Yes Oanda has the option that allows you to trade any amount you want as long as its above $1. You can also do leverage like that in FXCM if you want which I recommend. Leverage is essential in FX to make serious money, without leverage its not even worth our time.
my account with oanda is already less than $1 and they still allow me to trade. You can trade with oanda until you're completely wiped out. Wala silang patawad
