Low margin deposits or trade collateral are normally required in Foreign Exchange, (just as with regulated commodity futures). These margin policies permit a high degree of leverage. Accordingly, a relatively small price movement in a contract may result in immediate and substantial losses in excess of the amount invested. For example, if at the time of purchase, 10% of the price of a contract were deposited as margin, a 10% decrease in the price of the contract would, if the contract were then closed out, result in a total loss of the margin deposit before any deduction for brokerage commissions. A decrease of more than 10% would result in a total loss of the margin deposit. Some traders may decide to commit up to 100% of their account assets for margin or collateral for Foreign Exchange trading. Traders should be aware that the aggressive use of leverage will increase losses during periods of unfavorable performance.
