coil_release

// Coil Release: coil strength from symbolic complexity, box-counting fractal dimension and efficiency over len bars; value = setup score 0..1 (coil score times release dynamics); trend context = EMA(ema_len) slope over slope_len bars in ATR units on the chart timeframe (originally a higher timeframe); extra: complexity, fractal_dim, efficiency, chop, coil, coil_score, release_dyn, trend, corr_high, corr_low, was_base; alerts bull/bear_release (first break of the break_len band with the trend) and bull/bear_base_break (break against the trend out of a base; prefix = expected move)
