Region Fill Not Working as Expected

[daven]

I am trying to bring over an indicator I have in NT7 to NT8, but the RegionFill command is apparently not working the same as it does in NT7. The code I wrote is intended to color a region between a faster moving average line and a lower moving average line, cyan if fast line if above slow line, and light pink if fast line is below line. Here is the code that is supposed to do that:

// private Series<double> mid;

AddPlot(Brushes.Chartreuse, "H_Avg");
AddPlot(Brushes.OrangeRed, "L_Avg");
AddPlot(Brushes.Aqua, "Max");
AddPlot(Brushes.DarkMagenta, "Min");
AddPlot(Brushes.Yellow, "MidLine");
AddPlot(Brushes.Black, "TrendLine");
}
else if (State == State.Configure)
{
max = MAX(High, Period_M);
min = MIN(Low, Period_M);
mid = new Series<double>(this);
}
}

protected override void OnConnectionStatusUpdate(ConnectionStatusEventArgs connectionStatusUpdate)
{

}

protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
{

}

protected override void OnBarUpdate()
{
if(CurrentBar < Period_B)
return;

double max0 = max[0];
double min0 = min[0];
mid[0] = (((max0-min0) * 0.5 )+ min0);

H_Avg[0] = SMA(EMA(High, Period_B), Period_S)[0];
L_Avg[0] = SMA(EMA(Low, Period_B), Period_S)[0];
Max[0] = max0;
Min[0] = min0;
MidLine[0] = SMA(mid, Period_S)[0];
TrendLine[0] = EMA(Median, 2*Period_M)[0];

if(MidLine[0] > TrendLine[0])
{
Draw.Region(this, "Cloud1" + CurrentBar, CurrentBar, 0, MidLine, TrendLine, null, Brushes.Cyan, 30);
}
else if(MidLine[0] <= TrendLine[0])
{
Draw.Region(this, "Cloud1" +CurrentBar, CurrentBar, 0, MidLine, TrendLine, null, Brushes.LightPink, 30);
}
}

I've also attached a screen shot to show you what it actually is doing.
What am I doing wrong in the code?

Been a whole day and no one has responded to this message. Is there an issue with the way I posted it?

hello daven,

Thanks for your post and patience.

I am reviewing and will respond later today.

Hello daven,

Thanks for your patience.

The issue is the use of CurrentBar as the startbars ago value. Because CurrentBar is the bar count the farther you go to the right edge the larger the CurrentBar value is. So in Draw.Region you are telling it to start coloring basically from the beginning and the consequence is that you are constantly overlaying the regions.

I'm not sure what you wanted to do but if you use 1 as the start bars ago and 0 as the endbars ago then the regions will paint as expected relative to the direction of the lines.
