A loss in trading is not a loss.
Here is why;
Most traders take losses and get frustrated why their trading strategy is not working.
However, because of their myopic mindset or weak psychology, they forget to understand that a loss is only a learning process or lesson for trading.
Each loss will not only help you but it will mould the successful trader you will tend to become in future.
It may hard now, but in years, you will be shock at yourself because both the pre-mature and mature traders will be under your tutelage for more knowledge(learning of tips and strategy) and they will be equally recognize you as their MASTER in trading space.
Of course, when trading losses we need to think positively and even have to think optimistically while learning from mistakes and continuing to learn. Because successful trading can make experience a teacher and loss is part of trading. Indeed, sometimes, those who look the most optimistic and think positively are those who are the most fragile and vulnerable to negative thoughts. However, if we continue to practice every time a loss occurs, we can definitely be better at trading.
The point is if something happens in trading, say "this too shall pass" to remind yourself that all bad situations in trading are risks to learn better, so this is only temporary. Stay calm, face it wisely, and believe that time will bring changes in your trading but still accompanied by knowledge. That's when you need to train your mind to focus more on positive things and train your brain to stay positive and optimistic. Trading becomes more relaxed and less stressful, if you realize that you don't need to catch every market movement.
