Thatsmagic, Oanda is a market maker and probably more so a "Bucket Shop" they have been around a while and from what i can recall in the past, profits were always payed out to traders but if your to profitable, then they will ask you to leave and close your account down just like most brokers these days.
They have a decent net capital amount well above the required amount.But i don't have any experience with this broker so i can only go on past reviews by the various traders.
Some other relevent info for you below.....
