Help me to re-Code multiple EAs into One

I am new in programming, I just understand the basic. It is my first EA based on custom indicator, so I use iCustom function.

Please help me to re-Code my EA become a single EA (without using iCustom function), so I wasn't need to attach the custom indicator if I wanna using it in another terminal /computer.

Raitis AW Tes is my EA and another was the custom indicator that I used. Thanks
