Percent Below 20-Bar Rolling HighMean reversion

Timeframe M1 · unit %

What it measures

The percentage gap between the current close and the highest high reached in the last 20 bars. It measures how far price has pulled back from its recent peak, or conversely how close it is to the top of its recent range.

How Janira reads it (bullish vs bearish)

A value near 0% means the price is trading very close to or at its 20-bar high. A value of -2% means price has retreated 2% from that peak. The more negative the reading, the deeper the pullback from the recent ceiling. In a mean-reverting context, prices very near the 20-bar high have recently stretched upward; prices far below suggest the high may act as a gravitational reference for future upside.

In plain language

Think of the 20-bar high as a recent ceiling. This indicator shows what floor you are currently standing on relative to that ceiling - expressed as a percentage drop from it. Standing very close to the ceiling (near 0%) means the price has just been at a high point.

Scenarios

Near 0% (above -0.3%): Price is at or very near its 20-bar peak. The recent upward stretch is intact - buyers have not let it fall far from the high.
Between -0.3% and -1.5%: A moderate pullback from the 20-bar high. Price is in the middle zone of its recent range, with no strong mean-reversion signal either way.
Below -1.5%: A notable retreat from the recent high. The larger the negative value, the more room price has theoretically 'opened up' back toward the high.
Below -3%: Significant distance from the 20-bar peak. The high is now a relatively distant reference; other reversion anchors (VWAP, SMA) may be more relevant in the short term.
