Yes it is possible. With risk management, and the right reading psychology, you can increase your chances of avoiding losses. The exit point is more important than the entry point, which is why you should always keep an active look at the price chart if your trade is for a short term. Adjusting your stop loss is also necessary at times when as per the observation of historical price chart patterns, you know after a certain pattern of downtrend, there is going to be a good uptrend.
Also, many traders do everything right, except their psychology. They will overtrade, enter into trades randomly without a plan, and do revenge trading, losing all their capital. Trading psychology will not only improve your mindset but it will also help you understand the market, and treat forex trading professionally.
