Orders for forex consultation - Statistics and mathematics - new

Hello I am new to MT4/MT5, I previously traded for a company with their own internal execution platform. I am looking for someone who can help me understand MT5, how to set up charts, indicators, advisors and back-testing etc.. basically a intro to a new user. I am particularly interested in learning is it possible to trade/execute spreads via MT5 - ie simultaneously buy MSFT and sell DELL, and when you trade out you

I want to lock my indicators and my EAs in the data folder with a password because i am going to give my pc to a trader , the real names of the indicators also should be changed or covered on the screen so no one should go and find them online
