1 ok · 3 to watch
  • Watch: Thin at this size23.8 / 42.3 bp
    At $10k entering Kraken Futures costs 42.3 bp, fee and slippage, 1.8× Aftermath Perps’s.
  • Note: Margin at max leverage$2,000 + $500
    Aftermath Perps 5x, Kraken Futures 20x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
  • OK: Same payment interval1h / 1h
    Both legs pay at the same time.
    Next 24h at the current rates, on $10k a leg: +$31.53Long Aftermath Perps: 24 payments, −$24.15; short Kraken Futures: 24 payments, +$55.68.
  • Note: Gap at its usual level+0.093% vs +0.074%
    The price leg adds little either way.
  • Watch: Long leg is thinner$2K vs $210K OI
    Aftermath Perps sets your exit cost. Check its book before closing.
