If you have traded for a long time and don't know whether to continue trading or no, the best decision would be "to continue".
 For this time, you have gotten a lot of your own experience and in the future, you can use your skills all out. Your last fails may become your strong points you can use in your further trading. Maybe, if you failed in the past, you need to change your trading strategy and use new trading methods to reach more success. About new trading strategies and methods, you can get to know on the Newconsort platform which I already use.
