ACM is one of the largest brokers in the FOREX market. They offer 4 user friendly platforms which can be accessed via web and via mobile phones. While it is easy and convenient to trade with ACM, the minimum deposits required are extremely high, starting at $2,000 for mini accounts! The minimum lot size is 100,000 units, and spreads are not fixed, thus exposing the trader on ACM to high risks during volatile markets.
