# Market Structure

> Swings and the HH/HL grammar, BOS/CHoCH, ranges, and Dow foundations.

Market structure is the grammar of swings: higher highs and higher lows, the breaks and character changes that end them, and the ranges in between. Its foundations are Charles Dow’s trend definitions from the 1890s; its modern dialects (BOS, CHoCH, internal versus external structure) power most price-action systems in the Library.
