Correct me if I am wrong...Perhaps, I do not understand something...But what is wrong with trading in cash indices? You are telling me that a cash index follows the futures, but how that can be? I thought that Dow and S&P did not follow anything and that they float on their own...Can anyone please explain? And also, why people who offer such kind of trading will necessarily take me to the cleaners? The issue is rather sensitive for me, because I have been studying index behaviour for quite a while, which is why I want to trade in cash indices, not ETFs
