    At $10k entering Binance Spot costs 52.5 bp, fee and slippage, 2.5× Binance’s.
  • Note: Spot in full, margin on the short$10,000 + $200
    The spot leg is bought with the whole $10k; Binance runs at up to 50x. Only the short can be liquidated, when the price rises, while the spot leg's gain is not yet realised: keep about 2× the margin on Binance.
  • OK: Only the short pays funding— / 4h
    The spot leg pays no funding; Binance settles every 4h.
    Next 24h at the current rates, on $10k a leg: +$3.00Long Binance Spot: 0 payments, $0.00; short Binance: 6 payments, +$3.00.

  • Note: No points program—
    Neither exchange runs points right now.
