The Rank Correlation Index (RCI) measures the correlation between time ranks and price ranks over a given period. Values near +1 signal a strong uptrend, values near -1 indicate a strong downtrend, and values near zero suggest no clear trend — making RCI useful for identifying trend strength and potential reversals.
This sample renders T (AT&T) daily OHLC data on the main plot with volume columns overlaid at 25% max height using a logarithmic Y-scale and custom rising (red) and falling (green) colors. The RCI indicator is displayed in a 30% height lower subplot with a blue (#1f73b4) 2px stroke. The chart includes an area scroller, a range picker, and a range selector, covering January 2000 to January 2019.
