I need an expert advisor

Hello

I would like to know if it is possible to build an expert advisor of the indicator zigzag rnp, with the following characteristics:

Open only 1 operation per section.

To open the operation, just start the new section and close the previous one.

It has the option of opening and closing operations, apart from the automatic form previously described, with the option of SL and TP.

You can indicate working hours. 

That leghs can be modified.

That several pairs can be selected at the same time, without interfering some operations with others.

Even if you turn off the computer, keep running the robot.

Thanks!!!
