MACD.2 - Check Cloud

 

Hey there, i got a little question to this:

Is is possible to check if the "cloud" turns from red to green and the other way around?

Greetings!

Of course, why not.
 

and could you explain how to do that??

This cloud is coded with some buffers, you have to monitor these values to check when the swap arrives.

I can't be more precise as I don't have the source code.
