The 3-5-7 rule: a strategic approach to trading

The 3-5-7 rule is a risk management method in trading that is based on three fundamental principles. It aims to optimize performance while limiting exposure to potential losses. Let's take a detailed look at this strategy and its application in the trading world.

Origins and Objectives of the 3-5-7 Rule

This approach, also known as the "Three Transaction Rule", is the result of the experience of seasoned traders. They designed this framework to meet the need for rigorous risk management in the dynamic world of financial markets.

The main objective of this rule is to establish a balance between the potential for gain and the protection of capital. It provides clear guidelines for allocating resources and making informed decisions, while maintaining controlled exposure to the inherent risks of trading.

Decoding the 3-5-7 Rule

Let's analyze each component of this rule to understand its functioning and its impact on the trading strategy.

The first figure: limiting risk per transaction

The "3" rule states that a trader should never risk more than 3% of their capital on a single trade. This restriction acts as a shield, preventing an unfortunate trade from having a devastating impact on the entire portfolio.

By respecting this limit, the trader adopts a rational rather than emotional approach. This forces them to carefully evaluate each opportunity, weighing the risks and potential benefits before committing their funds.

Illustration: With an account of €10,000, the maximum allowable loss on a single transaction would be €300.

The second figure: management of overall exposure

The "5" of the rule concerns the total exposure of the portfolio. It states that the aggregate of open positions should not exceed 5% of the total trading capital. This guideline encourages diversification and reduces vulnerability to a single market or asset.

This approach encourages traders to explore different asset classes or sectors, thereby fostering the development of a more balanced and resilient portfolio.

Example: For a portfolio of €50,000, the maximum exposure to a single market or asset class should not exceed €2,500.

The third figure: optimizing the gain/loss ratio

The "7" rule aims to ensure that winning transactions significantly offset losses. The goal is to achieve profits that are at least 7% higher than the losses on successful transactions.

By setting this target, traders are naturally encouraged to prioritize high-potential opportunities and to avoid less promising setups. This approach helps to improve long-term profitability by ensuring that the best trades generate gains that exceed the losses incurred on the less successful ones.

Example: A trader with an account of €100,000 should not have more than €7,000 exposed simultaneously in the market.

The effectiveness of this rule is optimal when the trader has sufficient flexibility to manage their risks without being hindered by additional costs.
