Being confident in our abilities is a good thing, but we also have to know so that our confidence does not become excessive confidence, because being overly confident is also not good. We do that to cover up the fears we have. But of course we must not forget to be careful. Emotions must always be in a stable state, because if our emotions are unstable, then when we do an analysis it may not be optimal based on our knowledge and experience. Only we know whether our emotions are stable or not, because it comes from within and we can tell the difference, although it is quite difficult to tell the difference if we are not used to it.
You can be as confident as you want in the correctness of your analysis, but the market can go in the opposite direction and eventually form something else, so the ability to correctly determine what is happening on the market is already half the success. For this, you need to spend too much time with charts and take into account reading them, if there is time and desire for this, then the trader can become successful, and how successful, it will depend on the trader.
Even though we can analyze very well, the market can be unfriendly to us and that makes our previous analysis messy. In a situation like this we need calm, as much as possible do not panic because it will cause us to do something that we should not do. Therefore, our mental readiness in the worst situation is very much needed, because we will not always be in a bad situation, especially this is a trade that we know ourselves how it is in it. The analysis we do will not give us a guarantee that it is what will happen, we still have to stay focused on paying attention to fluctuating market movements. If possible we can make some plans, so that when the first plan does not work we can use the second plan. A strategy like this will be very useful when facing the worst.
