example of working with two existing data series in the chart

[leontancfa]

My use case is to compare the two data series I added to the chart, and highlight when some correlation status breaks.

How do I make the indicator to dynamically get the references or names of the two series in the code?

Or, any example indicator that works with two data series on the chart?

Hello leontancfa,

Thanks for your post.

A NinjaScript indicator is only able to get the values of the primary data series the script is enabled on when adding the indicator to a chart.

To get values from a second data series, you must add a secondary data series to the indicator script by using the AddDataSeries() method.

AddDataSeries(): https://ninjatrader.com/support/help...dataseries.htm

You could then use the PriceSeries collection to access price values from the primary or secondary added series. For example, Close[0] would get the current close price from the primary data series the script is running on. Closes[1][0] would get the current close price from the added secondary data series.

It is important to review this help guide page to understand how to work with Multi-Timeframe/Multi-Instrument NinjaScripts: https://ninjatrader.com/support/help...nstruments.htm

Please let me know if I may assist you further.

thanks. do you have example of getting the name of the Data Series 0? so that I can use the name into the AddDataseries block.

Hello leontancfa,

Thanks for your note.

The name of the instrument does not have to be specified when calling AddDataSeries() if you want to use the same instrument for the added series but a different timeframe. In this case the syntax for AddDataSeries() would look something like this.

AddDataSeries(BarsPeriodType periodType, int period)

Note that you only have to pass in a 'BarsPeriodType periodType' argument and 'int period' argument,. The instrument will use the same instrument as the primary data series.

An example of this could be seen in the sample code of the AddDataSeries() help guide page linked in post # 2.

Let me know if I may assist further.
