I think this strategy is different for each person. The most common thing is that don't be frustrated easily. Profit or loss in trading can be anything. But if you get frustrated easily, you will make more and more mistakes. In many cases long waits may be required to make a profit. In these cases you have to be patient.
It is a mental state.
But you can't just tell it to someone that don't be frustrated easily because we all have our emotions and it can trigger easily based from our thoughts.
If you're losing the first time, that's tolerable but the 2nd, 3rd and so on. You will really become frustrated about it.
