Please, how can I program my EA to return the values of extern or input variables from other charts? It is not as if I want to attach several EA's to charts. What function is necessary to achieve such a task? In view of my question, exactly what do the following mean for variable of extern?
If you have no EA attatched to the other charts, do you think extern or input variables are generated out of thin air?
Or are this variables part of a script or indicator?
