# Aroon Oscillator

Strategy guide

### Overview

The Aroon Oscillator is a trend-following indicator that uses aspects of the Aroon Indicator (Aroon Up and Aroon Down) to gauge the strength of a current trend and the likelihood that it will continue. It is calculated by subtracting Aroon down from Aroon up. A buy signal is produced when the Aroon Oscillator crosses above zero. A sell signal is produced when the indicator crosses below zero.
