Super Simple Indicator keeps on loading om some timeframes

[SuneSorgenfrei]

Hi
I have a super simple indicator I hace placed on 4 charts, but some of the charts it seems that eventhough the data are there the indicator keeps on loading.
I need to close the window and create a new one then it works again until I change symbol then it crashes again sometimes please see attached image.
I use Interactive Brokers as the data provider.

public class TheStratScenarios : Indicator
{
private string scenario;
private SolidColorBrush scenarioBrush;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "TheStratScenarios";
Calculate = Calculate.OnBarClose;
IsOverlay = true;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;

//Setting Default Colors
ColorIB = Brushes.Gold;
ColorTrend = Brushes.White;
ColorOB = Brushes.Red;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
if(CurrentBar==0)
return;

string scenario = GetScenario();
//Draw.Text(this, CurrentBar.ToString(), scenario, 0, Low[0] - (Low[0]/150),scenarioBrush );

Draw.Text(this,CurrentBar.ToString(),false,scenari o,0, Low[0], -80, scenarioBrush, new SimpleFont("Verdana",12), TextAlignment.Center,Brushes.Transparent,Brushes.T ransparent,0);
}

private string GetScenario()
{
string scenario = "0";
if(High[0] <= High[1] && Low[0] >= Low[1])
{//Inside Bar
scenario = "1";
scenarioBrush = ColorIB;
}
else if (High[0] >= High[1] && Low[0] >= Low[1])
{
scenario = "2u";
scenarioBrush = ColorTrend;
}
else if (High[0] <= High[1] && Low[0] <= Low[1])
{
scenario = "2d";
scenarioBrush = ColorTrend;
}
else if (High[0] > High[1] && Low[0] < Low[1])
{
scenario = "3";
scenarioBrush = ColorOB;
}

return scenario;
}

Hello SuneSorgenfrei,

Thank you for your post.

The glaring issue I see in your script is that you're referring to SolidColorBrush but using predefined WPF brushes, and I don't see that you're properly serializing the brushes. I suspect the errors you're receiving likely have to do with that. Here's the revisions I would suggest:

public class TheStratScenarios : Indicator
{
private string scenario;
[B]private Brush scenarioBrush;[/B]

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "TheStratScenarios";
Calculate = Calculate.OnBarClose;
IsOverlay = true;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;

//Setting Default Colors
ColorIB = Brushes.Gold;
ColorTrend = Brushes.White;
ColorOB = Brushes.Red;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
if(CurrentBar==0)
return;

string scenario = GetScenario();
//Draw.Text(this, CurrentBar.ToString(), scenario, 0, Low[0] - (Low[0]/150),scenarioBrush );

Draw.Text(this,CurrentBar.ToString(),false,scenari o,0, Low[0], -80, scenarioBrush, new SimpleFont("Verdana",12), TextAlignment.Center,Brushes.Transparent,Brushes.T ransparent,0);
}

private string GetScenario()
{
string scenario = "0";
if(High[0] <= High[1] && Low[0] >= Low[1])
{//Inside Bar
scenario = "1";
scenarioBrush = ColorIB;
}
else if (High[0] >= High[1] && Low[0] >= Low[1])
{
scenario = "2u";
scenarioBrush = ColorTrend;
}
else if (High[0] <= High[1] && Low[0] <= Low[1])
{
scenario = "2d";
scenarioBrush = ColorTrend;
}
else if (High[0] > High[1] && Low[0] < Low[1])
{
scenario = "3";
scenarioBrush = ColorOB;
}

return scenario;
}
