RE: [amibroker] Creating Chart element from .afl files in Backtest, Scans and Explorer, AmiBroker Email List Archive

Thanks Joe,

I have not used COM objects previously but I will give it a go (after I get a few other things under control)!

Learning a new application such as Amibroker is a big challenge, even when converting from an application with a similar purpose. There are always significant and/or subtle differences.

Regards,

Robert

Robert - I think you'll have to use jScript or VB to drive AB. I didn't fire this up this morning and it may have errors but I'm shipping a clip to give an example how LAYOUTS, TEMPLATES and TABS can be selected from jScript. From the dates in the zoom to range it appears I haven't tried this for a couple of years. It was a test routine and note that I was going for 3 specific stocks.

It's in the manual, of course in the COM object documentation. Good luck finding it.

Hope this helps

Joe

AB = new ActiveXObject("Broker.Application");
AW = AB.ActiveWindow;

for( i = 1000; i < 1003; i++ )
{
Stk = AB.Stocks( i );
WScript.Sleep( 2000 ); // 2 seconds delay
Doc = AB.Documents.Open( Stk.Ticker );
   if(AB.LoadLayout("C:\\Program Files\\AmiBroker\\AFL\\Composites\\Holdings.aly"));
   {
   WScript.Echo("Load Layout Successful");
   }
   if(AW.LoadTemplate("HIA.aly"));
   {
   WScript.Echo("Template Load Successful");
   }
   AW.SelectedTab=1; // Switch to tab 0,1,2,3

   if(AW.ZoomToRange("2006-1-3","2006-3-7"));
   {
   WScript.Echo("Zoom Successful");
   }

   AB.ActiveWindow.ExportImage(Stk.Ticker + ".png")
   WScript.Sleep( 2000 ); // 2 seconds delay

Doc.Close();

}

Subject: [amibroker] Creating Chart element from .afl files in Backtest, Scans and Explorer

I am new to Amibroker and to this forum, but with considerable
experience with both Wealthlab Developer and Metastock.

I am attempting to build some integrated afl scripts (as templates)
that work accurately in Backtest, Scan and Explorer modes.

The greatest difficulty I am experiencing is generation of multi pane
charts from within the afl script. I find I can generate signals and
indicators to be written on an existing chart but I cannot call up
either a stored layout or template.

I am most probably missing something. Can someone put me on the right
track? What is the best way to generate or manage a complex chart
from within an afl that accurately represents the current state of
Backtest, Exploration or Scan?

Robert
