This structure is not a market maker. Market makers are manipulating the market to make you loose. Structures like this are simply trading against you. It is not exactly that your profit is their loss but your losses always increase their profit. As you can see, when they make a mistake and you manage to earn profit, they still have a way to escape without paying it. That is what their "Terms & Conditions" are rigged for. It is very important to have them here on FPA Traders Court. However, if such structure faces too much pressure it simply vanishes to pop up later somewhere else under different name.
