Forex trading – like any form of trading – is not without risk. Some may even suggest that trading in the forex market actually carries above-average risk. The one rule you must hold above all else is to trade only using your risk capital. In other words, never trade more than you can afford to lose.

Great inroads have been made to clear out unscrupulous brokers, but you must still exercise caution when selecting a new broker.
