Most automated chart pattern detectors validate geometry but ignore context. Reversal shapes inside ranges and continuation shapes without a prior impulse are routinely misclassified when prerequisite structure is not enforced.
A second failure mode is timeframe coupling. Swing logic computed on the same chart timeframe inherits intraday noise, causing trend state to flip repeatedly and invalidating context checks.
A proposed MQL5 approach fixes both issues by reading market structure from H4 regardless of the trading timeframe. H4 swing points are detected with a configurable strength window, labeled HH/LH/HL/LL, and the latest labels define trend state. Patterns on lower timeframes are evaluated only when the H4 prerequisite is met, while drawing remains correct via datetime anchoring.
