First of all, let's understand the actual margins. In forex currency sold in lots or in other words - $ 100,000. When trading with a margin account, the term "leverage" joins the game. Leverage shows money "borrowed" from brokers. Leverage varies from 1:50 to 1: 500, depending on the broker and the size of the trading position. For example, suppose you have opened a 1% margin account and deposited $ 1,000. 1: 100 leverage allows you to control $ 100,000, not just $ 1,000.
