Frequently Asked Questions
What is The5%ers's daily loss limit?
The5%ers's daily loss limit is 4% of your account balance. For the $20,000 account, the daily limit is $800.
What drawdown type does The5%ers use?
The5%ers uses static (floor never moves). The floor is fixed at account opening and never moves up, even when you profit.
What win rate do I need to pass The5%ers?
The minimum win rate depends on your reward-to-risk ratio. With a 1.5:1 R:R, a 45% win rate gives you a positive expectancy. With 1:1 R:R, you need above 55%. For The5%ers's 4% max drawdown, lower risk per trade (0.5-1%) dramatically reduces your risk of ruin even with modest win rates.
What is a good risk of ruin percentage for prop trading?
A risk of ruin below 5% is considered safe for prop firm trading. Below 1% is excellent. Most failed prop firm traders have risk of ruin above 30% because they risk too much per trade (2%+ of account) or have a negative expectancy strategy.
