Zone-check rule

Rule version v1, effective 5 October 2026. A zone is HELD if no 15-minute candle closes beyond its far edge during the session; BROKE if one does; NOT TESTED if price never entered it. Far edge: the top of a resistance zone, the bottom of a support zone. Any change to the rule is announced with a date and a new version number.

Illustrative and hypothetical items

Explainers (zone check, the wall, theta) and the sample charts that appear before live data starts use made-up numbers. They carry an ILLUSTRATIVE or HYPOTHETICAL badge. Calculators show hypothetical results from the numbers you type. Past results do not predict future results. Derivatives carry a high risk of loss.
