Assigning A Value To Swing Points to call in a strategy

[BullyWig Trader]

Hello all.

I am looking for a simple swing indicator that returns a value that can be called in the strategy builder for the following swing conditions.

HH: higher High (2)
LH: lower high (1)
LL: lower low (-1)
HL: higher low (-2)

Below is a visual of what I am talking about in the above table with values at each swing point.
I do not need the actual value to print on the chart itself.
The only purpose is to pull that value when creating a strategy.







At any given time, whichever of the 4 above conditions exist as the last printed swing condition, I would like a value assigned until the next swing condition prints on the chart. So for example, if we printed a new Higher High condition on the chart, a value of 2 would be the result for all future bars, until the condition was changed upon the next swing. I need to call a value like this for a strategy I have in mind. I hope this makes sense, and that you can point me in the right direction. Thanks in advance if anyone can help out.

Hello BullyWig Trader,

"I am looking for a simple swing indicator that returns a value that can be called in the strategy builder for the following swing conditions."

The Desktop SDK documentation provides sample code of calling the Swing() indicator.

https://developer.ninjatrader.com/docs/desktop/swing

For an indicator to be usable in the Strategy Builder, a plot must be added with AddPlot(), the plot series must be returned in the getter of a public Series<double> (using the XmlIgnore attribute), and the value you are sending to the host would be assigned to the plot series Value[0] / Values[plot series index][0].

The support article below provides sample code.

"I do not need the actual value to print on the chart itself."

Prints to the NinjaScript output window are helpful for debugging when developing your custom indicator. We do recommend you use these during the building process, and then remove them once you are certain the code is working the way you intend.

Below is a link to a support article on adding debugging prints to understand behavior.

On each new bar start by assigning the current bar's plot series value to the previous bar's value to carry the value forward.
Then your custom condition can update the value when necessary.

if (CurrentBar < 1)
return;

// assign the previous bar value MyPlotSeries[1] to the current MyPlotSeries[0]
Value[0] = Value[1];

if (/* your custom conditions here*)
{
Value[0] = 1; // assign your value here. for example a 1 could mean the conditions are true and a 0 could mean the conditions are false
}
