The previous trade often influences the next one more than the current market does. A win can breed overconfidence and oversized risk, while a loss can trigger revenge trades or hesitant, poorly timed entries.
This emotional carryover turns independent decisions into a chain of reactions that have little to do with actual edge. Professionals treat each setup as a new event with its own probabilities, not as a chance to “make back” or “press” the last result.
Breaking that chain—by pausing, resetting size, and returning to the plan—is frequently more important than refining the setup itself.
