Trend Strength

What it measures

Trend Strength (ADX) measures how strong a trend is, not its direction: is there a clear path at all, or just sideways chop? Below 20 the market has no trend worth counting. Above 25 a trend is in place, and the higher the number, the more it can be trusted, up or down.

Why it decides which tools to use

Strategies come in two opposite families. Trend tools (breakouts, riding the move, trailing stops) do well when clarity is high and get chopped up in choppy markets by false signals. Range tools (mean reversion, selling the edges) live on choppiness and get run over in trends. This indicator tells you which family fits the current season.

Reading its curves

A rise from a low base is a sign of a new trend being born, and it matters more than the absolute value. A turn down from a high peak says the old trend is losing strength even if price has not reversed yet.

Hypothetical example

A stock swings sideways for two months and its trend indicator sleeps at 14. Then it breaks the range and the indicator climbs to 32 within two weeks. The break is not a whim. A trend was born, and trend-riding tools are now the fit.

Common mistake

Reading it as a rising-trend indicator: its value goes up in sharp crashes just as it does in strong rallies. It is a clarity gauge that takes no side. Direction is read from price and its components.

How to read it in a decision

Trend strength is a measure of confidence, not direction. A clear trend justifies a larger size for the same idea, and a murky one calls for a smaller size however convincing the view looks. It sets the dose before it sets the direction.

Where to see it on the platform

Quantitative analysis tools show it among the trend measures, and the strategy picker in the calculator uses the same logic (trend or range) to suggest a suitable family.

Analysis panels show it with its components, so you can see which layer built the clarity and which one is out of tune.
