Don't believe him Marty (no offense intended Sniper).
(My comments are only relevent to Naz traders as I don't trade listed)
I am a professional (trade own account for a living) who has used MB, Cyber, Tradescape, Tradecast, Protrader, and a few others too useless to remember (actually to useless to forget, but that's another story).
The ECN connections I have on IB are superior to those of my other favorite broker (MB). Sniper is correct that at IB I don't have as many algorithm options available with each ECN as at MB, but I only want direct connection anyway...I don't want anything "working" my order other than my stubby little fingers.
I divide the "interface" into two sections and rate them separately...
A -- Information interface: Beyond bad. Don't even consider trading with their data. Do what IB recommends and get a reliable third party data/charting vendor.(I completely recomment RealTick from Realtick.com)
B -- Execution interface: Quirky, but then after use, you learn that it is actually *better* than some of the popular "pro" apps (like Realtick). For routing I will put myself (using the IB hotkeys and a properly configured page) up against any pro using RT, Cyber, Protrader, etc. and I believe I will beat them. I certainly can say that *I* am faster on IB than on any of those others (I am a scalper where speed matters).
Direct ECN execution speed is every bit as fast as those other "pro" brokers (I still maintain an MB account and use it as a backup) Occasionally an order will get lost or hung, but I've had this problem with every broker I have ever had.
I have found the platform very stable (run it on a nice computer with plenty memory and you should be find).
Customer support is beyond lousy and I've learned to live with it (while I'll learned to live with the $5K per month commission savings).
You'll have to pry IB from my cold dead fingers and if I ever have to move on it will cost me the yearly salary of a very middle class American family.
Marty, you probably can't afford NOT to use IB.
