It's all cheato...
They advertise for cheap rates if routed via their so called SMART route,
but if you make use of it then your order does not get filled, or get filled only if it is to your disadvantage (ie. filled only if the market price goes against you,...)
CHEATO! I SAY! CHEATO!
Quote from MTE:
Just take your medicine and go back to fighting those imaginary wars with market makers on your demo platform.
you say SMART, but after sending it out it says CBOE, priceless! 
Quote from IB Salvatore:
Traderum,
Unmarketable Smart routed orders have to rest on an exchange. Just because you see CBOE doesn't mean the order will stay on the CBOE.
Smart means IB will pull the order off the exchange it is resting on and get it to an exchange where the order is marketable if that happens.
You could never manually reroute your orders as fast as our software plus our software considers maker taker fee's when multiple exchanges are on NBBO. Another factor that would make manually routing much slower and reduce your fill rate.
The below links explains exactly how it works and will explain what you see on your Work Station.
