I looked on the general topics but didn't see anything about this. A mod can feel free to close/move this as they see fit.
Anyway, I just had the following happen, a stock was trading with a bid of .015 and ask of .016. I put a sell in for .0159, and it never showed up on L2. After a looong while, I saw that my sale had gone through. Saw 150,000 at .0159 and at the exact same time 150,000 at .0160. Is this a case where I "sold" mine at .0159 and the other person "bought" theirs at .016 and the MM kept the difference?
Is that how mirror trades work? And if so, is it legal?
Not too worried about it, just curious, really.
