January 9, 2018 my bid at .01(my brokerage doesn’t trade subpenny and I was lucky enough to get a bid in while trading tapped .01 that day) got filled at .0082. I got screwed because I can’t buy subpenny, I would have preferred to have had the full value at .01 since that’s as low as I can get.

I think that could be what The Herb means when his buy got filled at .0018, notice how he focuses on total shares. Same happened to me, I got same total shares, my disappointment is that my trading fee to value of trade was higher than desired. That’s the equivolent to a $10 bid trade getting filled at $8.20 except I can’t keep buying dips. Not sure if this kind of MM decision making favors MYDX. Seems to favor beneficiaries of declining shareprice.
