Hello
I have this code:
There is override Plot
Situation is:
1. I save workspace, exit from NT
2. I start NT and i see charts, which is in saved workspace and this indicator on chart, but Plot doesn't override after starting terminal - why?
I have this code:
Code:
public class BackGroundGradient : Indicator
{
#region Variables
public Color CL_1 = Color.DimGray; //Color.Lavender;
public Color CL_2 = Color.Black; //Color.LightSkyBlue;

internal Color Color1;
internal Color Color2;
private DataSeries MAHolder;
private int Period = 42;
#endregion
#region Initialize & OnBarUpdate
protected override void Initialize()
{
Overlay = true;
CalculateOnBarClose = true;
MAHolder = new DataSeries(this);
public override void Plot(Graphics graphics, Rectangle bounds, double min, double max)
{
if (Bars == null)
return;
{
base.Plot(graphics,bounds,min,max);
