[amibroker] Re: AdvIssues + DecIssues not working?

["brian_z111" <brian_z111@xxxxxxxxx>]

Hello Ed,

I get the same as you (no report for Out_Stix in an AddColumn.

There is something I don't understand about this - I think it is to 
do with the way the Add/Decs are calculated "behind the scenes" (as a 
composite).

Using variations of the following code I can get the Ads, Decs and 
Ad/Decs to fill a column, or to plot but then it breaks down at the 
final EMA line.

I can plot Ads,Decs or Ad/Decs and drag an EMA onto the Ad/Decs line 
in the  indicator window (see code at SECTION_BEGIN) but as soon as I 
plot EMA(AD,Periods) the EMA plot goes missing.

Filter =1;

Period = 21;

Out_STIX = EMA(100 * AdvIssues()/( AdvIssues() + DecIssues() ), 
Period);

A = AdvIssues();
D= DecIssues();
AD = AdvIssues()/( AdvIssues() + DecIssues() );
EAD = EMA(AD,21);

//Plot(A,"Ad",1,1);
//Plot(D,"Dec",1,1);
Plot(AD,"AddDec",1,1);
//Plot(EAD,"EMAAddDec",1,1);
//Plot(Out_Stix,"OutStix",1,1);


AddColumn(A, "Add",1.2,1);
AddColumn(D, "Dec",1.2,1);
AddColumn(AD, "AD",1.2,1);
AddColumn(EAD, "EMAAD",1.2,1);

AddColumn(Out_STIX, "STIX",1.2,1);

_SECTION_BEGIN("EMA1");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 200, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", 
colorCycle ), ParamStyle("Style") ); 
_SECTION_END();
