A trader has a great session. Up 5% on the day. $SOL running.
He is feeling sharp. "I have a good read on the market today." He takes one more trade — a setup that is not quite there, just a feeling.
That last trade gives back half the session's gains.
This is the story of most accounts. Not one big loss. A hundred small bad trades taken when the conditions were not right.
After a good session, the discipline is in stopping. Not in finding one more entry.
The market rewards the disciplined, not the active.
