I received the same message, just ignore it.
You need to figure out how much of AVD is traded in dark pools. Some stocks are mostly traded on exchanges. I use DarkSeek (DS). Choose aggressive with minimum fill size of 200. I usually ignore WoW but if you really want to get faster fills, just select Seek Aggressive with inside NBBO or midpoint parameter. Dark pools are for privacy and price improvements not for faster fills. Sorry, I don't use Blitz. If I'm in a hurry, I use two algos at the same time, IB's VWAP and Jeff algo's Darkseek.
