How Long a Trend Usually Lasts

How long a trend lasts is measured from its first turn to its last, and it can only be measured once the last turn is in. This paper measures five real trends of 2024 and 2025 — sixteen to twenty-four weeks each — shows the idea as an hourglass with no markings, puts the longest of the five on the weekly chart, lays all five on one calendar, and shows how to mark a trend's two ends by exact date on your platform.

Five trends, measured

How long a trend lasts is measured from its first turn to its last. Five recent ones, measured that way: the euro's rise of 2025 ran twenty-four weeks and 1,652 pips, a pip being the fourth decimal place, the smallest step most people count in. Gold's rise from December 2024 ran eighteen weeks and 917 dollars. The Nasdaq's rise from April 2025 ran eighteen weeks and 7,644 points. The euro's and the pound's falls of late 2024 ran sixteen weeks each. Five trends, four to six months each. They are five measurements, and the next trend is under no obligation to them.

An hourglass with no markings

The picture is an hourglass with no markings on the glass. While the sand runs you can see how much has fallen — how long the trend has lasted so far — but you cannot read off how much is left, because the glass is not marked. When the sand stops, the whole run can be measured. That is the honest answer to how long a trend lasts: as long as it lasted, known when it has ended, and unknown while it runs.
