Investopedia explains Mini Forex Account

Mini forex accounts are commonly used by beginner traders who are looking to gain experience in the forex markets. Traders are not limited to only trading one lot at a time, so these accounts are ideal for increasing exposure as trading confidence builds. To make an equivalent trade to one standard lot, a trader can just trade 10 mini lots. By using mini lots instead of standard lots, a trader is able to customize the trade and obtain greater control of his or her risk.
