Why trade on margin?
Trading on Margin (Trading with Leverage*) is a common attraction of the forex market. It allows you to open trades that are larger than the capital in your account. Trading on margin can both positively and negatively affect your trading experience as both profits and losses can be dramatically amplified.
* Leverage is a double-edged sword and can dramatically amplify your profits. It can also just as dramatically amplify your losses. Trading foreign exchange with any level of leverage may not be suitable for all investors.
