  • Note: Order book unknown—
    No order-book sample for Reya: its slippage is not counted.
  • Note: Margin at max leverage$1,250 + $333
    Reya 8x, HTX 30x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • Watch: Payment intervals differ1h / 8h
    Payments land at different times. Close right after the slower leg pays.
    Next 24h at the current rates, on $10k a leg: −$3.00Long Reya: 24 payments, −$3.00; short HTX: 3 payments, $0.00.
  • OK: Entry gap works for you+0.237% vs +0.210%
    You short the dearer leg. If the gap goes back to average, the short gains.
  • Watch: Long leg is thinner$37K vs $108K OI
    Reya sets your exit cost. Check its book before closing.
  • OK: Points on a legReya points
    Volume here counts toward the points program.
  • Watch: KYCReya No · HTX Limited
    No ID for accounts opened since 2026-03-30: futures up to 5x and no API trading; more leverage and the API need level-2 KYC.
