1 ok · 4 to watch
  • Watch: Thin at this size200.8 / 26.5 bp
    At $10k entering HTX costs 200.8 bp, fee and slippage, 7.6× SunX’s.
  • Note: Margin at max leverage$133 + $500
    HTX 75x, SunX 20x. 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: −$34.13Long HTX: 6 payments, −$3.00; short SunX: 6 payments, −$31.13.
  • Watch: Gap narrower than usual−0.304% vs −0.227%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Short leg is thinner$497K vs $905K OI
    SunX sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCHTX Limited · SunX No
    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.
