Actually, I've had as many as 900 symbols collecting real-time data in a
different machine. Of course, the tick count averages out to normal on that
many symbols.
As to why DDE, well, I guess it's partly because of the ease of use for
non-programmers like myself. Its possible to do a lot of interesting stuff
with DDE, excel and live data that one can't do once it's already in the
tradestation globalserver.
Can anyone shed some light on the possible cause of a single "beeeeep" every
minute or so comming from a computer that crashes?
I read somewhere that maybe its faulty memory?
