What do coordinates for OBJ_CHANNEL mean?

 

Hello

I'm trying to use an object of type OBJ_CHANNEL in my EA. Can you please tell me what the 3 coordinates are that I must specify? The documentation just says this:

OBJ_CHANNEL: Channel. Uses 3 coordinates.

Well, that's nice but what exactly are the 3 coordinates? Yes I know that each coordinate is a time and a price, but which time and which price? Please explain.

 

You do not must. You can
