Current-bar versus prior-bar range construction for the stochastic oscillator

The stochastic oscillator locates the close inside a high-low envelope, then forms a raw ratio, a short summed quick line, and a short averaged slow line. A one-bar displacement decides whether that envelope includes the current bar, which changes what the oscillator can show on a breakout.

  • The stochastic construction locates the close inside a high-low envelope of stated length, then forms a raw ratio, a short summed quick line, and a short averaged slow line.
  • A displacement of zero includes the current bar in the envelope, while a displacement of one uses the prior-bar high and low so the same construction can be compared side by side.
  • The price-band oscillator is the same close-to-low percentage of the band width, plotted without the extra stochastic smoothing steps.
  • Including the current day in the range is presented as limiting how freely the oscillator can move when a breakout occurs.

How the oscillator is assembled

The stochastic oscillator is a bounded oscillator that locates the close inside a lookback high-low envelope and may then smooth that location over a short window. The construction first places the close inside an envelope of stated length, then forms a raw ratio, a short summed quick line, and a short averaged slow line.

The raw channel is the unsmoothed close-to-range ratio taken from the current-bar high-low envelope. The quick line is a short summation of close-to-low distances divided by the matching summation of range widths. The slow line is a short moving average of the quick line.

The supplied implementations use a 14-bar lookback and 3-bar summation or averaging windows, with a zero-range guard so the ratio is computed only when the envelope has width.

Displacement and the price band

A displacement input of zero includes the current bar in the envelope. A displacement of one uses the prior-bar high and low so the same formulas can be compared side by side.

The price band is the highest high and lowest low over a stated lookback, optionally taken from the prior bar rather than the current bar. The price-band oscillator is the same close-to-low percentage of the band width, plotted without the extra stochastic smoothing steps.

Reference lines at 0 and 100 mark when the close sits at the bottom or top of the constructed range.

Why the one-bar shift matters on a breakout

Side-by-side comparison is the point of the displacement input. With displacement at zero, the current bar belongs to the range. With displacement at one, the envelope is the prior-bar high and low, and the close is still measured against that older band.

TradersWeek editorial reading: the shift does not change the close-to-low percentage itself. It changes which bars define the band edges, and that is what the oscillator can show when price leaves the prior range.

McKesson prior-bar price-band oscillator

A 14-session high-low envelope taken from the prior bar leaves room for McKesson to close outside that envelope. The oscillator therefore drops through zero on the September break and finishes at the labeled 104.62 on the November bounce. Weekly readings were taken from the eSignal oscillator pane; only that final 104.62 is a printed value.
