Market state: trending, range, or transition

What it means

Market state is the answer to whether a chart is trending, contained in a range, or doing neither. It is a stronger claim than trend bias because it tests movement as well as direction.

Transition is a real answer here, not a fallback. It means the evidence supports neither reading, and saying so is more useful than picking the closer of two wrong labels.

How we detect it

The engine reads the last forty bars. For a trending state, two independent measures must agree: efficiency — net distance travelled divided by the total path walked — must clear a threshold derived from the window, and the swing labels must show at least a two-to-one majority, with both pointing the same way. Either alone is routinely produced by noise, so either alone is not enough.

For a range, the engine fits a box from the tenth percentile of lows to the ninetieth of highs, so one spike cannot define the edges. Eighty per cent of closes must sit inside it, each edge must have been touched at least twice, and price must still be inside the box today.

That last condition matters more than it looks: a market that has just left its range is in transition, and calling a fresh break range-bound would be the most misleading thing this function could say. When there are fewer than forty bars the answer is insufficient-data, which is not the same as transition.

When the read carries information

• There are enough bars for the window to be full — forty on the timeframe being asked about.
• The instrument's data is continuous and gap-free enough that the path length means something.
• The question being asked is about the recent episode. This is a forty-bar read and does not describe a year.

When it misleads

• A market that trends smoothly inside a wide box can satisfy neither test and read as transition for a long time. That is honest, and it is also unsatisfying.
• Efficiency is a ratio of distances and has no view of time: a trend that took forty bars and one that took four score the same if the shape matches.
• The percentile box ignores anything outside the tenth and ninetieth, so a range that was violently broken twice can still be measured as a range up until the containment test fails.

How it reaches you

This is the read our surfaces use when they describe what a market is doing. Its four possible answers appear as trending up, trending down, range, and transition, with insufficient-data reported plainly rather than hidden behind one of the others.

It describes the recent past. It carries no forecast, and it is never a prompt to act.
