Before you open

1 ok · 5 to watch
  • Watch: Large against open interest3.1 / 8.9 bp
    $10k is over 10% of TxFlow’s open interest.
  • Note: Margin at max leverage$33 + $200
    MEXC 300x, 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: +$5.31Long MEXC: 3 payments, +$2.31; short TxFlow: 24 payments, +$3.00.
  • Watch: Prices read 48 s apart−0.080% vs −0.176%
    Part of this gap may be the market moving.
  • Watch: Short leg is thinner$23K vs $6.3M OI
    TxFlow sets your exit cost. Check its book before closing.
  • OK: Points on a legTxFlow points
    Volume here counts toward the points program.
  • Watch: KYCMEXC Yes · TxFlow No

10-14 12:02PhemexOther$OP got the first move. Now comes the harder part. Is capital rotating back into L2s, or is this a sharp bounce from beaten-down levels? Price is the headline. Follow-through is the test. Which side are you watching?👇 @Phemex_official on X ↗
