Margin is a good faith deposit or collateral you maintain in your trading account to keep positions open. Expressed as a percentage of the position size, it determines how much capital you need to control a larger position. A 1% margin requirement means depositing 1% of the total trade value.
How Margin Works
Margin allows you to access leverage—borrowed funds from your broker—to control positions larger than your account balance permits. This amplifies both potential profits from favorable price movements and potential losses from adverse ones.
Key Concepts
Margin Requirement
Set by brokers, this is the minimum capital needed to initiate and maintain a trade, expressed as a percentage of position size.
Margin Call
Issued when your account balance falls below the required margin due to losses, demanding you deposit additional funds or close positions.
Leverage Ratio
Determines the amount of borrowed funds relative to your capital. Higher leverage amplifies both profits and losses.
Risks of Margin Trading
While margin increases profit potential, it introduces substantial risks. Failure to maintain adequate margin leads to forced liquidation of positions, often at unfavorable prices. Emotional stress from high leverage can impair decision-making.
Successful margin trading requires disciplined risk management, including stop-loss orders and careful position sizing to protect your capital.
