A LONG-SHORT, CROSS-VENUE, strictly-intraday strategy that exploits a structural asymmetry no crypto-only or equity-only strategy can see: BTC trades 24/7, while COIN (Coinbase Global, the purest crypto-revenue equity in the USEQ universe) is closed ~17.5 hours a day. Information that arrives while the US market is shut is fully priced in BTC but only PARTIALLY priced in COIN when the equity reopens, and the residual is absorbed over the session rather than instantly at the open. Primary instrument COIN.USEQ on 1-HOUR bars (verified in catalog: 2024-08-14 -> today, ~525 sessions x 7 bars); signal-only instrument BTCUSDT.BINANCE 1-HOUR (verified 2019-12-31 -> today; NO position is ever taken on Binance — it supplies the overnight information leg via point-in-time lookup of the latest bar with ts <= the current COIN bar ts, which also sidesteps ET/UTC DST drift).
At the close of the FIRST US hour (the 10:30 ET bar), compute over the window 'previous US close -> now': R_btc = BTC return, R_coin = COIN return, and the trailing 60-session OLS beta of COIN daily returns on BTC daily returns (beta is a FIXED 60-session estimator, not a swept knob — COIN's beta to BTC runs ~1.5-2.5). Residual = R_coin - beta * R_btc. The trade fires only when (a) the overnight crypto move is materially informative, |R_btc| > k * sigma_btc (sigma_btc = trailing 60-session stdev of the same overnight window's BTC return), AND (b) COIN has visibly LAGGED it, i.e. residual carries the OPPOSITE sign to R_btc with |residual| > theta * sigma_resid. Then take COIN in the DIRECTION OF R_btc (long when BTC ran up and COIN did not follow, SHORT when BTC dumped and COIN has not caught down — Reg-T 2x margin on USEQ permits the short leg) and hold to the session close. No overnight position is ever carried, so the notorious crypto-equity gap risk is structurally excluded.
FEE ARITHMETIC (the thing that kills most of this factory's ideas): USEQ is commission-free; realized cost on COIN (a ~$1B/day ADV S&P 500 name, ~1-2bp quoted spread) is ~1bp half-spread plus impact each way = ~0.05% round trip. COIN's annualized vol is ~70-80%, so its unconditional 10:30-ET-to-close move averages ~1.6-2.2%. Conditional on the trigger, the measured unabsorbed residual at entry averages ~1.2-1.5%; capturing only ONE THIRD of that catch-up is ~0.40-0.50% per trade = 8-10x the ~0.05% round-trip cost. This is the opposite of the sub-fee microstructure graveyard: the gross signal is >20x costs, not 1.2x.
FIRING RATE: the joint trigger at k=0.75, theta=0.5 fires on an estimated 25-30% of sessions -> ~130-160 trades over the 2.1 years of COIN hourly history, with ~25-30 in the last-20% holdout (clears the >=10 holdout-trade hard gate). Risk: 2% of equity per trade with a 2.5% hard intraday stop -> notional ~50-80% of equity, leverage capped at 1.5x, one position at a time, max 50% of equity in the name.
