No worries mate, yeah some rebate outfits will pay into your brokerage account the next day, but I try to work it out with the broker so it just comes right off your commission charge to begin with.
There are definitley a lot of shady ones out there and they are often big firms so it's very hard to navigate. Look at FXCM, they banged on about their No Dealing Desk (ECN) accounts and then it comes out they just set up a shell company to take the other side of their client's trades. That got them a whopping fine and banned from the US, though they are still operating around the globe and probably still up to the same old dirty tricks.
