I don't mean to be a dick, but what exactly are you studying? If you don't have an edge after three years, you probably aren't putting in enough effort or you're not focusing enough on price or you're looking for answers from some external source. If you tell us in more depth what you're doing, perhaps you can get more help and guidance. You said you're studying - what are you studying? You're clearly missing something, and the sooner you can get someone here to help guide you towards what that might be, the sooner you can figure out whether or not you actually have a shot to make it as a trader.
