i know with fido <online> i can check at the time of the trade .. which mm/ecn the trade is routed thru
-- unfortunately .. i wasn't tipped off to nite's totally manipulative ways .. until dec of 2008 ~ both techs at my <then> 2 level 2's informed me of their known *behavior* patterns ..
i do now .. i've talked with fido <re: nite in the last month on another stock> apparently *most* are in on their dirty little secret
curious to know who was used originally .. last year by fido
may be worth it .. for me to make a call and see if they keep that via their records ~
