Please correct me if I am wrong, but I have been under the impression the Anonymous and House are what one sees when a brokerage holds the shares in its account (street name) for its clients. So seeing a trade identified as either of these could be due to the action of any of the client accounts of that brokerage. The l2 on s#..house also uses an number to help one figure which trading desk a given anonymous in their l2 listing is.
so seeing anonyomous sell x amount of a stock and anonymous buy x amount of it, and the associated bid and ask and settle does not necessarily mean the one party was trying to move the pps, but does mean that one or two parties made a trade and the trade may have moved shares from the holding of one trading desk / brokerage to another.
So when you are talking about anonymous manipulating the pps, I assume all of the above, to the extent it is not mistaken, has been taken into account, right ?
