Aroon Oscillator (AROONOSC)

AROONOSC is the difference between Aroon Up and Aroon Down: AROONOSC = AroonUp - AroonDown. This creates a single oscillator ranging from -100 to +100. Positive values indicate bullish momentum (recent highs more recent than recent lows), negative values indicate bearish momentum. Zero-line crosses signal trend transitions. AROONOSC simplifies Aroon's dual-line interpretation into one momentum measure, making trend direction immediately apparent from sign and magnitude.

Cryptocurrency traders use AROONOSC for simplified trend identification - positive values confirm uptrends, negative confirm downtrends. Crosses above zero generate buy signals (uptrend emerging), crosses below zero generate sell signals (downtrend emerging). Values near +100 or -100 indicate very strong trends. The zero line acts as a key decision level separating bull and bear regimes. AROONOSC works particularly well for identifying trend continuation versus consolidation. Combine with volume for momentum confirmation, with ADX for trend strength, or with moving averages for directional alignment. Day traders and swing traders favor AROONOSC for clear trend signals.
