0 ok · 5 to watch
  • Watch: Large against open interest3.6 / 11.0 bp
    $10k is over 10% of Aftermath Perps’s open interest.
  • Note: Margin at max leverage$50 + $1,000
    MEXC 200x, Aftermath Perps 10x. 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: +$26.57Long MEXC: 3 payments, $0.00; short Aftermath Perps: 24 payments, +$26.57.
  • Watch: Gap narrower than usual−0.390% vs −0.166%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Short leg is thinner$9K vs $58.2M OI
    Aftermath Perps sets your exit cost. Check its book before closing.
  • Note: No points program—
    Neither exchange runs points right now.
  • Watch: KYCMEXC Yes · Aftermath Perps No
    KYC before trading since Feb 2026; unverified accounts see market data only.
