Determine current color of indicator line?
Here is the source code of v1.0 which sadly redraws in history, the version 1.2 attached in the above post does not do that, thats why I would have liked to use it.
Maybe the code of v1.0 is enough to figure out how to detect the different colors.

You don't need to know the colour. You need to check the buffers' values. if != EMPTY_VALUE, then you know that that buffer line is visible.
But you also need to take into account that for a line to show, the previous buffer also usually != EMPTY_VALUE.

Thank you for your answer!
I know, the line is always shown. My problem is that i need to know the color.
Looking at the value it provides didn't really helped me, any suggestions ? In some cases all got values in it.
You cannot get the colour, the colour is irrelevant as it can be inputted as a different colour in the indicator inputs.
If you compare adjacent bars and the buffer has a value for both, then you know that that buffer draws a line between those 2 bars.
The problem comes when some indicators more than 1 buffer draws a line between the same 2 bars, then only 1 colour shows.
A good way to check is to put the indicator on a chart and set the colour for all drawn buffers except 1 to no colour. Then only 1 colour will show in sections. The buffer that always has a value for the bars where the line shows is the buffer that you are interested in for that particular colour.

If it does not, then it is using simple LWMA and has nothing in common with centered TMA (or TMA)

Hello,
I am using the indicator "TMAcentered MACD v1.2.ex4 " and I want to include it into my EA. But right now I got a problem, how can I determine the current color of it programmatically ?
