Title: Help Please: Running AB Scans from Command Line
Dan,
This is only a hunch... I did not do any
testing.
Under Tools, Prefs, Misc., if you have Layouts selected
under "Save on exit", I would try unselecting it.
I hope this helps.

Hi,
To
automate my daily scan and
exploration processing, I’ve created several
JScripts that execute from the Windows command line. The scripts instantiate a new AB object and
then run an AFL file. The scripts work
fine IF AB is running, but fail if AB is NOT
running.
To solve
this, my first solution was to run AB from a .cmd batch file and then
call my scripts. It works, but has some hassles.
My second solution
was to add
“oAB.LoadDatabase()” to my
code. The good news is that my JScripts now work
without having to run AB separately. (Test code below.) But…
The bad
news is that my AB
default layout gets deleted! I.e., after I run the command line Jscript and
then open AB manually, my default layout is gone!
Overall,
is this the best
approach to automate scans and
explorations?
Do you see any bugs in the code below?
Thanks in advance for any
help.
Regards,
Dan.
var
sDBFileLocation = "C:\\Program
Files\\AmiBroker\\QuotesPlus_Stocks";
var oAB,
oAA;
//Create AB
object
oAB = new
ActiveXObject("Broker.Application");
//Load
DB
if(oAB.LoadDatabase(sDBFileLocation) == true)
{
WScript.Echo("DBLoaded");
}
oAA =
oAB.Analysis;
/* load formula
from external file */
oAA.LoadFormula("C:\\Program
Files\\AmiBroker\\Formulas\\Systems\\Test.afl");
oAA.ClearFilters();
oAA.Filter( 0,
"watchlist" ) = 1;
/* set apply to
and range */
oAA.ApplyTo = 2; // use
filters
oAA.RangeMode = 2; // use
last day's quotes
oAA.RangeN =
1;
/* run backtest
and display report */
oAA.Explore();
oAB.SaveDatabase();
oAB.Quit();
