Hi People!

Here i have a MA Indicator what change the Linecolor in red, green or yellow.

For using in a other indicator i try to read out the color State of the Line.

I love the smooth behavior of this indicator.

Also the yellow State is a perfect hysteresis for my purposes.

At the bottom of the code you can see how the Color Buffers are working.

But my idea to set a variable "LineColor" and write it to a Global Variable does not work.

When i print the value of "LineColor", the printed value changes every second between 1 (green) and 2 (red), i never see 3 (yellow).

But on screen the colors are always stable.


Have anyone a idea how i can get the stable colorstate of this indicator?


Thanks a lot and best Regards from Germany,

Michael
