Composite

And here is a modification of the second code from top of this page using dynamic count of symbols.
I'm gonna ask AmiBroker whether it is the absolute correct way as I'm not working with composites pretty often.

If using it in analysis window then you may also check "pad and align" setting.

Code:

<code>[COLOR=#008000]// Exploration ###################################################################################### 
[/COLOR] 
WL = [COLOR=#800080]0[/COLOR]; [COLOR=#008000]// WL number 
[/COLOR]Periods = [COLOR=#800080]50[/COLOR]; [COLOR=#008000]// MA periods 
[/COLOR] 
category = [B]categoryWatchlist[/B]; 
categoryname = [COLOR=#0000ff][B]CategoryGetName[/B][/COLOR]( category, WL ); 
compositename = [COLOR=#800080]"~PercentAboveMA_Composite_"[/COLOR] + categoryname;[COLOR=#008000]// tilde required at start of comp name 
[/COLOR] 
atcmode = [B]atcFlagDefaults[/B] | [B]atcFlagEnableInExplore[/B]; 
[B]Filter[/B] = [COLOR=#0000ff][B]InWatchList[/B][/COLOR]( WL ) [COLOR=#800040][B]AND[/B][/COLOR] [COLOR=#0000ff][B]Status[/B][/COLOR]( [COLOR=#800080]"lastbarinrange"[/COLOR] ); 

[COLOR=#800040][B]if[/B][/COLOR] ( [COLOR=#0000ff][B]Status[/B][/COLOR]( [COLOR=#800080]"actionex"[/COLOR] ) == [B]actionExplore[/B] ) 
{ 
    [COLOR=#008000]// sum up true conditions 
[/COLOR]    above = [B]Close[/B] > [COLOR=#0000ff][B]MA[/B][/COLOR]( [B]Close[/B], Periods );  
    [COLOR=#008000]// count symbols based on availability of data 
[/COLOR]    count = [COLOR=#800040][B]NOT[/B][/COLOR] [COLOR=#0000ff][B]IsNull[/B][/COLOR]( [B]C[/B] );      
     
    [COLOR=#0000ff][B]AddToComposite[/B][/COLOR]( above, compositename, [COLOR=#800080]"C"[/COLOR], atcmode ); 
    [COLOR=#0000ff][B]AddToComposite[/B][/COLOR]( count, compositename, [COLOR=#800080]"1"[/COLOR], atcmode ); 
} 

[COLOR=#0000ff][B]SetForeign[/B][/COLOR]( compositename ); 
[COLOR=#008000]// calculate percentage above MA   
[/COLOR]percent_above = [COLOR=#800080]100[/COLOR] * [B]C[/B] / [B]Aux1[/B]; 
[COLOR=#0000ff][B]RestorePriceArrays[/B][/COLOR](); 

callcomposite = percent_above; 
[COLOR=#0000ff][B]Plot[/B][/COLOR]( callcomposite, compositename, [B]colorRed[/B], [B]styleHistogram[/B], [B]Null[/B], [B]Null[/B], [COLOR=#800080]0[/COLOR], [COLOR=#800080]0[/COLOR], -[COLOR=#800080]60[/COLOR] );</code> 

 

Thanks all. After reviewing the tools, I chose quantshare.

In my assesment, it came up as the most interesting tool for composites due to the flexibility to handle them without being a code expert. It also has some drawbacks, my concern was about critical size in this software market.

 

The easiest is AIQ or Stratasearch..

Quantshare in my opionion is easier than Amibroker..

Do you want an equal weighted composite as well?
