2 ok · 4 to watch
  • OK: Fits both order books7.1 / 14.4 bp
    Entry at $10k a leg, taker fee + slippage. Closing costs about the same.
  • Note: Margin at max leverage$1,000 + $500
    Arcus 10x, MEXC 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: −$1.24Long Arcus: 24 payments, −$1.24; short MEXC: 3 payments, $0.00.
  • Watch: Gap narrower than usual0.000% vs +0.153%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Long leg is thinner$147K vs $854K OI
    Arcus sets your exit cost. Check its book before closing.
  • OK: Points on a legArcus points
    Volume here counts toward the points program.
  • Watch: KYCArcus No · MEXC Yes
    KYC before trading since Feb 2026; unverified accounts see market data only.
