Question 1

What is a good risk-reward ratio?

Accepted Answer

Many traders want at least 2:1 — risking one to make two. That way you can be wrong more than half the time and still profit. Below 1:1 you need a very high win rate just to break even, which is hard to sustain.

Question 2

How does it set my required win rate?

Accepted Answer

Break-even win rate = 1 ÷ (1 + reward-to-risk). At 2:1 you need to win only about 33% of the time; at 1:1 you need over 50%. A better ratio lowers the bar your accuracy has to clear.
