DislikedAbout FIFO... Unless something has changed in the past couple of months, the way it worked for me is First In/First Out for the same sized position. For example, if you have 2 orders at 1000 units each, then the oldest one would have to be closed 1st. However, if you had one order at 1000 units, and a second at 1001 units, you could close either at any time. Again, this is just how it has worked for me, and I haven't even used this method of trading for a couple of months, so if anything changed since then, I am unaware of it. My suggestion to anyone...Ignored
