This is a good test for Go Markets.
It is obviously a liquidity problem that they need to sort out.
They apparantly make their money from spreads alone so to them it should not matter.
It is just a matter of getting the orders filled at the quoted prices I suspect
A market making broker makes money from the spread AND trading with/against you. They are creating the market you trade on (as opposed to an ECN platform which aggregates prices from many market makers (banks)) so they have a lot of control over what you do. The difference between the two models: ECNs want you to do higher volume so they get more commission, Market Makers want you to do lower volume and set stops/take profits so they know what you're aiming to do so they can hedge by trading the same way or completely against you (you buy, they sell (and do something to your feed in the meantime))...
