Just noticed more on that 10k trade b4 or after a sub penny trade. Got a partial fill on 340k at .0001 on TCEL. 1st 10k went at .00015 and the next 330k at .0001. Guess the mm needs to eat the difference, a few pennies, by providing me the 10k at .0001 while paying .00015 for them. The Games continue.
