2 ok · 4 to watch
  • Watch: Thin at this size25.3 / 10.5 bp
    At $10k entering SunX costs 25.3 bp, fee and slippage, 2.4× TxFlow’s.
  • Note: Margin at max leverage$333 + $200
    SunX 30x, TxFlow 50x. 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: $0.00Long SunX: 3 payments, −$3.00; short TxFlow: 24 payments, +$3.00.
  • Watch: Gap narrower than usual−0.323% vs −0.259%
    Less room for the price leg to pay you. If it goes back to average, the short loses.
  • Watch: Short leg is thinner$13K vs $20K OI
    TxFlow 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 legSunX No · TxFlow No
    Both exchanges let you trade without ID.
