0 ok · 5 to watch
  • Watch: Thin at this size34.7 / 59.8 bp
    At $10k entering Popdex costs 59.8 bp, fee and slippage, 1.7× MEXC’s.
  • Note: Margin at max leverage$500 + $500
    MEXC 20x, Popdex 20x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • Watch: Payment intervals differ8h / 1h
    Payments land at different times. Close right after the slower leg pays.
    Next 24h at the current rates, on $10k a leg: −$20.40Long MEXC: 3 payments, $0.00; short Popdex: 24 payments, −$20.40.
  • Watch: Gap narrower than usual−1.127% vs −0.022%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Short leg is thinner$319K vs $889K OI
    Popdex sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCMEXC Yes · Popdex No
