Judge a trade before you take it. Enter your entry, stop-loss and target to get the risk/reward ratio, the win rate you would need just to break even, and the expected value per trade.

Discipline is the hard part. A bot takes the same risk/reward on every entry and never moves the stop. Test it on paper, no real money at risk.

How risk/reward is calculated

  1. 01

    Measure your risk: the distance from entry to stop-loss.

  2. 02

    Measure your reward: the distance from entry to target.

  3. 03

    Divide reward by risk. A 1:2 means you stand to make twice what you risk, so you only need to win about a third of the time to break even.

R:R = |Target - Entry| / |Entry - Stop|

Worked examples

1:2 risk/reward

Entry $100, stop $95, target $110: the risk is $5, the reward is $10, so the ratio is 1:2. The breakeven win rate is about 33%.

Expectancy at a 50% win rate

At 1:2 and a 50% win rate, expectancy is 0.5 × 2 - 0.5 = +0.5R. Every trade is worth half your risk on average.

Frequently asked questions

What is a good risk/reward ratio?

There is no single answer. A higher ratio lets you be right less often and still profit, but targets that are too far may rarely get hit. What matters is that your ratio and your real win rate produce a positive expectancy.

What is the breakeven win rate?

It is the percentage of trades you must win just to break even at a given risk/reward. At 1:1 it is 50%, at 1:2 about 33%, at 1:3 about 25%.

What is expectancy?

Expectancy is the average result per trade, measured in units of risk (R). Positive expectancy means the strategy makes money over many trades; negative means it loses, no matter how it feels.
