Risk-Reward Ratio Calculator
Enter your entry, your stop, and your target. Returns the risk-reward ratio and - the part that makes it actionable - the win rate that ratio requires to break even. At 3:1 you can be wrong three times out of four and still come out level; at 1:1 you need better than a coin flip. Works for shorts by putting the target below the entry. Not the same as the R-multiple calculator: this one plans a trade from a target, that one reviews a trade from its exit.
