IDataSeries with User Defined Methods

[ScottB]

Hi,

I feel like I have seen an answer to this question in the forum but for the life of me, I can't find it.

I have some code I use over and over and currently have it in an indicator. Now I need to make changes that I would prefer to have as a User Defined Method.

If I pass in a secondary BarsArray i.e. BarsArray[1] and in the method accept an IDataSeries parameter i.e. public void SomeMethod(IDataSeries dsBase, int length)

how do I reference the individual components of the BarsArray Open, High, Low, Close, Time?

I want the values associated with the BarsArray i.e. if it were a 5 minute bar for Time, I would get 1205 whereas if I then called the same method with a 60 minute bar, I would get 1200 because that would be the last full bar.

I would ideally like the equivalent of dsBase.High[1] and dsBase.Time[3]

Thanks in advance.

Hello,

You can pass data series but it only passes one of those at a time.

This should clear it up for you: http://www.ninjatrader.com/support/h...dataseries.htm

So if you needed, High, low, open, close. You would need to have a method with 4 parameters and 4 data series passed into it.

Brett, that is the conclusion I had come to but hoped to get a way around that. So I need to pass in 5 DataSeries, OHLC + Time?

Out of curiosity, why can you pass in a BarsArray if it only uses one of the values it provides (presumably Close)?

Best Regards,
Scott

You would access BarsArray though:

Highs[1];
//Outputs a iDataSeries for thte Highs in BarsArray1

You include an s to indicate your accessing another BarsArray then the primary.

If you want to output the high price of the secondary BarsArray from the current bat:

Highs[1][0];
//Outputs a double for that bar index and bars back.

Let me know if I can be of further assistance.

Brett, thanks for the reply. I understand it on the passing side, I was referring to the UserDefinedMethods side. MyMethod(IDataSeries ds1...

Hello,

Yes if you pass it simply defaults in a iDataSeries which would then be the first data series in the BarsArray which is simply Close.
