Margin Trading

Margin trading is a method of trading financial instruments — most commonly forex, indices, and commodities — by using borrowed capital from a broker. The trader deposits a portion of the full position value (the margin) as collateral, and the broker provides the remainder. This mechanism allows traders to control positions much larger than their deposit alone would support, amplifying both potential gains and losses.

Leverage and margin are closely related but distinct concepts. Leverage is expressed as a ratio (e.g., 100:1) and indicates how much of the position value a trader controls relative to their deposit. Margin is expressed as a percentage and represents the amount the trader must hold in their account to maintain the position. A 1% margin requirement corresponds to 100:1 leverage. If the account balance falls below the required margin level, the broker may issue a margin call and close positions automatically.

For forex affiliates and introducing brokers, margin trading is a fundamental concept because it underpins how trading volume is generated. The higher the leverage available, the larger the positions traders can open relative to their deposits — directly affecting lot-based commission earnings for IBs and the spread revenue of the broker. However, high leverage also increases client account risk, which can lead to faster client churn if traders are not appropriately educated.

Regulatory changes have significantly restricted leverage available to retail clients in major regulated markets. The European Securities and Markets Authority (ESMA) capped retail forex leverage at 30:1 in the EU. The FCA applied similar limits in the UK. These restrictions affect which markets affiliates can effectively promote and require careful consideration of client base when selecting which broker to partner with.
