The choice to switch from a Windows-based platform to a Browser/Java-based platform is a terrible mistake. Serious Direct Access Brokers (MB Trading, CyberCorp, myTrack) offer their clients a Windows-based platform. The Browser/Java platform is slower, less reliable and a Windows resource hog. The only thing I like of the Browser/Java version is the improved user interface. IB should drop the Browser/Java platform and improve the Windows application to make it more similar to the platforms offered by MB Trading, CyberCorp, myTrack. IBâs Pre/After hours quotes are very unreliable. Particularly the "Best" and "Instinet" quotes are almost always wrong outside regular trading hours. If you see an interesting quote on IB during after hours, it is probably a bad quote. This makes trading outside regular trading hours impossible with IB. IB doesnât give you access to all routes on all stocks. On some stocks you will only be able to route to NASDAQ/Instinet, on some just NYSE/Island and so on. Island and most other ECNs now support all listed (NYSE/AMEX) and NASDAQ stocks. I want to be able to choose the Island route on ALL stocks. They should give us access to all routes on all stocks. Stay away until Interactive Brokers solves these problems.
