leg_character

// Leg Character: character of the live leg from the last alternating pivot (min_leg_atr filter) to the current extreme, from ten features (efficiency, overlap, retracement, commitment, wick cleanliness, momentum/true-range expansion, EMA support, cleanliness, acceptance); value = impulse score 0..100 (correction = 100 - impulse, both pulled to 50 by maturity); extra: correction, confidence, maturity, bars, direction, class, leg_start, the ten features, internal_swings, avg_internal_swing_atr, progression_ratio, sub_leg_growth; state impulse/correction/neutral with hysteresis; alerts bull/bear_impulse (leg direction), correction_started, character_lost
