Do the volume and price of stocks traded in black pools show up in the volume and price of stocks on an intraday (or even historical) basis (for instance on cnbc.com or my trading platform)?
From all I could gather, it sounds like black pools are required to print this information on the consolidated tape (recorded as over the counter) within 90 seconds of a trade being made. I do understand that black pools do not show what happens before and during a trade, but they must show what happened after the trade (even if it is slightly delayed), correct? By the way, is the data from the consolidated tape then reflected in the volume and price of a stock?
I became confused because I read that Credit Suisse has stopped giving their data to Tabb group and Rosenblatt Securities. (See for instance, http://www.businessweek.com/articles/2013-04-22/credit-suisse-making-dark-pools-even-darker ). The articles make it sound like CS is hiding a bunch of information. But aren't they required to give this information on the consolidated tape anyway?
Thank you.
