I thought it would be worth adding a recent experience to this thread...
Namely some issues I had running 64 bit AmiBroker and 64 dll's on a Mac Pro
running Win 7 x64 under BootCamp.
As TJ knows, I was seeing very clear evidence that my 64 bit versions were
running slower than the 32 bit equiva
Hi,
my understanding is this:
barcount counts all the bars in the chart (not just visible);
so, i have written
printf("bars in the chart:"+barcount);
it's giving different number of bars when zoomed in and zoomed out.
Does barcount look at visible bars only?

Dear members,
Can someone shed light on what barindex is and how it can
be used to access volume bar 10 periods ago? I am writing a function
to find highest 5-min volume for the last 5 days till yesterday's close.
Thanks in advance,

With the way AB works, the implications of ChartIDs being the same or
different can be profound.
Once one acquires some insight into the ChartID concept, the desire to
be able to do copies of panes/layouts/templates and have control over
whether the copies have the same or new ChartIDs comes to
It's amazing what a good night's sleep does for a little perspective.
Of course these functions only look back from the right edge of the chart - and
do not produce full arrays. Thus, they are of very little use.
That will teach me to try to be creative at 1 in the morning

Hi,
Many topic about that. I kept these lines in my AB bible.

Barcount vs BarIndex()
BarCount is a numeric variable that holds just one number (the count of
elements in array).
On the other hand BarIndex() is a function that returns ARRAY
representing consecutive index of each
Take is easy, Rick.

Can anyone tell me the mathematics of the Wilders function?
I find I am using it in formulas with out a firm grasp of how it is calculating

Chris,
Just do a quick Google search for questions like this.
Here is the first hit:

Welles Wilder's indicators, including Average True Range do not use the

Thanks for the reply. I will post my problem directly. I am trying to find
the highest 5-min volume bar

Hi,
one more point. I am good at Excel vba and I was able to do
this in Excel like this.
=max(volumerow5daysback:volumerowtillyesterdayclose) where volume
is 5min volume in each row of Volume column.

Hello,
I just installed a clean upgrade of Windows 7 64 bit as a new virtual machine
in Parallels on my Mac Pro. I also have an XP 32 bit virtual machine that I
was upgrading from which contains my AmiBroker folder with all the associated
files.
I did a full install of AB 64 bit on the new VM

In the phrase "for (i=startbar; iendbar can be arrays. I believe that, so far, both of them are arrays.
You might want to redefine startbar and endbar to be something like this:
startbar =
LastValue((Lookbackperiodindays*6.5*units)+nbarssinceopen(intradaytimeframe));
endbar = LastValue

I tried to do individual optimization on a number of scrips in a

While the optimization is done correctly, the result is not exported to the

Also, in the display,

When you do a full install (not an upgrade), AB first asks where to
install AB, and then asks where to install support files (including all
.afl code, data bases, etc.). Ideally, you would put AB32 in one
folder, AB64 in a second one, and AB support files in a third. The AB

I think your pain is different than mine:) I like the way templates (and
ChartIDs) work currently. It is easy to edit and manipulate them at will.
I use the same formula with two different ChartIDs to be able to have different
sets of parameters for them. But a lot of my studies need to be du
Hello,
For what is worth, on my machine 32-bit AB is installed into
F:\AmiBroker
directory, while 64- bit is installed into
F:\AmiBroker64
directory. As you can see none of them are "Program Files".
With regards to "sharing" files - technically all files can be used by both

Thanks for the suggestions.
I created a new F: drive. I created 3 full installations called Amibroker32,
AmiBroker64, and AmiBrokerData. I copied my old installation folder from my XP

I did not see anyplace where I could specify a "supp

if the opposite happens,score is negative,
price cross below 20ma= -20 points
price cross below 50ma = -35 points
21 matches
