This ranks momentum against bands that mark where the market has been unusually stretched before, and it does so on slow closes rather than daily ones. That choice is what makes it a cycle instrument instead of a trading one.

The bands are not thresholds to act on. Time spent in the upper band has preceded cooling and long stretches in the lower one have framed the periods people later describe as accumulation, and neither of those is a moment.

What it actually measures

What is shown by default is a rank against this market’s own past rather than the bare figure. A bare oscillator number carries no meaning until you know whether it is unusual here, and the rank is what supplies that.

Two speeds answer different questions on the same asset. The faster basis surfaces swing-scale stretch and the slower one isolates the multi-month kind, and they routinely disagree.

The markers put past extremes back onto the price line. Seeing where previous stretched readings actually landed is the quickest way to judge whether they have ever mattered on this particular market.

Stretched is a description, not an instruction

An oscillator sitting in its upper band feels like a decision. It says the market is far from its own centre, which sounds like a reason to do something about it.

A strong trend will hold an extreme for months, and each of those months produces an identical reading. What the extreme records is distance already covered, never distance remaining, and conflating the two is the standard route to being early and wrong.

Ratio Vector: a high reading is health until it is not

A high reading is a strength reading before it is anything else. The near-term trend leading its slower reference is what an advance in good health looks like, and it turns into a caution only at the far end of the range.

Most stretch measures are framed as warnings, so a high reading is read as a problem. On this one the ordinary meaning of a high reading is that the trend is working.

The transition from strength to overextension is not a line, and nothing on the chart marks the crossing. What the reading gives is the position on a continuum, and the judgement about where that position becomes uncomfortable stays with the reader.

What it does not tell you

Slow closes mean slow confirmation. The same choice that keeps day-to-day noise out of the reading also means it has nothing to say about this week, and it is not intended to.

The rank depends on the history available. A market with a short record has fewer past extremes to be ranked against, and its percentiles are correspondingly less meaningful.

Bands are a convention rather than a discovery. Where the lines are drawn is a judgement about what counts as unusual here, and a different defensible judgement would relabel a good deal of the same history.

How to read it

Overbought. Stretched against its own recent range, which is a late-trend condition.

Neutral. The unremarkable middle, where the reading supplies background instead of urgency.

Oversold. Deeply washed out. Long stretches here have framed accumulation rather than marked a floor.

Common questions

Why two speeds?

Because they answer different questions on the same market. The faster one surfaces swing-scale stretch and the slower one isolates the multi-month kind, and their disagreement is often the useful part.

Why show a rank rather than the value?

Because a bare oscillator number carries no meaning until you know whether it is unusual on this particular market. Placing it against the market’s own past is what supplies the missing half.

Does the upper band mean sell?

No. Time spent there has preceded cooling, and a strong trend can hold the same reading for months. It gauges stretch and does not generate a moment.

What do the markers on price show?

The days when the reading sat in an extreme, drawn back onto the price line. It is the fastest way to check whether past extremes actually mattered on this market.

Why keep this alongside the faster oscillator?

Because they work on different clocks. This one runs on slow closes and describes stretch at cycle scale; the fast one travels edge to edge many times inside a single reading here.

What is being compared?

The recent trend against a slower reference, reported on a fixed scale so that readings are comparable across markets and periods rather than being coloured by each one’s volatility.

Which display should be used?

The raw reading against set thresholds answers a question about this market alone; the ranked version puts the same reading against the market’s own record, which is what lets two markets be compared.
