my US GFT will take your 2nd entry and average it into the 1st entry. The result is a single position with the total size and average price of both entries.
I think it bypasses the FIFO rule because essentially both entries have been made homogenous and deciding which should be closed first is pointless because your whole position is averaged at one price.
If you're not used to it, you might find it annoying. But now that I've been using it for awhile, I think I'd prefer it over separate positions. By the way, I don't have to exit the whole position at one time, I can sell-off pieces of that position at various prices no problem. And if it's a huge problem, you can always just mark your entries with a horz. line
