2 ok · 3 to watch
  • Watch: Thin at this size15.1 / 21.0 bp
    At $10k entering BingX costs 21.0 bp, fee and slippage, 1.4× MEXC’s.
  • Note: Margin at max leverage$500 + —
    MEXC 20x, BingX —. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • OK: Same payment interval8h / 8h
    Both legs pay at the same time.
    Next 24h at the current rates, on $10k a leg: −$5.94Long MEXC: 3 payments, −$4.44; short BingX: 3 payments, −$1.50.
  • OK: Entry gap works for you+0.140% vs 0.000%
    You short the dearer leg. If the gap goes back to average, the short gains.
  • Watch: Long leg is thinner$249K vs $998K OI
    MEXC sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
