Subject: [amibroker] how do you use addtocomposite?
> First, is there a symbol in the AmiQuote data sources that will give
> the advance and decline values of the NYSE on a daily and historical
> basis? If so I would not have to search the AmiBroker database.
>
> I am trying to scan the NYES in AB to find the number of advancing

>
> Dec = DecIssues();
> AddToComposite(Dec, "~CumAD", "L");
> Adv = AdvIssues();
> AddToComposite(Adv, "~CumAD", "H");
> delta = Adv - Dec;
> AddToComposite(delta, "~CumAD", "C");
> Buy = 0; // required by scan mode
>
> After I run this I look at "~CumAD and nothing is present but the
> ticker and date. All other fields have 0. I use a filter Market =
> NYSE and all other fields blank. I also added Group = Stocks, but
> neither filled the ~CumAD fields.

> Since the AddIssues and DecIssues returns an array do I need to use
> a loop to go through the arrays and add the fields to ~CumAD? If so
> what would the loop look like? For loops need to know how many

> of entries in the arrays returned. In C++ I would use GetSize but I
> do not see that in AFL. Does BarCount serve the same function? Does
> BarCount care whether you a subset of the database, set the scan to
> search only specific date ranges?
>
> Once I build the ~cumAD say from 1970, how would I add entries
> daily, just change the date range to one day and scan?
