‘Salary’ will be determined by your account balance, risk tolerance, and how long you want to be in the game.
I regularly see high-risk forex traders make 500-1,000%+ in less than a year, then blow their accounts the following year.
I also see low-risk stock traders that consistently make about 20-40% per year, year after year.
Are you looking to grow wealth over the long term or to have a regular second income? Your trading strategy will depend on this outlook.
