Why do you require a third-party charting service?

QUESTION: Hello Mike, Thanks for responding so quickly. I've just another couple of questions--do you use the web based IB platform or have you downloaded the app on your desktop? Also, why do you require a third-party charting service rather than using the IB charts embedded in their application? Your answers will likely determine for me whether to plow ahead with IB or continue with Cybertrader, although I am strongly leaning toward IB. BTW, I primarily trade NDQ and SPX minis, coupled with options on the QQQQ and SPY.

ANSWER: I have not downloaded IB platform. It should be decent, but these tend to be a matter of personal comfort. As for their charting, I never gave it a fair shot but wasn't crazy about it. My old ''mentor'' uses Ensign, so I gave it a shot and like it. As an old TradeStation user I guess I became kind of picky. FYI, we trade the same instruments, this might the first in quite awhile. Mike
