Risk-Reward Ratio
The distance from entry to target divided by the distance from entry to stop. A ratio of two means the target is twice as far away as the stop.
The ratio is a property of the plan, fixed the moment the levels are set, and it determines what hit rate is needed to break even: a two-to-one plan needs to work slightly more than a third of the time. That is why a success rate published without its risk-reward ratio is unreadable — 70% sounds impressive until you learn the target sat a fifth as far away as the stop, at which point a coin toss would have done better. Every rate on this site is published beside the baseline that ratio implies.
