Just a note on position reference: Since it's called a reference, you need to use your brain to think about whether a position can be taken. You are responsible for your own profits and losses, don't complain and make excuses, whether you want to read it or not is up to you. First of all, I provide data references free of charge, I'm not here to play you for suckers. If someone charges you and leads you to make wrong decisions or incur losses, feel free to criticize and expose them.
