ROC
How much the close has changed over the lookback, in four scales.
ROC (rate of change) compares the close with the close a chosen number of bars back. It is its own pane under the candles.
Default length is 9. The scale is percent: 1 means the close is 1% higher than it was. The other scales are the same comparison as a fraction, as a ratio (1 means unchanged), or as that ratio times 100.
Above the unchanged value the close is higher than it was; below it, lower. Crossing that value is a common read, not a signal by itself.
Settings: gear on the pane bar — see Indicators.
