Quote from cvds16:

guys this must be the winner for the most stupid thread I have come across at ET. There is totally no point in trying to be long and short at the same time unless you are doing calender spreads and then you'd better know what you are trying to achieve.
One long and one short equals nothing ! If you want to trade two strategies just calculate your net position. All the rest (well mostly) written above here is BS.

In congruence with the above:

Futures are CONTRACTS that are cash settled every day. When u win money is added to your account. It is not like a security such as a stock where there is a "holding period" that means anything significant.

This mental confusion and your failure to know the SPY - ES ratio suggest that for best results you might study up before jumping in the ring.
