Why Traders Fail Prop Firm Challenges
Challenges usually end on a rule breach rather than a missed target, and the common cause is position size too large for the room the rules allow.
At firms with no time limit, a challenge can only fail through a rule breach, so the real question is which rules traders break and why. The usual culprits are a daily loss limit hit on one bad day, a trailing drawdown that rose faster than expected, and conduct rules broken without realising it. Behind nearly all of them sits one habit: trading a position size that is too large for the room the rules allow.
How often challenges fail
Few firms publish figures, but those that do point the same way. Hola Prime publishes a customer pass rate of 35% for the period from 10 November 2024 to 29 May 2025, counting customers who traded at least one evaluation and obtained a simulated funded account. Topstep states that over 63% of traders have lost an account in a single day. The second figure matters most, because it shows how quickly one session can undo weeks of progress.
The breaches that end accounts
The daily loss limit
The daily limit can end an account within a single session, and the way it is measured catches traders out. Some firms set the day’s floor from the higher of balance or equity at the daily reset. Blue Guardian, for example, subtracts a fixed percentage of the initial balance from the higher of balance or equity at its 5 pm EST reset.
Take a made up $100,000 account with a 5% daily limit measured this way. At the reset the balance is $102,000 and an open trade shows $1,500 of profit, so equity is $103,500 and the day’s floor is $98,500. If that trade then drifts back and closes flat, the balance is $102,000 and the trader has only $3,500 of room left for the day, not the $5,000 they might expect. Holding open profit through the reset quietly tightened the limit.
Daily loss limit vs maximum drawdown explains how the two limits interact.
Trailing drawdown
A trailing limit follows the account up, and an intraday trailing limit follows open profit as well. On a made up $50,000 futures account with a $2,000 intraday trailing drawdown, the floor starts at $48,000. If a trade reaches $1,200 of open profit, the floor rises to $49,200. If the trade then reverses and closes $200 in profit, the balance is $50,200 and the remaining room is $1,000 rather than $2,200. A few trades like that can shrink the room to almost nothing without a single large loss. Trailing vs static drawdown works through more examples.
Consistency rules
A consistency rule can stop a trader passing even after the target is reached. DayTraders.com does not allow any single day in its evaluation to exceed 50% of total simulated profit. On a made up account with a $3,000 target, a trader whose best day made $2,000 would need $4,000 of total profit before passing, and every extra day of trading carries more risk of a breach.
Conduct rules
These end accounts that were otherwise on track, and they differ widely between firms.
- Holding times. Lucid Trading flags microscalping when more than 50% of profit comes from trades held five seconds or less. GOAT Funded Futures removes profit from trades closed within two minutes on several of its plans.
- Closing times. YLOS Trading requires all positions to be closed at least 30 minutes before the market close, and holding past the close blocks the account.
- News. YLOS funded accounts must be flat at the time of a news release, and Lucid treats trading red folder news as a hard breach on its LucidDaily plan.
- Risk per trade. Hola Prime Futures makes a stop loss mandatory on every trade and caps risk per trade idea at 2% of the initial balance on Tradovate, NinjaTrader and WealthCharts, and exceeding it terminates the account.
- Inactivity. GOAT Funded Futures requires a trade at least every 7 days, and The5ers Futures every 14 calendar days.

A worked example of position size
Many of these breaches trace back to size. Take a made up $50,000 account with a $2,000 maximum drawdown and a $1,000 daily loss limit, traded by someone whose strategy wins 45% of the time and makes twice the risk on each win.
| Risk per trade | Losses to hit the daily limit | Losses to hit the maximum drawdown |
|---|---|---|
| $500 | 2 | 4 |
| $250 | 4 | 8 |
| $200 | 5 | 10 |
Losing streaks are normal, not bad luck. Over 30 trades, a strategy that wins 45% of the time has roughly a three in four chance of at least one run of four losses in a row, and about an even chance of a run of five. At $500 per trade, a run of four losses ends the account. At $200 per trade, the same run costs $800, stays inside the daily limit and leaves $1,200 of drawdown in hand. The smaller size feels slow, but at a two to one payoff each win still makes $400, so eight wins and one loss, or ten wins and five losses, reach the $3,000 target without needing a lucky day.
The habits behind the breaches
- Chasing the target. Sizing up to finish quickly turns an ordinary losing run into a breach. There is rarely a deadline at firms with no time limit.
- Revenge trading. Taking extra trades to win back a loss the same day is how daily limits get hit. What counts as overtrading covers the warning signs.
- Trading through news without a plan. Volatile releases widen spreads and slippage, and some firms ban trading around them outright.
- Changing strategy mid challenge. Switching instruments or timeframes after a loss removes the one thing that was tested.
How firms differ
The same trade can be safe at one firm and a breach at another. Funded Futures Family has no daily loss limit on its evaluations and simulated funded accounts, while The5ers Futures applies a 2.5% daily limit on its 100K and 150K accounts that permanently ends the account if reached. GOAT Funded Futures treats its daily limits as soft breaches that close positions and pause trading until the next day. DayTraders.com lets traders choose intraday trailing, end of day trailing or static drawdown at purchase, and among its evaluations only the end of day plans carry a daily loss limit. Reading which version applies is part of the preparation.
Common mistakes
- Trading the maximum contract limit because it is allowed.
- Holding open profit through the daily reset on an equity based daily limit.
- Assuming a trailing drawdown only moves on closed trades.
- Skipping the prohibited strategies and holding time rules.
- Buying a reset and trading the new account the same day, at the same size, in the same mood.
Checklist
- Write down the daily limit, maximum loss and how each is measured before the first trade.
- Set risk per trade so that at least five losses fit inside the daily limit.
- Know the daily reset time and the forced close time.
- Check the consistency rule and plan to spread profit across days.
- List the conduct rules that touch your style: news, holding time, automation and copying.
- Stop for the day after a set number of losses, whatever the limit allows.

Frequently Asked Questions
Why do so many traders fail prop firm challenges?
A frequent cause is position size that is too large for the loss limits. With a tight daily limit and a small maximum drawdown, a normal run of four or five losing trades can end the account if each trade risks too much. Topstep states that over 63% of traders have lost an account in a single day, which suggests that single sessions, not slow declines, end many accounts.
Can I fail a prop firm challenge without losing money?
Yes. Conduct rules can end an account that is in profit. Examples include holding past a firm's forced close time, trading during a restricted news window, breaking a minimum holding time rule, exceeding a risk per trade cap or going inactive for longer than allowed. At YLOS Trading, for example, holding a position past the close blocks the account.
Why did my trailing drawdown move when I did not close a trade?
An intraday trailing drawdown follows the highest balance including open profit. If a trade reaches $1,000 of open profit, the floor can rise by $1,000 even though the trade is still open. If the trade then reverses, the higher floor stays. End of day trailing limits avoid this by updating only on the closing balance after the session ends.
How much should I risk per trade on a prop firm challenge?
There is no single answer, but a common approach is to size trades so that at least five losses in a row fit inside the daily loss limit and ten or more fit inside the maximum drawdown. On a $50,000 account with a $1,000 daily limit, that points to around $200 of risk per trade. Some firms also set their own cap, such as 2% per trade idea.
Is it better to pass a challenge quickly?
Rarely, if speed means larger positions. Many firms now have no time limit, so rushing adds risk without a matching reward, and consistency rules at many firms stop a single big day from passing the account anyway. A steady pace also builds the habits needed on the funded account, where the same loss limits apply and a breach costs more.
