Wrong Brush Used for Background in Fast Moving Market

[GoldBands]

I have an indicator the paints the background color based on various conditions. Normally, everything works fine and the correct background color is painted. However, when the market is moving fast (I am using volume bars), the prior background color is used even though conditions have changed and a new color should be used. The strange thing is that if I press F5 to reload the script, then the correct color is used. And as I said, if the market is moving at a 'normal' pace, the correct color is also used.

Here's my code:

if(Close[0] > emaMid[0] && Close[0] > emaSlow[0]) {



Brush myBrush = new SolidColorBrush(Color.FromArgb(faOpacity, faRed, faGreen, faBlue));

myBrush.Freeze();

BackBrush = myBrush;

}

else if(Close[0] < emaMid[0] && Close[0] < emaSlow[0]){

Brush myBrush = new SolidColorBrush(Color.FromArgb(fbOpacity, fbRed, fbGreen, fbBlue));

myBrush.Freeze();

BackBrush = myBrush;

}

else{

BackBrush = null;

AboveBelow[0] = 0;

}

Any idea why this is happening?

Thanks.

Hello GoldBands,

If you declare a variable in the scope of an if's action block, it can only be used in that action block.

If you want to be able to set the variable and use this throughout the script, declare the variable of the scope of the class, and assign the value in State.DataLoaded.

In the class:
private Brush myBrush;

In OnStateChange when State is State.DataLoaded:
myBrush = new SolidColorBrush(Color.FromArgb(fbOpacity, fbRed, fbGreen, fbBlue));
myBrush.Freeze();

In OnBarUpdate():
BackBrush = myBrush;

Great. That fixed the issue. Thanks!
