just a reminder this for profit site (2012) became the *largest* entity specific to OTC ATS Dark Pool %s with that *data* first (transparency) shown back in 2014 .. *oddly* they seemingly fell off the *reported* % stats (at least for specific massively targeted OTC stox tracked) .. just about a year ago .. leaving for those targeted OTC stox .. just one *entity* reporting .. ECN (ARCA)
like a few other aspects imo *not visible* .. clean up in aisle NN has been *underway* for a few years ..
