▮ WALLWATCH

Reading it. The split bar is the tug-of-war: green = resting BID mass within 12% plus ask-walls that disappeared; red = resting ASK mass plus bid-walls that disappeared. The white line is the balance point — when it slides left, bears are gaining. The ladder below is the actual battlefield: green bars are bids stacked under price, red bars are asks stacked over it, and the bright row is the current price pushing between them.
⚠ Observation tool, not a tested edge. Measured CTR here is ~27–30 cancels per fill on BOTH sides, so walls vanishing is routine. Four order-book signals were backtested this session; all four were null.
