The simplified code below runs without any syntax error. However, instead of optimizing through all 100 steps, it only does a single step. Any idea why doesn't it do all 100 steps, as coded in the Simple MA Cross afl?:
//----------------------------------------------------------------------------
// AUTOMATION CODE: Load an AFL and Run a Portfolio Optimization
//----------------------------------------------------------------------------
EnableScript("jscript");
<%
database = "C:\\Program Files\\Amibroker\\Data";
formula_1 = "C:\\Simple MA Cross.afl";
AB = new ActiveXObject( "Broker.Application" );
AB.LoadDatabase( database );
AA = AB.Analysis;
AA.LoadFormula( formula_1 ); // load formula from external file
AA.ApplyTo = 1; // use current symbol
AA.RangeMode = 3; // use 'From' and 'To' dates
AA.RangeFromDate = "11/01/2005";
AA.RangeToDate = "12/31/2005";
AA.Optimize( 0 ); // run Optimize for the portfolio, which is just one symbol
//AA.Backtest();
%>
//---------END AUTOMATION AFL-------------------------------------------------
