Trading signals for the Aroon Oscillator:


    • Above zero signals an up-trend.
    • Below zero indicates a down-trend.
    • The farther away Aroon Oscillator is from the zero line, the stronger the trend.

A decrease of the Aroon Oscillator from above the 50 line shows that the uptrend is consolidating and is reversing direction downward. When the Aroon Oscillator hovers around the zero line over time, then the market is in a directionless period.
