Information about EA’s creation (need Freelance’s answer)

 
I am coming to you because I want to create an EA by a freelancer, but I would like to know how it works if I want to include two indicators that are on TradingView only? How do you act when I say for example "I want the RSI TDI indicator"? Where do I look for the source codes of the chosen indicators?
It's hard to explain, sorry lol
Thank you
