It's very possible to long term on futures especially if you have a large margin so you won't be liquidated if you are on a cross trading. But I prefer short term trading on futures because I am always using isolated on trading in futures because of the small margin I have. A small margin can be liquidated on a cross trading easily. Well, I always believe that we should find our own way on how we trade, We do have different situations in life and the compatibility of trade style depends on us.
