Margin Trading

The forex market is a 100% margin-based market. This is a familiar thing for those used to trading futures.

In fact, spot forex trading is essentially trading a 2-day forward (futures) contract. You do not take actual possession of any currency, but rather have a theoretical agreement to do so in the future. That puts you in a position of benefiting from prices changes. For that your broker requires a deposit on your trades to provide surety against any losses you may incur. How much of a deposit can vary. Some brokers will asked for as little as 1/2%. That is fairly aggressive, though. Expect 1%-2% on the value of the position in most cases.

Now, unlike the stock market, margin trading does not mean margin loans. Your broker will not be lending you money to buy securities (at least not the way a stock broker does). As such, there is no margin interest charged. In fact, since you are the one putting money on deposit with your broker, you may earn interest in your margin funds.
