I too would like to evaluate trades on the bid/ask. I've never used Quotetracker, is this the same tool that used to be Medved Quotetracker, a 3rd party freebie from the IB website? I have tried Market Delta which I previously mentioned on this list when we were discussing volume.
HOWEVER, if IB is just providing a 3 second snapshot (or whatever it is) and not true tick data, how would it be possible for anyone, including Market Delta to accurately provide information on whther a trade occurred on the bid or ask???? That is the question that prevented me from even trying to code an indicator of this sort. I don't believe it would be possible with IB.

Here is Marcin's reply: "Natively it's not possible to store bid/ask prices in AmiBroker database, so the only workaround would be to catch Bid prices in the LAST field when using DDE plugin. Alternatively - please search for an engine that will allow you to store the quotes in the SQL database and then - use ODBC plugin: http://www.amibroke r.com/odbc. html" On Fri, 22 Dec 2006 12:58:52 -0500, Charles J.
