Prediction can sometimes favor you or fail you, because trading is also a game of luck and there's no one person that is perfect in prediction, just that when you are favored, it looks like you're the champion but I tell you that no champions forever.
Even those who are professionals and have been trading for years, with the profits earned, cannot avoid losses. But what differentiates them is that those who are more experienced can minimize the risks of the losses they experience.
Losses can happen to anyone. Even though we have made profits in several trades consecutively, we must still be careful and prepare for the next trade as best as we can. Sometimes we take something for granted when we have started getting used to doing it.
