We all know they are Market Makers, and they make their profit from the spread, oppose to the DMA, where brokers make their profit through the commission. Lets face it, the CFDs and the SB industry is growing rapidly and there is nothing you can do about it. So why do people lose trading SB, and why is it not particular bad in this regard compared to DMA? This simply because, they make the same mistake in not applying a basic trading discipline ,whatever market they trade. I also like to add, due to the fact that you do pay a price to get into the trade, the odds are against you whatever market you choose to trade.
