Order book predicts volatility — not direction (BTC)Bitcoin / TetherUSBINANCE:BTCUSDTAndrey_tradingviewWe study Binance order-book microstructure tick-by-tick (6 pairs, Feb-Jun 2026). A testable, recurring process: when the sell-wall thins out - order-book outflow (resist_minus above the q99 norm) - forward volatility expands x1.4-1.6 over the next 60-300 seconds. A thick wall does the opposite: calm (x0.84-0.94). We deliberately do NOT forecast direction. Forward directional signal measures about 0 by every method we tried - so we trade risk, not a guessed side. This is a logged prediction. We'll publish the validation outcome. We dig, we report, we teach. Research, not financial advice.
