Trend and market structure: highs, lows and moving averages
"The trend is up" is not a feeling. It is a pattern of highs and lows you can check on any chart — and it always describes the past, a few candles late.
- What higher highs, higher lows, lower highs and lower lows are
- Why a swing point is only known a few candles later
- What moving averages add, and why they turn late
Before you start: What a candle is (one bar of a price chart; see "candle" in the glossary).
A trend is a pattern of highs and lows
Price never moves in a straight line. It rises, pulls back, rises again. The turning points are swing points: a swing high where a rise turned down, a swing low where a fall turned up.
Compare each swing with the one before it of the same kind:
- Uptrend — higher highs and higher lows (HH, HL): each rise goes further, each pullback ends higher.
- Downtrend — lower highs and lower lows (LH, LL).
- Neither — the highs and the lows point different ways, or there is no clear sequence at all.
This definition needs no indicator: only the chart.
A swing is known only later
To mark swings by a rule rather than by eye, the terminal uses this one: a candle is a swing high when its high is above the highs of the five candles on each side (and a swing low the same way, with lows). The catch is the right-hand side: you only know a candle was a swing high after five more candles have failed to go above it.
The rule is a choice. On the daily chart below, from 20 September 2025 to 25 January 2026, two candles on each side find 31 swing points, five find 16, and ten find 7. More candles on each side: fewer swings, and later confirmation.
Moving averages: smooth, and late
A moving average replaces each candle's close with an average of recent closes, so the line is calmer than the price. The exponential moving average (EMA) gives the newest closes the most weight: each day's EMA = close × k + yesterday's EMA × (1 − k), with k = 2 ÷ (days + 1). The terminal draws the 20-, 50-, 100- and 200-candle EMAs.
Smoothing has a price: the average turns only after price already has. In the explainer, price closed below the 50-day EMA four days after the top, already 10.6% lower — and on 26 October it closed back above for two days before falling further. In a market that goes sideways, price crosses its averages again and again; between 5 and 20 January 2026 its close crossed the 50-day EMA four times.
- Uptrend: higher highs and higher lows; downtrend: lower highs and lower lows.
- A swing point is confirmed only after the candles that follow it — always late.
- How many swings you see depends on the rule; the terminal uses five candles on each side.
- Moving averages smooth price and turn late; sideways markets cross them again and again.
- Structure describes the past, not the next move.
