Hi all,

I have the following dataseries:

How do I access the individual symbols in the series in code?

Thanks in advance

This syntax would be invalid in WealthScript. It's likely that you're using WealthScript Translator output (unsupported). In this case, I would strongly caution against touching it for the purpose of mixing it with native WealthScript code.

In a pure WealthScript Strategy, however, your code would then become something like this:

Thanks for your quick response Eugene.

I still don't know how to access the individual symbols inside the dataseries "dsSP100".
For example there are 100 individual symbols AA, AAPL, ABT, ... Is there a syntax to specify them or do I need to write a seperate dataseries for each one?

No you don't need to create a separate DataSeries but let's start by answering what are you trying to accomplish in general. This is not clear to me.

I am trying to write a strategy that will take the S&P 100 and calculate how many advancing issues there are in 15-Minute time scale in reference to the closing price of the previous day.

Here is my code so far (I know it's not right yet):

Thanks Eugene very much for the code.

I am not sure it is doing what I want though or maybe I don't understand it.

Is it using the S&P 100? -Because I don't see it referenced anywhere in the code. Also the "Advancing Issues" -Shouldn't it be from 0 to 100?

Obviously, a Bars object or a DataSeries represents just this single symbol. Having just a single symbol for the 15-min S&P-100 is not enough for your task. That's why it makes zero sense to reference it or anything else, just give it a thought.

(And that's why your question was vague initially. Now I answer: you can't access individual symbols in a DataSeries if by that you mean getting access to index components where the DataSeries is associated with some index.)

The code is to be run on a DataSet that consists of the S&P 100 symbols.

Not sure about the last remark i.e. from 0 to 100 - actually, from 0 to the number of symbols having their closing price of the current intraday bar above the previous day's closing price.

Hi Eugene and all,

I need some help with some bug in my strategy. I keep getting an "index out of range" exception when I run it on a time period longer than 8 weeks.

Heres the code:

Any help would be gratefully appreciated.

If you're asking for my help, then I suggest looking at my code above (see reply from 12/4/2010 11:19 AM).
