i paid for 2 l2's for over 16 months <alpha trade and equity feed> and i finally dumped alpha trade ~ due to their errors ~ at the end of feb ~ but imo they all have issues ~ like i said .. i keep ef .. because of their MMs' logs
btw ~ we just had a trade at 14:14:03 ~ 5,258 shares at the ask <.23>
bid ask is .22/.23 .. 1x2
pert lowered their bid to .18 <from .22> and hdsn is in between at .20 ~ info still the same on the ask ~
