Trend and Structure

Individual candles are words; structure is the sentence. Strip a chart down to its swing points — each meaningful high, each meaningful low — and a simple grammar appears: an uptrend writes higher highs and higher lows; a downtrend writes lower highs and lower lows; a range writes neither. Every trend definition in the trade, from moving-average slopes to Weinstein's stages, is a formalization of that grammar.

The oldest framework: Dow's three movements

The idea that market movement has structure — layers operating at different scales — is the founding insight of Western technical analysis, from Charles Dow's Wall Street Journal editorials around 1900. Dow died in 1902 without systematizing his thought; his successor William Peter Hamilton did it for him, and because Hamilton's 1922 book is public domain, we can quote the source itself:

The three, in Hamilton's telling: the primary movement — the great bull or bear market, running a year or more; the secondary movement — the sharp reactions against it, the rallies inside bear markets and the corrections inside bull markets; and the daily fluctuation, the surface noise. Hamilton's metaphor for the whole book is in its title: the market as a barometer, registering the combined knowledge and expectations of everyone in it — not a crystal ball, an instrument reading.

Notice this is Module 1's timeframe lesson wearing 1922 clothes: the tide, the waves, the ripples. A trader confused about which movement they're trading is Hamilton's daily fluctuation gambler; a trader aligned with the primary movement is Livermore's Mr. Partridge, murmuring that it's a bull market, you know.

Reading structure in practice

The working method, from the Library's trends and market structure page: mark the swing highs and swing lows on your chosen timeframe, then ask three questions. Are the highs rising or falling? Are the lows rising or falling? And — the question that catches turns — did the most recent swing break the pattern? An uptrend is innocent until a lower low; a downtrend until a higher high. Structure gives you the market's state as a falsifiable statement rather than a mood: "uptrend on the daily until 47.20 breaks" can be checked; "looks bullish" cannot.

Two cautions. Swing selection has judgment in it — zoom in far enough and everything is a swing point; that's why traders anchor structure to one declared timeframe. And structure describes, it doesn't guarantee: trends end, and every higher low is a higher low right up until the one that isn't. Later courses (Dow-theory confirmation, stage analysis, multi-timeframe work) build the machinery for those transitions.

Assignment

Take one daily chart covering about a year. Print it or screenshot it, and mark every meaningful swing high and low by hand. Label the current structure — uptrend, downtrend, or range — and write the falsifiable sentence: "this stays an uptrend unless ___ breaks." Hand-marking structure feels primitive; it's also how the skill becomes permanent.
