Referencing Custom Indicator Values

[setardiff]

I've been using a custom example indicator (ExampleMADifferences) provided by you guys that calculates the number of ticks between two moving averages and that value is displayed in text in the top right of the chart.

I'm very much a novice with programming in general, so I was looking if I could get some help referencing that indicator's value in the strategy builder/data box. I believe I need to use the AddPlot function but to be honest, I cannot figure it out.

Ultimately, my goal is to use the indicator within the strategy builder as a condition to enter positions based on the value that the indicator displays on the chart.

I hope this makes sense. Any help would be greatly appreciated.

Hello setardiff,

Thank you for your post.

I recommend checking out this article on getting started with NinjaScript.

Indicators will only be accessible in the Strategy Builder if the indicator contains a plot and a value is assigned to that plot. So you are correct that you would need to use AddPlot().

The Strategy Builder would then be able to access that plot's value in the Conditions and Actions screen.

AddPlot() can be used to add a plot to the script. Then, you could assign a value to that plot by calling Value[0] = 'x', where x is the value you are assigning.

See this help guide page for more information about AddPlot() and sample code: https://ninjatrader.com/support/help...t8/addplot.htm

Let me know if I may assist further.

Thanks Gaby.

I will definitely read through those articles. But just to be sure, given the indicator only displays a number, is that still plottable? As I would think plotting something like a moving average uses the price data in reference to where current price is, but this is simply a numerical value, not related to the price data, so I'm confused as to what would be plotted?

My understanding is minimal at best so I appreciate you bearing with me.

Hello setardiff,

Yes, it needs to be number to be plotted. In particular, the Value collection is a series of doubles.

Whatever value you would like to access from the indicator in the Strategy Builder is what would need to be plotted.
