Thanks, Gordon. I'll give IB a buzz and let the group know.
Suppose I choose the eSignal path: may I do well with a 100 symbols plan (eSignal "Basic")? suppose it takes 5 [Sec] to change the list of 100 stocks programatically, and another Sec to get the "LAST" quote for them all, won't I - using this route - be able to scan those 500 stocks, or even more?
Do you have any idea how much time does it take to Tomasz's eSignal plugin to *programatically* switch those 100 symbols? (I guess the retrieval of quotes is done even in intervals of ticks, which are much smaller than 1 [Sec])
Thanks Again,
Short.

Hi,
You can definitely change the list programtically using the
automation interface. It's pretty straightforward, actually. As long
as the backfill box is not checked, you will only be accessing the
most recent quote in an exploration (you would also have exploration
configured for last 1 quotation). However, I don't know that IB will
allow you to do that. I understand they get fussy when you try to
swap out the symbol set quickly like that. You might want to give
them a call and double-check (and please let the group know what you
find).
Meanwhile, eSignal will do this very easily. You can do all 500 on a
200 symbol plan, and Tomasz plug-in will manage clearing and
changing the symbols for you.
