is there a way to plot ema calculated from high and low in one indicator?

[ESHunter]

Hi,

I'm trying to build an indicator that allows me to plot the ema calculated from close, and also from high and low. So, 3 lines in total, basically an ema channel.

I don't have much programming experience. anyone can help how to do this? thanks

This should be easy enough to modify....

It looks like the link would plot the channel upper/lower bands based on deviation, not on previous period highs and lows, correct? Is there a way to do it from highs and lows, or do you just have to create three moving averages?

Hello,
You could have the plots in the indicator plot off of the Close, High, and Low values.
For example:

protected override void Initialize()
{
    Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "EmaLow"));
    Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "EmaHi"));
    Add(new Plot(Color.FromKnownColor(KnownColor.DarkViolet), PlotStyle.Line, "EmaClose"));
    Overlay				= true;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
    // Use this method for calculating your indicator values. Assign a value to each
    // plot below by replacing 'Close[0]' with your own formula.
    EmaLow.Set(EMA(Low, 20)[0]);
    EmaHi.Set(EMA(High, 20)[0]);
    EmaClose.Set(EMA(Close, 20)[0]);
}

That would plot the EMA Channel that you are referring to. It would be similar to adding three moving averages.
