Freedom from deadline-driven profit
"I must reach this target within ten days." "I need this many dollars this month." Pressure of this kind pulls a trader out of his system: need begins to take the decisions that setups should take, and emotion displaces discipline. The market owes no one an opportunity on a schedule. When none appears, waiting is part of the work.
﴿وَمَا تَدْرِي نَفْسٌ مَاذَا تَكْسِبُ غَدًا﴾No soul knows what it will earn tomorrow.
Not "I must make a profit today", but "today I must follow my trading rules faithfully."
