This should answer all your questions in regards to using TradingView with AMP. https://faq.ampfutures.com/hc/en-us/sections/204505528-TradingView
Correction, apparently you do NOT need a TradingView subscription to connect to a broker, you so have to buy the CQG data through AMP. If you plan on trading indices like ES and NQ only you don't need the bundle, you need the CME/Globex data which is $13 for level 2 and $3 for level 1.
No offense, you need to go back and refresh your high school arithmetics before you start trading. 100% a year compound for three years is 8. If you start with $1K, at the end or year 3 you will have $8K. You can't retire with that. At a minimum you need $125K to start so at the end of year 3 you have $1M Canadian. You sounded like a twenty something and if you already have $125 K saved, you won't be looking to get rich quick trading futures.
No one is stopping you considering so many from all over the world simply cross the boarder. It is much easier coming down from the North instead of coming up from the south. Even Trump is not complaining about people coming from the north.
