If you are using external JScript, you can use
try
{
}
catch( e )
{
}
to catch any run-time error on JScript side.

Subject: Re[2]: [amibroker] About "Out of present range" OLE error
This error is a real pain to work around... it hardly ever occurs at the same time, sometimes the code works fine for a week and then it occurs again in the middle of an 30 minute procedure. I inspected my JScript-log and all the arguments for all AmiBroker OLE calls look good. I suspect the error occurs when the AA encounters a ticker that has bad data for a specific date-argument.
I test over 1000 tickers and I cannot predict combinations of portfolio composition, ticker selection, and trades. Also I don't want to exclude a ticker just because it has a few bad data.
Does anyone have any suggestions?
