Higher Highs and Higher Lows: Uptrend Structure Explained

An uptrend is generally structurally defined by a sequence of higher highs (each subsequent peak in price is higher than the previous peak) and higher lows (each subsequent trough is higher than the previous trough). This structural pattern is what technically confirms an uptrend, beyond a general visual impression of rising price.

Both components are generally considered necessary for a structurally confirmed uptrend. A higher high alone, without a corresponding higher low, might simply reflect a temporary spike rather than a sustained structural uptrend. The combination of both rising peaks and rising troughs reflects a more complete, sustained upward structure.

Each higher low in an uptrend can also be viewed through the lens of the support and resistance concepts covered in the previous unit — each higher low represents a point where buyers stepped in before the previous low was reached, potentially forming minor support zones along the way up.
