Every time I look at futures with the time and sales screen in TWS i see double counting of trades. wtf is going on. its been like that for months at least.
some other day i was trying to collect the data for some nasdaq stocks from TWS via API and i notice a lot of double transactions as well. in TWS T&S they represented as one transaction... go figure...when i'm working on this project , few times i visually notice difference in quotes between IB's TWS and MB trading platform.in favor of MB..
