So far as I know the percentage is about the same, not easier trading the real market. Not more than 5%-10% successful traders on both. It is a hard game that is for sure.Who can answer that? Ask proper questions. What you need to ask is how many Day traders and scalpers actually spread bet in comparison to DMA, and how many traders swing trade in comparison to DMA/Shares traders.
I will take a stab. I would guess there are considerably more successful DMA traders who day trade and infact make more money than spread bet day traders.
I know quite a few swing traders who buy shares and options over spread bets with their rolling day interest charges and real time draw down problems.
