Risk/Reward Ratio

The risk/reward ratio is an analytical tool used to assess the viability of a trade before execution by comparing the distance between the entry point and the stop-loss (risk) to the distance between the entry point and the take-profit target (reward). It is typically expressed in formats such as 1:2 or 1:3, meaning the trader risks one unit in expectation of making two or three units in profit.

This ratio is calculated using the following formula: Risk/Reward Ratio = (Entry Price - Stop-Loss) ÷ (Profit Target - Entry Price)

The importance of this ratio lies in allowing a trader to achieve profitability even with a win rate below 50%. For instance, when using a 1:3 ratio, a trader can lose 3 out of 4 trades and still break even or make a slight profit. Therefore, it is considered one of the most essential risk management tools, which must be paired with the win rate to determine a strategy's mathematical expectancy.

Common mistakes include frequently using an unfavorable risk/reward ratio such as 2:1 or 3:1 (where risk exceeds reward) without a high enough win rate to offset it, or moving the stop-loss after entering a trade, which disrupts the pre-calculated ratio and exposes capital to greater risk than originally planned.
