Constructing the four-input breadth-volume ratio

Four internals can be locked into one advance-decline-volume-ratio with an equilibrium-reading of 1. Editorial: treat the overbought-oversold question as a construction choice about whether the forecast lives on the raw print, a close-based moving-average, or an open-form-average whose hi-lo-index bands tighten toward that balance point.

  • Market-breadth can be built from advancing issues, declining issues, advancing volume, and declining volume rather than from a single issue's close or daily range.
  • The advance-decline-volume-ratio divides the advancing-to-declining issue count by the advancing-to-declining volume ratio, with an equilibrium-reading of 1 labeled bullish between 0 and 1 and bearish above 1.
  • On the raw daily scale, readings above 2.5 and below 0.5 are extreme warnings that can arrive early or keep extending, so they are not automatic reversal confirmations.
  • A moving-average of each day's close, or an open-form-average of the four inputs, makes hi-lo-index extremes rarer and pulls published bands closer to 1.

Four internals instead of one close

A market-breadth construction can be built from four internals: advancing issues, declining issues, advancing volume, and declining volume. That path measures internal participation from many issues at once. It does not start from a single issue's close or daily range.

How the ratio is formed

The advance-decline-volume-ratio divides the advancing-to-declining issue count by the advancing-to-declining volume ratio.

A reading of 1 is defined as the equilibrium-reading. Values between 0 and 1 are labeled bullish. Values above 1 are labeled bearish.

The same four-input ratio can be sampled from minutes to months whenever the four internals are available for that horizon.

Raw prints and extreme warnings

The raw daily series is described as usually remaining between 0.4 and 2.5 and seldom exceeding 4, with one cited 1987 episode above 10.

On the raw scale, readings above 2.5 and below 0.5 are treated as extreme high and low warnings. Those warnings can arrive early or keep extending, so they are not automatic reversal confirmations.

Smoothing the daily close

A common next step is to smooth each day's close with a moving-average. About four to five days is used for short-term work, 20 to 23 days for intermediate work, and 50 to 90 days for a longer outlook.

Lengthening the moving-average makes extreme high and low readings rarer and pulls published guideposts closer to 1. Example bands are 0.7 and 1.25 on a four-day average, 0.85 and 1.10 on a 21-day average, and 0.9 and 1.05 on a 55-day average.

Averaging the inputs first

An open-form-average first averages advancing issues, declining issues, advancing volume, and declining volume over N days, then inserts those averages into the same ratio. That variant is presented as more damping than averaging the finished daily print when conditions are volatile.

High and low bands toward equilibrium

The hi-lo-index is the high and low extremes of the breadth-volume series, raw or smoothed. Those forecast bands become rarer and closer to 1 as the lookback lengthens.
