BulgeShift
Mass Index Expansion Gate + Balance of Power Zero Cross
Core Idea
BulgeShift watches for the classic "range balloons, then deflates" fingerprint that often precedes a directional shift. A Mass Index gauge tracks how puffed-up each candle's high-low range has become relative to its own trailing 100-bar history; when that reading ranks in the top 40% (≥60th percentile), the "expansion zone" is open. Inside that window, a smoothed Balance of Power (BOP) line — which measures whether bulls or bears closed each candle more forcefully — is watched for a cross of its own zero line. That cross, confirmed by a minimum volatility gate, is the trade trigger.
