Subject: [amibroker] IB RT +
Foreign() + 100% CPU Usage
hello group,
i recently ran into problems
with 100% CPU usage running amibroker RT with IB plugin. i wondered if
someone could share some technical insight as to the tech specs needed for
the type of trading i am doing.
here is the
scenario:
i run amibroker pro RT with
the latest IB plugin. i switch between various layouts, which usually have
6 different windows open. one of these windows is my "statistics" formula
which references about 20, sometimes up to 40 different tickers via
Foreign() statements. the formula in itself does not include heavy
calculating (i think), no Cum() or other stuff, just some basic %change
and loads of WriteIf() and AlertIf(). - still it eats up 100% CPU
usage all the time, quite apparently because of all those Foreign()
statements.
what type of machine would i
need to run this type of scenario?
my specs: AMD Athlon 1700+,
256 RAM, Win XP, ADSL 512/128, AB Pro RT with IB, 1min database, chart
refresh at 20sec
specs needed ??
note that AB can actually do
this, my system does not hang up (for 6 and a half hours trading at 100%
CPU though) and i can trade the way i want to. but when switching between
layouts or alt-tabbing to another application, amibroker may take 5-20
secs.
so, what's the way? more
cpu? eSignal? is eSignal plugin less CPU-intensive?
thanks for any
insight,
dirk
