Overnight continuation read — top-5 session momentum into the 20:00 UTC signal

Pre-registered overnight continuation read for the Robinhood-tradable crypto universe (81 coins): the top-5 session-momentum coins heading into the 20:00 UTC signal, the BTC 200-day regime gate, the pre/post-signal phase and the cold-study receipts attached to every read — the ranking beat its random null at every fee tier, and at Robinhood retail taker fees the studied trade was REFUTED (breakeven ~19 bps/side). A state read with its refutation attached, not advice; scores and percentages only, never price levels. Refreshed about every 15 minutes around the clock, every day. x402: $0.001 per read in USDC on Base, Solana, or Algorand — the poll-gate tier.

Response

The overnight continuation read: night_board (the 20:00 UTC signal clock, pre/post-signal phase, BTC 200-day gate state, eligible count, the top-5 session-momentum coins, the registered rule prose and the study block — gross edge, null comparison, the retail-fee REFUTATION, breakeven bps) plus universe/eligible counts. Self-dated via computed_at; before the night board's first publish it returns {available:false} with the cadence note. Settlement receipt in the PAYMENT-RESPONSE header.
