Waterhouse tops Ameritrade on Executions

It's happened before. This time I sent Ameritrade a note ...

Entered an order to buy 2000 CGIH at 4.90 at 10:17am. No execution even as 1000's of shares traded in subsequent minutes below my limit price. At 10:18am I enter the same order in my Waterhouse account and it executes immediately. At 10:23am I enter another order at Waterhouse to buy 2000 CGIH at 5.00. 500 shares execute immediately at 4.99 and the remaining 1500 at 4.98 at 10:25. In the meanwhile I entered another order at Ameritrade at 10:24 to buy 2000 at 5.00. No execution, yet 40000 shares trade at or below 5.00 over the next 3 minutes. This type of thing has happened before. What's going on ? Are you not routing the orders efficiently ? Are you favoring certain market makers over others ? Should I be trading at Waterhouse more often ?
