Percent Above 20-Bar Rolling LowMean reversion

Timeframe M1 · unit %

What it measures

The percentage distance between the current close and the lowest low of the last 20 bars. It measures how far price has rallied from its recent trough, or conversely how close it is to the floor of its recent range.

How Janira reads it (bullish vs bearish)

A value near 0% means price is trading right at or very close to its 20-bar low. A value of +2% means price has recovered 2% from that trough. The higher the reading, the more the recent price action has moved away from the floor. In a mean-reverting context, a very high reading suggests the price has extended upward from its recent base.

In plain language

Think of the 20-bar low as a recent floor. This indicator shows how high above that floor you are currently standing, as a percentage. Being very close to the floor (near 0%) means prices have recently been at a low point and are near the bottom of the short-term range.

Scenarios

Near 0% (below 0.3%): Price is at or just above its 20-bar low. The recent floor is very close - price is near the bottom of its short-term range.
Between 0.3% and 1.5%: Price is a moderate distance above its 20-bar low. It is in the middle zone of the recent range with no pronounced extension signal.
Above 1.5%: Price has extended notably above its 20-bar floor. From a mean-reversion lens, there is a relatively large gap between where price is now and where it recently bottomed.
Above 3%: A significant distance above the 20-bar trough. The floor is now a relatively distant reference; short-term momentum may be the dominant force rather than range reversion.
