Are there any 3rd party software programs that can integrate with IB's level 2 box? For example, I would put 'MSFT' in an IB level 2, and a chart and time&sales (from eSignal, or whoever) would automatically change to MSFT? I would use the level 2 of the 3rd party software, but it seems none of them have integrated ecn books, or they're difficult to trade from.
There is no way that 3rd party software can be linked to a TWS Level II window since IB API does not provide that capability. You can view IB Level II within the 3rd party software such as QuoteTracker: http://www.quotetracker.com/ and then link the T&S and chart windows to the Level II window.
I would use QuoteTracker, but: It takes 5-10 seconds for a level 2 box to load quotes. I can't find a way to click in a level 2 box, and have the symbol show up in the order bar. It's not very easy to place a trade from your level 2. Can both of these issues be solved?
Time to switch symbols - will check on it. Trading - You can set QT so that when you double click on BID/ASK/LAST on the Level I quote, or on the bids or asks in the Level II, the trade panel will be filled in accordingly. To set that, go to OPTIONS/Edit Preferences menu, TRADING tab and check the box on the bottom left for "Double-click on Bid/ Ask/Last invokes Trading"
Please email QT support and include URL for this post. Will get you an update that should resolve this issue.
