gradual opacity for backbrush

[guidoisot]

Hello,
with regard to indicator VolumeSpickeNT8 small body candles are not clearly visible when overlapped by backbrush. I have tried to solve this by modifying the code as follows:
{
//BackBrush = Brushes.Green;
Draw.RegionHighlightX(this, @"longSignal_1 " + Convert.ToString(CurrentBars[0]), 1, 0, Brushes.Transparent, Brushes.Green, Convert.ToInt32(Opacity));
}
But in this way the background color does not exactly overlap to the bar as it was the case before using BackBrush. Is there a way to have selectable opacity for the BackBrush? so that the color is centered on the candle? Thx.

Hello guidoisot,

Thanks for your post.

The Draw methods will draw from the center of one bar to the center of another bar.
The BackBrush method has been designed to be centered on the bar that it is applied to.

You can create a brush and set its opacity as you wish, that brush can then be applied to the BackBrush method.

Here is an example, done in State.Configure:

Brush temp = PanelColorCrossAbove.Clone(); // Create a temporary copy of the user created Brush PanelColorCrossAbove
temp.Opacity = BackgroundOpacity / 100.0; // set the desired opacity
temp.Freeze(); // freeze the brush (required)
PanelColorCrossAbove = temp; // assign the temp brush to the brush that will be used later in OnBarUpdate[/CODE]

Thank you Paul. I remember now you already explained this, or something very similar, in a previous post ... apologies for duplicating the question. Best.
