[amibroker] CBI: bo.InitialEquity to set value not working?

[markhoff]

Hi,

I wonder if the CBI property bo.InitialEquity cannot be used to set
the initial equity. At least for me it does not work and I must use
the SetOption("InitialEquity", ...) command, although the
documentation does not say that the bo.InitialEquity is read-only.

Please see the code below:

--- cut ---

defaultPosSize = 1000;

InitialEquity = 123456;

Buy = Sell = Short = Cover = 0;

SetOption("UseCustomBacktestProc", True);

//SetOption("InitialEquity", InitialEquity);

SetCustomBacktestProc(""); 

// the trading rules
TwentyBarHHV = Ref(HHV(High, 20), -1);
Buy = High > TwentyBarHHV;
Sell = Ref(Buy, -10);
// cleanup excessive signals
Buy = ExRem( Buy, Sell );
Sell = ExRem( Sell, Buy );

if( Status("action") == actionPortfolio )
{
        bo = GetBacktesterObject();

        _TRACE("# bo.InitialEquity (default) = " + bo.InitialEquity);
        _TRACE("# bo.Equity (default) = " + bo.Equity);

        bo.InitialEquity = InitialEquity;

        _TRACE("# bo.InitialEquity (updated) = " + bo.InitialEquity);
        _TRACE("# bo.Equity (updated) = " + bo.Equity);

        bo.PreProcess();

        _TRACE("# bo.InitialEquity (after bo.PreProcess) = " + 
bo.InitialEquity);
        _TRACE("# bo.Equity (after bo.PreProcess) = " + bo.Equity);

        for( bar = 0; bar < BarCount; bar++ )
        {
                for( sig = bo.GetFirstSignal( bar ); sig; sig = 
bo.GetNextSignal(
bar ) )
                {
                        // cash and equity are only correct if SetOption() is 
used to set
InitialEquity
                        _TRACE("# " + sig.Symbol + " : Cash = " + bo.Cash);
                        _TRACE("# " + sig.Symbol + " : Equity = " + bo.Equity);

                        if(sig.IsEntry())
                        {
                                sig.PosSize = defaultPosSize ;
                        }
                }
                bo.ProcessTradeSignals( bar );
        }
        bo.PostProcess();
}

Do you have any idea why bo.InitialEquity cannot be used to write a value?

Thanks in advance and best regards,
