Margin and leverage are among the most important concepts to understand when trading forex. These essential tools allow forex traders to control trading positions that are substantially greater in size than would be the case without the use of these tools. At the most fundamental level, margin is the amount of money in a trader's account that is required as a deposit in order to open and maintain a leveraged trading position.
In forex, investors use leverage to profit from the fluctuations in exchange rates between two different countries. The leverage that is achievable in the forex market is one of the highest that investors can obtain. Leverage is activated through a loan that is provided to an investor by the broker that is handling the investor’s or trader’s forex account.
