Close Standard Deviation % (20)Volatility

Timeframe M1 · unit %

What it measures

The population standard deviation of the last 20 closing prices, expressed as a percentage of their mean. A coefficient of variation that normalises dispersion across price levels.

How Janira reads it (bullish vs bearish)

Low values (~0.1-0.3%) indicate tightly clustered closes - the market has been trading in a tight range. High values indicate closes are spread far from their 20-bar average. This metric is purely statistical and carries no directional content.

In plain language

If you lined up the last 20 closing prices on a number line, stddev% measures how spread out they are relative to where they cluster. Small = all huddled together, large = scattered far apart.

Scenarios

• StdDev% < 0.15%: Very low close dispersion. The market is consolidating tightly; energy is compressing.
• StdDev% 0.15%-0.4%: Moderate dispersion, typical of an active session with some directional movement.
• StdDev% > 0.6%: High close dispersion. The market has been making large relative moves across the 20-bar window.
• StdDev% rising after a period of compression: volatility is expanding - the market is moving further from its recent average closes.
