Problem with plotting brush colors based on indicator value

[EminiMES]

Not sure what I doing wrong but I am trying to plot different colors based on indicator value being > 0 or < 0. It will only plot red and not green no matter what the value is with the below logic:

protected override void OnBarUpdate()

{
if (Value[0] > 0)

{
Plots[0].Brush = Brushes.Green;
Plots[0].Width = 20;
}

if (Value[0] < 0)
{
Plots[0].Brush = Brushes.Red;
Plots[0].Width = 20;
}
}

Update:

When running the indicator live the color changes work but they change the colors of all the previous days as well. So when the value is greater than 0 it turns all the bars green on the current day as well as all the bars on the previous days. When the value is less than 0 it turns all the bars red on the current day as well as the previous days. I would like for all bars that are greater than 0 to be green and stay green and all the bars that are less than 0 to turn red and stay red.

Hi EminiMES, thanks for writing in. The PlotBrushes[][] is the proper array to use to change individual plot colors. I attached an example for reference.

Kind regards,

Tried the following and it didn't work... guess there is more to it than that.

protected override void OnBarUpdate()

{
if (Value[0] > 0)

{
PlotBrushes[0][0] = Brushes.Green;
}

if (Value[0] < 0)
{
PlotBrushes[0][0] = Brushes.Red;}
}
}

Hi Emini, Please use Print(); to print out the value of the Plot, and to see if the condition is becoming true:

Print(Value[0]);
if (Value[0] > 0)

{
    Print("Setting Plot to Green");
    PlotBrushes[0][0] = Brushes.Green;
}

if (Value[0] < 0)
{
    Print("Setting Plot to Red");
    PlotBrushes[0][0] = Brushes.Red;}
}
}

Also, make sure you are performing this code after Value[0] is set, and check the Log tab of the Control Center for any errors.

Kind regards,

It's working fine now... not sure what the issue was but I logged out and logged back in and it worked using PlotBrushes.
