Risk/reward calculator
Ratio of a trade plan and the win rate you need to break even with it.
Example inputs, not market prices: change them to your trade.
Result
How it is computed
Ratio = |Target − Entry| ÷ |Entry − Stop| · Break-even win rate = 1 ÷ (1 + Ratio)
The ratio compares what the trade can make with what it can lose. The break-even win rate is the share of winners at which this plan neither wins nor loses over time.

Is a higher ratio always better?
Not on its own: a far target is reached less often. The break-even win rate tells you what hit rate the ratio needs.
What does expectancy in R mean?
The average result per trade in units of risk. With your win rate entered, +0.25R means you make a quarter of your risk per trade on average.
Does it work for short trades?
Yes: choose Sell; the stop must then be above the entry and the target below.
