Risk Per Trade

What is Risk Per Trade?

Risk per trade is the maximum amount of capital you're willing to lose on a single trade, expressed as a percentage of your account balance. It's the starting point for your position sizing calculation and the single most controllable variable in your trading.

Most professional traders risk between 0.5% and 2% per trade. At 1% risk on a $100,000 account, a losing trade costs $1,000 — painful but survivable. At 5% risk, a losing trade costs $5,000, and three consecutive losses put you in serious drawdown territory.

Finding Your Risk Level

• Conservative (0.5%): Best for new prop firm challenges — allows 10 consecutive losses before hitting a 5% daily limit
• Moderate (1%): The most common choice — allows 5 consecutive losses before hitting daily limits
• Aggressive (2%): Requires high win rate — only 2-3 consecutive losses before daily limit concerns

The Math Behind Risk Per Trade

If your daily drawdown limit is 5% and you risk 1% per trade, you can lose 5 trades in a row before being forced to stop. With a 50% win rate, the probability of 5 consecutive losses is about 3% — unlikely but possible. At 2% risk, only 2.5 consecutive losses trigger the daily limit — a far more probable event. Choose your risk level by working backward from your drawdown limits.
