1 ok · 4 to watch
  • Watch: Thin at this size17.6 / 24.5 bp
    At $10k entering HTX costs 24.5 bp, fee and slippage, 1.4× SunX’s.
  • Note: Margin at max leverage$500 + $133
    SunX 20x, HTX 75x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • OK: Same payment interval4h / 4h
    Both legs pay at the same time.
    Next 24h at the current rates, on $10k a leg: +$34.65Long SunX: 6 payments, +$31.65; short HTX: 6 payments, +$3.00.
  • Watch: Gap narrower than usual+0.114% vs +0.228%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Long leg is thinner$496K vs $905K OI
    SunX sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCSunX 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.
