Technical & Chart AnalysisDirectional Bias
Trend
A sustained directional bias in price, conventionally defined by a sequence of higher highs and higher lows, or the reverse.
What Trend means
A trend is a sustained directional bias in price. The classical definition, inherited from Dow theory, is structural: an uptrend is a sequence of higher swing highs and higher swing lows, a downtrend is lower highs and lower lows, and the absence of either is a range. Trends are usually classified by horizon, with a primary trend running months or years, an intermediate trend weeks, and a short-term trend days or hours. The same market can therefore be trending on the daily chart while ranging on the hourly one.
Traders identify trends with market structure, trendlines, the slope and order of moving averages, or a strength gauge such as ADX. Once a trend is identified, most systems either join it on a pullback or on a fresh breakout in its direction, and use the last swing point as the invalidation level. The limitation is that trends are only ever labelled with certainty in hindsight, and every trend ends. Definitions that require confirmation will always identify a turn some distance after it actually happened.
Worked example
On the daily chart USD/JPY posts successive higher lows at 149.80, 150.90 and 151.60 while making higher highs, so a trader labels the structure an uptrend and treats a close below 151.60 as the first evidence that it has broken.
