    I have an IB account and exclusively trade SPY. When placing a SPY market order, is it preferable to use IB's 'smart' route or is there an exchange or ecn that is typically better than the rest in terms of speed of fill?

  2. FWIW - ARCA market order on QQQ is excellent - but QQQ is much more liquid than SPY, and a tighter B/A.
