I gave up the dream a couple years ago. Day trading just stopped being fun for me . I just got tired of being a break even trader after so many years with the feeling of going nowhere both skills wise and financially. It was also tough to see most of my friends in my social circle develop in their corporate careers and gain a level of financial security, while I was still living as lean as possible in order to maintain my trading account. Part of the reason trading became boring was that I originally got interested in the markets because I enjoyed stock picking and analyzing companies on a fundamental level. Somehow that lead to sitting in front of a monitor alone drawing trend lines on a 5 minute bar chart.
So after about 3 years of trading, I decided to go back to a career in the finance industry. Like a few others have said, the key to addressing your "employment gap due to trading" is to frame it as an advantage, and with the help of some luck it shouldn't be too much of an obstacle. From my experience, most hiring managers don't know much about trading and they will often not be able to understand exactly what you did as a "trader" and won't realize how sad it was that you spent 3 years of your life churning your account in your pjs. That being said, if you want to work at a super competitive job at a hedge fund or an IB, then they will see right through your BS.
