Indicator Data Series

[NinjaTrader_AlanP]

Hello kiss987,

To pass a series other than the primary series to an indicator you would use Highs[1] or Lows[0], for example SMA(Lows[1])[0], would be passing the low series of the secondary series added to a script
.
I have provided a sample script which will print the highs and lows of the 1st, 2nd, and third series added to the script.

You could also see under Multi-Time Frame ISeries,

Hi,

Simple example:

if (State == State.DataLoaded)
{
avg = new Series<double>(this);
}


protected override void OnBarUpdate()
{
avg[0] = (High[0] + Low[0]) / 2;
}

Hello kiss987,

So I may provide you the best answer, would you be able to provide a sample indicator which takes two inputs?

I look forward to your reply.

Thank you for your reply.

The RSI indicator uses only one data series as an input (Closes[1] in the example), so there's no problem.
However, what if my custom indicator needs more than 1 input. For example, both Highs and Lows values.
When my indicator takes the data from the chart directly there's no problem because I can simply use the High[x] and Low[x[ values, however I don't know how to get those values when I don't use the chart as a data series.

Hello kiss987,

Thank you for your note.

I’ve attached a sample which will print to the output window the RSI of the secondary series added to the strategy which is a 1 range series.

You would want to use the RSI Syntax which includes the ISeries, which is how you pass the indicator the secondary series.

I want to get the values of an indicator from a different data series which I run on.
For example, my strategy is running on a 10 range chart but I want to get the RSI values from a 200 range.

Thanks
