Need Help with Bollinger Indicator

[omermirza]

I'm getting an error at this part of the code:

protected override void OnBarUpdate()
{
if (CurrentBar > Period)
{
//bhigh = MAX(High, 150)[0];


bandwidth = (Bollinger(Deviation,Period).Upper[0] - Bollinger(Deviation,Period).Lower[0])/SMA(20)[0];
bulge = MAX(bandwidth(0), 150)[0];

Plot0[0] = (bandwidth/bulge)*100;


}
else {
Plot0[0] = 0;
}
}

The error is bandwidth is a field but used as a method. Any ideas?

Hello omermirza,

That would be this line:

bulge = MAX(bandwidth(0), 150)[0];

You likely need:

bulge = MAX(bandwidth, 150)[0];

That's what I had before but I do get the attached errors if I write it like that.
Variables are defined as follows:

private int bulgelength=150;
private double bulge;
private double bandwidth;
private double bhigh;

Hello omermirza,

MaX takes a series, you would need to make a series<double> and not a double.

The code you are getting an error with is trying to get the max of 1 data point named bandwidth.

You can find samples of using a series here: https://ninjatrader.com/support/help...t8/seriest.htm
