I agree that when making a mistake it does not mean we are bad, because mistakes can happen anytime and anywhere and can be considered something natural. But the problem is that some of them misunderstand the natural here and that is not justified, we cannot justify mistakes that continue to repeat themselves, because following the logic at the beginning which considers mistakes to be something natural. We are required to always correct mistakes so that they do not happen in the future.
For example, I know that what we did before made us lose and we conclude it as a mistake. But at the same time we still do it again in the future, clearly that is a stupid thing.
We must remember that trading will be very sensitive because it is directly related to our finances, we must be smart about this.
The truth about trading is that it is not something easy to deal with because it is just a prediction, and some can't be perfect in predictions always. No matter how knowledgeable and experienced someone may be, they will definitely get it wrong sometimes. Nobody is above mistakes; it will surely happen. Sometimes, it's not that someone will make a mistake before they lose, but it can't just happen the way someone may have predicted it despite may have good analysis. It's very clear in trading that sometimes someone's prediction has to be perfect but it won't become trading sometime also work with lucky. However, it's true that as a trader, any mistake that someone to makes lose money should be taken into consideration anytime he or she wants to enter the market, so it can avoid further losses.
Yes, there is no prediction based on analysis that will be perfect, especially what we predict here is something that is very volatile, as we know that the market is volatile. And sometimes there is something that can suddenly change the market conditions, it can come from bad news and good news that exists and affects price movements. I'm not saying that trading depends entirely on luck, but sometimes we also need a little luck so that we can get profit. The luck that is present here is because of our hard work and effort in making analysis of price movements that will occur, and it is based on many factors that can be internal (from within the market itself) or external which usually comes from news about the market.
