Let's say that I go long 1 ES contract. Then I decide I want to be short. Do I just sell 2 contracts, or do I have to sell 1 to close and then sell 1 more to open the short position?
Either one! Odds are you lost money on the long, so you'll probably lose more on the short. Stay on the simulated account for a year, then you have a shot.
Just sell 2 to reverse from 1 long. With futures, there is no distinction between a sale that closes a long or one that opens a short. It is simple "first in, first out" (FIFO) accounting.
I have no tolerance for lazy MFer's in this bidness, especially with GOOGLE and this site..... newbie schmoobie, I do not care, I got beaten up many times on the NYSE floor and upstairs for dumb stuff and being lazy.
