Margin is the amount of money you have to put upfront for the forex broker to give you leverage. Say you want to open a trade position of $200,000 at a leverage of 1:100, your broker will allocate $2,000 from your account as your equity for the position.
The $2,000 deposit is "margin".
Most brokers have minimum margin requirements. Major broker requirements hover around 2% (or 50:1) on the major currency pair and 5% (20:1) or more for the minor currency pairs.
Margin is usually expressed as a percentage of the full amount of the position. For example, most forex brokers say they require 2%, 1%, .5% or .25% margin. In the table below you can see the leverage levels associated for different margin requirements.
