Observation and evaluation in trading are also very necessary. And I do it whether I'm making a profit or whether I'm making a loss. And yes, sometimes some losses also provide valuable experience as learning that is quite expensive that we can get. As long as we can make appropriate observations and evaluations in responding to it. Without it, don't expect to be able to learn from losses or experiences. Because most of them feel hopeless when they lose, instead of starting to look for loopholes that cause us to experience these losses. Those who can recover from defeat and those who can learn from defeat are those who are one step ahead of others. And I also learned a lot from all of it.
