Re: [amibroker] AmiBroker, ^NDX, and TRIN

Hi Steve,

No, nothing in Amibroker tells directly us the components of an index
symbol, like Yahoo's ^NDX. Indirectly, you could use the AddToComposite
function on the N100 components and produce your own surrogate for ^NDX.

RE: the Nasdqaq TRIN: Quotes Plus, my data supplier, pre-calculates and
produces data for the !-prefixed symbols I use here for my Nasdaq TRIN
indicator:

Tnq=( Foreign("!NQ-A","C") / Foreign( "!NQ-D", "C") )/ (
Foreign("!NQ-AV","C")/ Foreign( "!NQ-DV", "C") );
Plot(Tnq,"NAZTRIN",colorBlack,styleLine|styleOwnScale);
Plot(MA(Tnq,10),"MA(10)",colorRed,styleLine|styleOwnScale);
Plot(.5,"",1,1);
Plot(-.5,"",1,1);
GraphXSpace=3;

HTH,

-john

Is there something in AmiBroker that tells it that
^NDX consists of 100 Nasdaq stocks ?

Does AmiBroker know specifically which 100 stocks
belong to  ^NDX ?

I am wondering, because, otherwise how would AmiBroker know
how to calculate Trin for Nasdaq stocks by using:

TrinIndex =
 ( AdvIssues() / DecIssues() ) / ( AdvVolume() / DecVolume() );


Is it true that, for example, AdvIssues()
is calculated based on a group of stocks,
which is based on a particular Index,
which is based on the market for the stock being viewed ?


Thanks,
Steve
