When you spot a flawed trade setup right after entering, don't hesitate—exit immediately and take the loss. I've sat through plenty of positions where I jumped in without proper analysis, caught my mistake seconds or minutes later, and cut the position for a small hit. The pattern's always the same: impulsive entries without a solid thesis. Recognizing you're wrong is half the battle; acting on that recognition fast is what separates traders who compound losses from those who live to trade another day. Your ego will want to hold and hope. Ignore it. The best loss is the one you catch early.
