Did you come across this user guide... screen image shows where booktrader info can be found http://www.interactivebrokers.com/en/software/tws/twsguide.htm
if you create a booktrader price button on the dom a selection box will open when you hit booktrader price here is a sample on ib sim use the sim a lot to get used to this platform.
Another IB whiner! I've been using IB for over ten years. When I started, I was already senile. Now I have advanced Alzheimer's. If I can do it, any idiot can do it. Perhaps you are in a coma.
Thanks for the suggestion. As I said, I've already done that. Insofar as I can tell, there is no guidance to be found for configuring buttons on BookTrader ... and, again, no explanation of what the "BookTrader" price is. It's an incredibly shabby presentation. I mean, geez ...
Ok, instead of name-calling, how about looking at the attached screengrab and telling me what IB means, in this specific context, by "BookTrader Price" as opposed to "Ask" or "Bid"?
