It seems over the last few years of reading and learning about the markets and those who "claim" to be successful, many seem to either have been trading futures from the beginning or have shifted to futures later. I know the obvious advantage of being able to go short as easily as long may be one reason. Also, the leverage is greater, but of course that is a double-edged sword. Is there any other reason that great traders seem to be trading futures rather than equities. Or maybe my assumption is wrong from the beginning?
