Common Mistakes That Cause Prop Firm Challenge Failures
Ten common mistakes that end prop firm challenges, from oversizing and revenge trading to floating losses, weekend gaps and prohibited strategies, and how to avoid each one.
Challenge accounts rarely fail because of one unlucky trade. They fail because of habits that repeat: too much size, too little patience or a rule that was never read properly.
The good news is that every mistake on this list can be avoided. For each one, we explain why it happens, what it looks like in numbers and what to do instead.
1. Not reading the rules properly
Rules look similar from firm to firm, but the details differ, and the details are what end accounts. Typical surprises include:
- discovering that floating losses count towards the daily limit;
- not knowing when the trading day resets;
- reaching the target with a position still open and expecting the phase to pass;
- assuming a trailing maximum loss behaves like a static one.
Instead: read the full rules once before you start, and write the key numbers down in dollars. At Fundzoria, targets count closed profit, every position must be closed to pass, the day resets at 00:00 Europe/Athens and limits are checked against equity. The trading rules page explains each one with a worked example.
2. Oversizing to reach the target faster
The pressure of a target makes larger positions feel reasonable. They are not. A position that is too large turns an ordinary price move into a breach.
- On a $100,000 2-Step account, the daily allowance is $5,000.
- A 20-lot position on EUR/USD gains or loses $200 per pip.
- The whole daily allowance is gone after a move of about 25 pips against you, which is an ordinary intraday move for that pair.
At Fundzoria, risking most of the loss allowance on one one-sided idea is treated as all-in gambling: a warning and excluded trades the first time, and a hard breach if it is repeated.
Instead: keep a small, fixed risk per trade and accept that the target takes as long as it takes. Fundzoria has no time limit, so there is nothing to gain by rushing.
3. Revenge trading after a loss
A loss stings, and the urge to win it back straight away is strong. Revenge trades tend to be larger, faster and outside the plan, which is why they so often turn one loss into several.
Instead: after a loss, step away from the screen for a few minutes. Set a rule such as “two losses in a row and I stop for the day”, and follow it even when the next setup looks perfect.
4. Ignoring floating losses and the daily reset
Some traders watch only their balance and forget that open positions affect equity. At Fundzoria, equity is what matters: a floating loss counts towards the daily limit the moment it appears.
The reset adds a second trap. Because the new day starts from your balance, a position held past 00:00 Europe/Athens with a floating loss begins the new day already part of the way to the limit.
Instead: check equity, not balance, before every new trade, and avoid carrying large floating losses into the reset. Our guide to daily drawdown and maximum loss walks through both cases with numbers.
5. Trading without a stop loss
Trading without a stop loss feels flexible until the market moves quickly. Then the decision to close is made under stress, and usually too late.
Instead: place a stop loss on every position, where the idea is proven wrong, and size the trade to it. At Fundzoria a stop loss is optional but strongly recommended, because limits are checked as prices move.
6. Overtrading
More trades do not mean more progress. Every trade carries costs, and every extra trade is another chance to break your plan.
- Round trips per day
- 30
- Size per trade
- 2.00 lots
- Commission per lot, per side
- $3.50
- Commission per day
- $420
- Commission over 10 trading days
- $4,200
Spreads come on top. Placing more than 200 orders in one trading day also falls under Fundzoria’s hyperactivity rule.
Instead: set a maximum number of trades per day in your plan and only take setups that meet every condition.
7. Holding oversized positions through high-impact news
Interest-rate decisions, inflation figures and employment reports can move forex and gold far beyond their usual range within minutes. Stops can fill at worse prices when the market jumps.
On Fundzoria evaluation accounts, trading around news is allowed. On Real accounts, new orders are blocked from 2 minutes before to 2 minutes after a high-impact release affecting the instrument, although existing positions can be held and closed.
Instead: check the economic calendar every day, and reduce or close positions before releases you do not want to be exposed to.
8. Forgetting about weekend gaps
Forex and metals close on Friday and reopen on Sunday at 22:00 UTC. Prices can open well away from Friday’s close, and stop loss, take profit and pending orders are then filled at the first available price, which can be worse than the level you set.
Instead: decide before Friday whether a position is worth holding over the weekend, and size it for a gap rather than just for its stop loss. Crypto trades 24/7, so weekend moves there happen in real time.
9. Using a prohibited strategy
A profitable account can still fail if the trading breaks a conduct rule. At Fundzoria, the following are not allowed:
- automated trading, scripts, macros and browser automation;
- copy trading between people, signal-copying services and pass-my-challenge services;
- cross-account hedging, meaning opposite positions on different accounts;
- arbitrage, latency trading and exploiting platform errors or mispriced quotes;
- account sharing, third-party management and multiple profiles.
Some of these are soft breaches the first time, with a warning and excluded trades. Others, such as copy trading and cross-account hedging, are hard breaches that end every account involved. On Lite, profit from trades closed within 30 seconds is also limited in the evaluation phases.
Instead: trade your own ideas manually, on your own accounts, and read the prohibited strategies section of the rules before you start.
10. Changing the plan in the middle of the challenge
After a few losses it is tempting to switch strategy, timeframe or market. Each switch throws away what you have learned about your edge and usually adds risk, because the new approach has not been tested.
Instead: decide before the challenge which strategy you will trade and how you will judge it. Review any changes at the weekend, not in the middle of a session.
A bonus mistake: letting the account go inactive
Fundzoria has no time limit, but every account must place an order or close a position at least once every 60 days. An open position on its own does not count as activity, and missing the deadline is a hard breach. If you plan a break, set a reminder.
A quick self-check before every session
- Do I know today’s daily loss level and my distance to the maximum loss floor, in dollars?
- Is my risk per trade fixed and written down?
- Have I checked today’s high-impact news?
- What are my personal daily stop and my maximum number of trades?
- Is there anything in my plan I feel tempted to break today, and why?

Key takeaways
- Read the rules in full and convert them into dollar amounts.
- Oversizing and revenge trading turn ordinary losses into breaches.
- Floating losses count, and positions held past the reset carry their losses into the new day.
- Use a stop loss on every trade and plan for news and weekend gaps.
- Avoid prohibited strategies and keep the account active at least once every 60 days.
Frequently asked questions
What is the most common reason challenges fail?
We do not publish failure statistics, and figures quoted online are hard to verify. What the mistakes in this guide have in common is a loss that grew too large for the limits, through oversized positions, revenge trades or positions without a stop loss.
Can I try again after failing a challenge?
Yes. A breached account cannot be reactivated, but you can start again with a new account at any time.
Is it a mistake to trade gold in a challenge?
Not in itself, but gold moves in large steps. At Fundzoria, a $1.00 move on 1.00 lot of XAU/USD is worth $100, so sizing has to account for that. Our gold risk management guide shows how.
Does a soft breach end my account?
No. A soft breach keeps the account open, but affected trades or profit are excluded, or progression is held, and a warning is recorded. Repeated soft breaches can be treated as a hard breach.
Do I have to trade every day?
No. You need at least 3 trading days per phase and some activity at least once every 60 days, but there is no requirement to trade daily.
