It's supposed to be first in first out, but there really isn't a way to know, because of all the strange ways shares can be sold and the fact that each morning different MMs queue up all over again (so your position won't necessarily be the same each day even if it's the same GTC sell orders from the previous day).

Just keep your order in for whatever the good til cancelled are for your broker.

whatever group is pumping this won't get it far, but if it's anything like last time they may chew the .0001s and give an opportunity to get out, who knows. GLTY
