Rate of Change (ROC-12)Momentum

Timeframe M1 · unit %

What it measures

ROC-12 measures the percentage change in close price from 12 bars ago to now. It directly quantifies velocity: how fast the market moved over the last 12 minutes.

How Janira reads it (bullish vs bearish)

A reading of +2 means price is 2% higher than 12 bars ago. A reading of −1.5 means price has fallen 1.5% in the same span. Zero means price is exactly unchanged over 12 bars. Extreme readings (±3%+) indicate unusually fast moves.

In plain language

ROC is the simplest momentum measure: it just compares where you are now with where you were 12 bars ago and tells you the percentage difference. Positive = you climbed, negative = you fell, zero = you're back where you started.

Scenarios

Consistently positive over several bars: price has been rising steadily for at least 12 minutes - trend momentum is present.
ROC near zero after a large move: price has stalled - the velocity of the earlier move has dissipated and the market is consolidating.
Large negative reading: a rapid decline of price from 12 bars ago - the market has lost significant ground quickly.
ROC diverges from price (new high but lower ROC): the latest price peak was reached at slower speed than the previous one - the pace of the move is decelerating even as price makes a new high.
