Leverage the risk-reward ratio: Profit maximization calculation methods and implementation strategies

To achieve stable results in trading, it is important to understand not just “wins and losses,” but also how much can be earned and how much can potentially be lost in a single trade beforehand. Here, the concept of risk-reward ratio comes into play. By understanding and correctly utilizing this indicator, long-term profitability can be greatly improved.

What is the Risk-Reward Ratio

The risk-reward ratio is a numerical representation of the relationship between the “maximum loss amount” and the “expected return amount” in a single trade. In other words, it serves as a tool to determine whether the profit opportunity is commensurate with the risk taken.

Considering a simple example, a trade that risks 100 yen to aim for a profit of 200 yen can be said to have a good risk-reward ratio. Conversely, a trade that aims for a profit of 30 yen with a risk of 100 yen has a low expected value and should be avoided.

Importance of the 1:2 Ratio and Calculation Steps

The industry standard is to have a risk-reward ratio of at least 1:2. This means expecting at least 2 units of profit for every 1 unit of risk taken.

The specific calculation method is as follows:

1. Set entry price, stop loss, and take profit targets

   • Entry Price: 1,000 yen
   • Stop Loss: 900 yen
   • Take Profit: 1,200 yen

2. Calculate expected loss and expected return

   • Expected Loss = 1,000 yen - 900 yen = 100 yen
   • Expected Return = 1,200 yen - 1,000 yen = 200 yen

3. Calculate the risk-reward ratio

   • Risk-Reward Ratio = 200 yen ÷ 100 yen = 2.0
   • In this case, the ideal ratio of 1:2 has been achieved.

Through this calculation process, you will be able to determine whether the trade is statistically worthwhile.

Implementation Method to Incorporate into Trading Strategy

It is key to not let the risk-reward ratio remain a mere theory, but to incorporate it into actual trading decisions for success.

Verification process before starting a trade:

First, for potential trades, calculate the risk-reward ratio by working backward from the set entry price, stop loss, and take profit. Then, confirm that this value is 1:2 or higher. If it is below 1:2, it may be necessary to either skip the trade altogether or adjust the position of the stop loss to improve the ratio.

Management across the entire portfolio:

It is important to be aware of the average risk-return ratio not just for a single trade, but also when combining multiple trades. By accumulating profits from trades with a high risk-reward ratio, it is possible to increase profits over the long term even with a slightly lower win rate.

By thoroughly eliminating low-quality trades (with a risk-reward ratio of 1:1 or lower) and concentrating management resources on trade opportunities with favorable risk-return structures, you can achieve an improvement in trading performance.
