if we understand the market movements, the strategy we use can be dynamic, but it also depends on the existing market conditions, so we can cut losses early, and the most important thing is that we must have a reason for every decision, so that it is not based on mere feeling. Moreover, the smaller the time frame that we use, of course, the more dynamic the strategy used according to the needs of each trader
The fact that many traders have been basing their decisions sometimes on their feelings is what makes them having a bad decision. It's not going to be gone and it could happen anytime to any of us. That's why strategies really are dynamic because they changes overtime, no matter how good you are with your current strategy, you will have that time to replace it when it's necessary. We make mistakes but if you don't learn anything from those, you're wasting your resources.
