{NinjaScript 8} - Fractals on diferent timeframes

[fscabrera03]

Dear all, hope you are fine.
I need to develop a indicator that works independent of a chart timeframe.
I need this (on the same chart):

See 4H fractals
See 1D fractals

No matter the chart timeframe, if a change the chart timeframe I need that fractals (4H and 1D) drawn on the chart.
How can I write that code? Some sample code or idea?
Thank you so much.
Regards

Hello fscabrera03,

Thank you for the post.

To address the core part of your question "I need to develop a indicator that works independent of a chart timeframe." You can see the following documentation for a detailed guide about using multiple timeframes.

https://ninjatrader.com/support/helpGuides/nt8/multi-time_frame__instruments.htm

The concept you are asking about would be to use AddDataSeries to add a secondary series and then use the BarsInProgress property to execute the fractal logic on the added series instead of the primary.

There is a simple example of using BarsInProgress here:

To plot the results on the primary timeframe you could make use of variables to store values which the primary series plots at the primary chart frequency. A very simply example of that would be like the following:

private double currentSecondaryValue; 
protected override void OnBarUpdate()
{
    if(BarsInProgress == 0)
    {
        Value[0] = currentSecondaryValue; //whatever the variable was set to last by the secondary series will be plotted 
    }
    if(BarsInProgress == 0)
    {
        currentSecondaryValue = Close[0];
    }
}

You could repeat this as many times as needed for each secondary series added.

I look forward to being of further assistance.
