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
