Hi TJ
May I assume you are NOT using XP Home?
I don't have the View->Refresh choice in my
XP Home Task Manager...just Refresh Now and Update Speed(High, Normal, Low,
Paused)

Amibroker with 6-8 realtime charts? - CPU staying at 100% all the time
Hello,
I can not agree with any of those observations. AB
performs just fine in real time mode provided that
one does not use "killer" formulas like on-the-fly-line
composites over hundreds of tickers.
SAR is not that bad. I can run 10 charts with two panes
each Price and SAR simultaneously in real-time without
problems.
I have standard setting of 3 second refresh interval (in
Tools->Preferences->Intraday)
With this setup on my Athlon XP1700 it consumes on AVERAGE
not more than 9% (NINE PERCENT only) of CPU time.
(see attached)
To get AVERAGE CPU usage measure in Windows Task manager
switch View->Refresh interval to "SLOW"
You may be misguided completely by the Windows Task
manager if you set View->Refresh interval to "FAST".
Then it gives you not average but temporary
amounts.
When you switch to "FAST" mode the CPU usage shown will
jump from ZERO to 100% because this is the way
all programs work: if then need CPU - they get the time
slice from the system and execute at MAXIMUM SPEED (100%)
until given task (say refresh) is completed - then
they switch to sleep state (0% CPU) and so on.
So you will get spikes and valeys but it averages to much
smaller value than the spike is.
For example in the 10 chart example I was getting 60%
spikes and much long 0% CPU usage areas.
If you unfortunatelly have written very slow formula
the solution may be just to go to
Tools->Preferences->Intraday
and change
"Intraday refresh interval" from default 3 seconds to
5 or 10 seconds.

Hi Jayson,
AB takes a lot of CPU usage in RT. The most
I'll do is 4 with update every 5 seconds. ... so it has not been as good
as it is for EOD.
I use it in conjuction with eSignal ... not
sure if I can realisticalyy migrate to AB alone...
4 items you might watch for to decrease
CPU load:
- Do not use interpretation window - causes
extra processing.
- Do not use Tooltips - causes extra
processing.
- If you have loops that start at someplace
other than i=0, quick AFL will not help... AB will process all cells at
every bar
- Update screen as little as possible. AB
processes all data every time you update screen
Ara

Hello,
Anyone out there using AB with esignal
realtime with 6 or more real time chart windows open?. I have about 10
Forex realtime charts and I see CPU staying at 100% all the
time....With help
from support I made some modifications to
the code also...But still stays very high....If anyone has seen this
before appreciate your comments.
Thanks.
Cheers,PadhuSend
