The Rate of Change (ROC) is a momentum oscillator that measures the percentage change in price between the current value and a value a specified number of periods ago. Positive ROC values indicate upward price momentum, while negative values signal downward momentum, making it useful for detecting divergences and confirming trend direction.
This sample displays CSCO daily OHLC data on the main plot and renders the ROC indicator with period 12 in a 30% height subplot, styled with a blue (#64b5f6) stroke. The chart features dual Y-axes on both plots, a synchronized line scroller, a range picker, and a range selector.
See the Technical Indicators documentation for all configuration options.
