For me if you can trade and earn your monthly income over from the forex market then you can leave your work and concentrate on the forex market. Try and trade forex for at least 3 months and see the results and if it is profitable for you then leave your job now !! and you should not leave your current job until you are not entirely sure that you can make enough profit from your forex trading. If you earn enough money from your current full-time job than you can take it as a part-time job to earn extra income.
