The plan at 4:16 pm, the 7,681 trap and the lessons

At 4:16 pm, both positions are closed, price is at 7,641.50 in a short gamma regime, and nearly five hours of session remain. A trader who stops there has done their day; a trader who carries on rewrites their if/then plan before looking at the book. This lesson gives that plan, then the most debated trap of the session, then five lessons that go beyond this one day.

The situation at 4:16 pm and the if/then plan

Price is fifteen points below Zero Gamma, on a small negative strike. The 0DTE effect will grow late in the session, and it is the last session of the month.
