The 5 mistakes that sink a prop firm challenge
Five concrete mistakes that get traders disqualified during a challenge — and how to avoid them from day one.

Most challenges are lost on the same mistakes. Here they are, ordered by frequency.
1. Risking too much per trade
Wanting to hit the target quickly pushes traders to oversize. This is mistake number one. Cut your risk: a challenge is won by surviving, not sprinting. See our risk management rules.
2. Ignoring the maximum daily loss
Many traders don't even know their exact daily limit. Write it down, then set yourself a stricter personal limit. Once you reach it, you close the platform.
3. Trading high-impact news
Entering a position just before a major macro release (NFP, a rate decision) is a coin flip with a widened spread and unpredictable slippage. Learn to anticipate them in how to read the economic calendar.
4. Overtrading to win it back
After a loss, the brain demands immediate revenge. That is the mechanism of revenge trading, and it is how a small loss becomes a disqualification.
5. Not tracking your trades
Without a journal, you cannot know whether you are following your plan. Objective tracking is the only protection against self-deception.
Altiora combines challenge tracking, a risk calculator and an automated journal to neutralise all five. Try it free for 7 days.
