  • Note: Order book unknown—
    No order-book sample for Extended: its slippage is not counted.
  • Note: Margin at max leverage$1,000 + $500
    Extended 10x, HTX 20x. 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: −$1.20Long Extended: 24 payments, −$1.20; short HTX: 3 payments, $0.00.
  • Note: No 7-day spread history−0.148%
    The gap cannot be compared with its average yet.
  • Watch: Long leg is thinner— vs $5K OI
    Extended sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCExtended 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.
