Card 3: the lull non-trade, 5:30 to 7:30 pm

The third card contains no entry. It is the course's most profitable card for the majority of traders who keep a journal, and that is why it gets a lesson.

Why a card for doing nothing

Module 2 describes the lull: a book losing half its depth, algorithmic flow, divergences that do not pay, 10-point stop runs with no follow-through. Everyone knows it. Almost everyone trades it anyway, because the screen stays on and the morning's reads, which worked, keep producing visually identical signals.

Card 3 turns that knowledge into a written rule, with one precise exception and an exit procedure, because a rule without a written exception ends up bypassed "just this once".
