The Aroon indicator is a trend-identification tool that uses two lines — Aroon Up and Aroon Down — to measure how recently the highest high and lowest low occurred within a given period. When Aroon Up is near 100 and Aroon Down is near 0, the security is in a strong uptrend, and vice versa.
This sample displays CSCO daily OHLC data on the main plot and renders the Aroon indicator with period 25 in a separate lower subplot at 30% height. The indicator's range series is styled with custom high stroke (#64b5f6) and low stroke (#ff6d00) colors plus semi-transparent fills. The chart includes dual Y-axes, a synchronized line scroller, a range picker, and a range selector, covering the selected range from November 2002 to November 2007.
