What about nLastValid on startup of the plugin , which is always -1.
How does it know which is the last bar updated and which bar to update
next. Even on exiting the Preferences menu nLastValid is set to -1
when GetQuotes is called.
Help TJ.

Hello,
It is not always -1. Once you feed the data it won't be -1 anymore
and if local data storage is set to enabled (IMPORTANT!) it will stay > 0 between runs.
Use QuoteTracker plugin source code included in the ADK.
LastBar update date is the datetime of Quotes[ nLastValid ]
(provided that nLastValid > 0 )

Dear friend
Forget Vista and switch back to XP. I too got a new Laptop with Vista. None
of my realtime software worked. Some bug or the other. So I bought a XP home
edition, partitioned my hard disk, loaded XP in C Drive and Vista in D
Drive. It became a dual boot with XP as default on boot up screen. When all
glitches are removed, will switch back to Vista and uninstall XP

Thanks Tomasz. I have no no loops. No complex indicators.
Just a lot of timeframe expands.
I will try the AFL timing and see. If I am unable to find out I will send it to support.
I have no doubt that AFL is the fastest out there. I have been using amibroker since 2004 and I love each and each every day of my experience with it.
Its just that I am perplexed why the CPU would get bogged down like this.
Thanks again.
Will try the AFL timing you and Herman put together.
Cheers,Padhu

Subject: Re: [amibroker] Amibroker High CPU Utilization-anyone else seeing this?.
That's simple:
one of your formulas is very badly coded - and it eats the CPU.
Under normal circumstances the CPU floats in 8..20% use.
You need to use Tools->Preferences->Miscellaneous and check "Display chart timing"
then watch the timings each chart is showing.
All built-in formulas execute well below 0.1 second and this should be your target.
If any formula needs more than 0.5 sec to execute it is badly written and it should not be used.
You must either rewrite it or send it to us and we will tell you what is wrong.
But again: any formula that executes in more than 0.5 sec is NOT to be used in real-time
and requires either rewrite or removal.

Folks:
Attached is the task manager output when Amibroker 4.90.5 is runnning. It always spikes back and forth and stays very high near 90-100% . process shows broker.exe spiking.
I have only 6 charts attached.
I have noticed this in the past when I had indicators attached to more than 8 charts. Now I have only 6 six. Other than 1 , all other indicators are all fairly simple...no looping etc..But uses timeframe expands from daily etc.

Hello,
Send the code to support. Lot of timeframeexpands does not tell too much. Lots means hundreds or tens?
There should be no reason to put more than few timeframeexpand in the code. If you need something from daily
timeframe - calculate everything you need in daily timeframe and then expand the FINAL result ONCE.

One easy way to see if the CPU hog is AB or not, minimize AB.
If CPU usage drops significantly, it is AB.

Another possibility - assuming it is Windows XP, bring up Task Manager and sort the Processes by the "CPU" column.

Hello,
How many times I have to explain that in ANY program that allows custom formulas,
the USER can write formula that will executed slow. And this is exactly what is happening.
The USER wrote the formula badly and I offered him help in fixing HIS formula.
Any formula can be written so bad that it will execute 1000x slower than it should.
I can take Visual C++ or Assembler or any language and I can demonstrate that I can write
the code that will take one hour, month or year to execute. And this has ABSOLUTELY NOTHING
to do with the language you are using.
So it is not AB.
It is THE USER who controls it.
Any formula that is shipped with AmiBroker executes well below 0.1 second and causes less than few percent CPU load.
AmiBroker runs at PHENOMENAL speed !
See the example code:
GetPerformanceCounter(1);
for( i = 0; i < 10000; i++ )
{
x = High + Low;
}
NumberOfOperations = BarCount * i;
timeperadd = GetPerformanceCounter(1);
for( i = 0; i < 10000; i++ )
{
y = x / 2;
}
timeperdiv= GetPerformanceCounter(1);
StrFormat("Total Number of operations = %12.12g", NumberOfOperations );
StrFormat("Total time of additions [milliseconds] = %.2f", timeperadd );
StrFormat("Time per one addition [milliseconds] = %.9f", timeperadd/NumberOfOperations );
StrFormat("Number of additions per second = %12.12g", 1000/(timeperadd/NumberOfOperations) );
StrFormat("Total time of divisions [milliseconds] = %.2f", timeperdiv );
StrFormat("Time per one divisions [milliseconds] = %.9f", timeperdiv /NumberOfOperations );
StrFormat("Number of divisions per second = %12.12g", 1000/(timeperdiv /NumberOfOperations) );
On 2GHz Athlon the results are as follows:
Total Number of operations = 18040000
Total time of additions [milliseconds] = 50.25
Time per one addition [milliseconds] = 0.000002785
Number of additions per second = 359021216
Total time of divisions [milliseconds] = 85.39
Time per one divisions [milliseconds] = 0.000004733
Number of divisions per second = 211270320
(Test was performed on 101000 bars data, that accounts for 3MB - which is MORE than on-chip cache size, therefore memory access times were accounted in,
note that tests involve arithmetic operation PLUS two memory reads and one memory write per iteration)
That gives phenomenal speed of
359 MEGAFLOPS (addition) or 211 MEGAFLOPS (division) - where ONE MEGAFLOP is one million of floating point operations per second (including data read/write)
http://en.wikipedia.org/wiki/Megaflop
This is about AS FAST AS this CPU is capable of running.
This is most amazing fact because it proves that AFL when running array operations runs AS FAST AS it would be possible if your code was written directly in MACHINE CODE
(taking into account regular floating point operations, *not* SSE, 3dNow or other SIMD)
In other words AFL has near-zero overhead when running array operations and can be compared with assembly language when running array operations.
As a comparision JScript on the same machine runs at speed of only 0.8 MFLOPS (divisions). That shows that JScript 250 times slower than AFL.
Bottom line: there is simply nothing faster than AFL. So if your formula executes slowly it is your formula bad coding, not AmiBroker.
For the reference I have been running AmiBroker even on low end 133Mhz Pentium IN REAL TIME.
And Amiga version of AmiBroker
was running OK even on 7MHz (yes SEVEN MEGAHERTZ == 0.007 GHz) processor and 1 MB (yes ONE megabyte) of RAM.
AFL engine exactly the same in both.

Tomasz Janeczko

Thanks Tomasz. I have no no loops. No complex indicators.
Just a lot of timeframe expands.
I will try the AFL timing and see. If I am unable to find out I will send it to support.
I have no doubt that AFL is the fastest out there. I have been using amibroker since 2004 and I love each and each every day of my experience with it.
Its just that I am perplexed why the CPU would get bogged down like this.
Thanks again.
Will try the AFL timing you and Herman put together.

That's simple:
one of your formulas is very badly coded - and it eats the CPU.
Under normal circumstances the CPU floats in 8..20% use.
You need to use Tools->Preferences->Miscellaneous and check "Display chart timing"
then watch the timings each chart is showing.
All built-in formulas execute well below 0.1 second and this should be your target.
If any formula needs more than 0.5 sec to execute it is badly written and it should not be used.
You must either rewrite it or send it to us and we will tell you what is wrong.
But again: any formula that executes in more than 0.5 sec is NOT to be used in real-time
and requires either rewrite or removal.

Folks:
Attached is the task manager output when Amibroker 4.90.5 is runnning. It always spikes back and forth and stays very high near 90-100% . process shows broker.exe spiking.
I have only 6 charts attached.
I have noticed this in the past when I had indicators attached to more than 8 charts. Now I have only 6 six. Other than 1 , all other indicators are all fairly simple...no looping etc..But uses timeframe expands from daily etc.

It seems that when AB is not displaying charts (minimized) it is doing
little besides collecting RT data (see attached)

Ouch!
I wasn't blaming AB. I just suggested a quick verification method of which
application is consuming the CPU resources.

I had a lot of "RequestTimedRefresh( 1, False );" in my code.
I reduced them to one and the CPU load came down from 90% to around 10%.

Hi everyone,
I would like to ask if Amibroker has some trading systems built in? I
mean something analogue to Performance Systems which you can use in
Metastock, or I nead to write them in AFL by my self ( or should
download from internet). If there is that kind of option in Amibroker
- please tell me where should I be looking?
Best regards

8a. Information on BATMAN.
Posted by: "Don Lindberg" dlindber@sbcglobal.net lindbergdon
Date: Tue Oct 2, 2007 2:30 pm ((PDT))
For those of you useing BATMAN I have a couple of questions not covered
in the documentation.
First, does AmiBroker have to be open when BATMAN runs a batch, or can
it be closed?
Secondly, If I have an AFL that I have added into BATMAN to run and I
then edit that AFL, do I have to delete and re-enter it in BATMAN. In
other words does BATMAN just keep a pointer to the AFL, or does it keep
a copy of the complete AFL?
Thanks for any information,
Don Lindberg

Don,
Open AB
I have found that AB will open when you engage Batman so I just open it on
my own
Batman keeps pointing to the same ALF. AS long as you keep the same name
and location after the change it will pick up the new formatted AFL

if I can get it work in the custom backtester, then I agree it's
probably a better method.

By the way GP, I didn't realise it was you who wrote the custom
backtester doc, it's helped me a lot on the way to understand custom
backtesting, thanks for your contribution.

IB has a commission structure that distinguishes bewteen "Smart Routed" and "Non Smart Routed" using the API.
Is ibc automatically send order to "Smart Routed" or is the a specific AFL command for it?
