It is indeed common, in fact every trader has experienced it, the only difference is how they can control their emotions, so they can comply with the rules they have made themselves. It is difficult for us without practice to control our emotions. By practicing more, we will have experience and that way we will be able to form our own emotional stability, but remember we also have to be disciplined towards ourselves.
At the beginning when a newbie enters into the trading field then everything seems different from what they have learned so it is obvious that handling their emotions after the first loss will be more difficult for them but when they trade again and again so they will get experience.
Due to increased experience they will enhance their profit so after huge gain if they face a single loss then they will be able to tolerate this as they will have experience that after each loss they will surely take profit if they are experts traders.
