/**
 * Adaptive MACD [LuxAlgo]
 *
 * R-squared correlation-based adaptive MACD.
 * The MACD line adapts its speed based on the Pearson correlation between
 * price and bar index (R²). When price is trending (high R²), MACD behaves
 * like standard MACD. When choppy (low R²), the adaptive factor K changes
 * the lag characteristics.
 *
 * Formula:
 *   a1 = 2/(fast+1), a2 = 2/(slow+1)
 *   r2 = 0.5 * correlation(close, bar_index, length)^2 + 0.5
 *   K = r2 * (1-a1)(1-a2) + (1-r2) * (1-a1)/(1-a2)
 *   macd[i] = (close - close[1]) * (a1-a2) + (2-a1-a2) * macd[1] - K * macd[2]
 *   signal = EMA(macd, signalLen)
 *   histogram = macd - signal
