Trading in the currency markets requires a trader to think in a slightly different way also about margin. Margin on the forex is not a down payment on a future purchase of equity but a deposit to the trader's account that will cover against any currency-trading losses in the future. A typical currency trading system will allow for a very high degree of leverage in its margin requirements, up to 100:1. The system will automatically calculate the funds necessary for current positions and will check for margin availability before executing any trade.
