DrawRegion nightmare

[trader2be]

I am using NT 7 build 21 and I cannot get DrawRegion to work correctly. I am getting some weird results, including the opacity of the region changing by itself and some really inconsistent results.
Basically I have two dataseries, each dataseries is defined with maximumbarslookback set to infinite. When Series1 crosses over Series 2 I would like for the area to be blue, and when Series 1 crosses below Series 2 I would like for the area to be red. A new cross over should only change the color of the area looking forward, not the color of the previous regions that were drawn. Can you guys help??
Thanks!

trader2be, can you please share the code you use so we can look into here?

Thanks

This is unfortunately expected : you can't turn a drawn region on / off, you essentially color and recolor the same region then based on your condition for all the bars on the chart (0 to CurrentBar as per your code).

[trader2be]

So, is there a way to change the color of the region based on the conditions that I have specified?

[NinjaTrader_Bertrand]

Please try this code change below -

if (Serie1[0] > Serie2[0]) DrawRegion("DR1" + CurrentBar,1,0,Values[0],Values[1],Color.Transparent,Color.Black,5);
	else DrawRegion("DR2" + CurrentBar,1,0,Values[0],Values[1],Color.Transparent,Color.Yellow,5);
