 The Aroon Oscillator condenses the dual-line Aroon system into a single zero-centered value by computing $\text{AroonUp} - \text{AroonDown}$. This distills the temporal battle between fresh highs and fresh lows into a bounded $[-100, +100]$ metric where positive values indicate bullish recency dominance and negative values indicate bearish. Unlike recursive indicators that accumulate floating-point drift, the Aroon Oscillator is purely windowed — its value depends only on data within the lookback period, making it stateless in the long term and immune to initialization poisoning. The step-function output reflects discrete events (new extremes appearing or aging out) rather than smooth price trajectories.
