No-deposit bonuses give you a small amount to trade with before you fund the account. They are the lowest-risk way to test a broker, but the amount is modest and withdrawal usually requires meeting a turnover target first.

XM
XM gives new clients a $30 trading credit with no deposit required, claimable after SMS phone verification in the Members Area.
RoboForex
