed by forced trades to win it back.
Know the trailing floor at all times
An end-of-day trailing drawdown moves only at the close; an intraday one can move on an open profit you never banked. Read trailing drawdown explained before your first day, and keep the floor written somewhere you’ll see it.
Read the consistency rules
Some firms limit how much of your profit can come from one day. A single big day can make you wait or trade more. Copy the exact rules from your firm’s current rules page — they change.
A simple process
- Fixed risk per trade sized for 8 losses.
- Personal daily stop at half the firm’s limit.
- Max trades per day decided before the open.
- Journal every trade, review every weekend.
LoggingTrades tracks trailing or static drawdown, the daily limit, profit target and consistency rule for each account, with warnings at 50, 75 and 90% of every limit — with presets for common firms. Always check the numbers with your firm.
FAQ
What risk per trade should I use in a prop firm challenge?
A common approach is to size so 6–10 consecutive losses fit inside the drawdown — for a $2,000 drawdown that is roughly $200–$330 per trade.
Is it better to pass fast or slow?
Slower, smaller sizing usually raises your probability of passing; aggressive sizing passes some attempts quickly but fails many more.
