Distance between SMA and EMA lines

[Kal33]

How do I create a line on my chart that plots the changing difference between an SMA and EMA line (both the SMA and EMA will have the same time periods)?

Hello Kal33,

Thanks for your post.

The AddPlot() method could be used to add a plot to your script.

You could then assign the plot a value of the SMA minus the EMA to plot the difference between those two indicators on a chart. For example, the code might look something like this.

//OnStateChange() section
if (State == State.SetDefaults)
{​
    // Adds a blue line style plot
    AddPlot(Brushes.Blue, "MyPlot");​
}

//OnBarUpdate() section
protected override void OnBarUpdate()
{
    MyPlot[0] = SMA(20)[0] - EMA(20)[0]​;
}​

See the help guide documentation linked below for more information and sample code.

Let me know if I may assist further.
