Understanding Risk/Reward for Prop Firms
Why R:R Matters in Challenges
Prop firm challenges require you to hit a profit target while staying within drawdown limits. A higher R:R means you need fewer winning trades to reach your target — which also means fewer trades that could trigger loss limits.
A trader with a 1:2 R:R only needs a 33% win rate to be profitable. Compare that to a 1:1 trader who needs 50%. Fewer required wins = less exposure to drawdown events.
