Just open live account with some small fund to test it. I truly think you will figure it out by yourself and FPA could be a great source of references for checking any broker.
Some brokers as HotForex requires you to trade the number of lot = 2/3 bonus amount, assume you deposit $100 and get $100 bonus (100%), you have to trade at least 75 lot to acquire the bonus amount.
wish this broker could improve the transactions history with latest show first, I made many transactions and have to switch pages every time I check my transactions.
