Do SB firms make it impossible to win big? I've read so many messages on the internet from people saying it is impossible to win big with spread betting. If you are succesful and trade with a big stake, the sb firms boycot you from winning. IS THIS TRUE? Are the SB firms some sort of maffia where you can only loose money? Can they do that? Isn't there some kind of law or regulations to protect the clients from the sb firms???
