Great commentary limit, thanks.. I must say that in the case of Interactive Brokers' internal trade matching (the "hidden" Timberhill orders that you get filled with) - its the fastest fills I've ever seen on any platform, and a source of extra liquidity - so I'm all for my broker trading against me in that sense.
I prefer the Auto-routing done in my software (ala IB's TWS) as opposed to the routing being done by the ECN (ala ARCA). Certainly the routing being done on the back-end is considerably slower.
