Before you open

3 ok · 3 to watch
  • Watch: Large against open interest4.5 / 5.4 bp
    $10k is over 10% of Bluefin’s open interest.
  • Note: Margin at max leverage$133 + $250
    TxFlow 75x, Bluefin 40x. 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: +$0.76Long TxFlow: 24 payments, −$2.24; short Bluefin: 24 payments, +$3.00.
  • Watch: Gap narrower than usual+0.028% vs +0.060%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Short leg is thinner$51K vs $23.7M OI
    Bluefin sets your exit cost. Check its book before closing.
  • OK: Points on a legTxFlow points
    Volume here counts toward the points program.
  • OK: No KYC on either legTxFlow No · Bluefin No
