Problem: Doesn’t fit the books—
$10k a leg is deeper than SunX’s order book right now.
Note: Margin at max leverage$1,000 + $500
HTX 10x, SunX 20x. Keep about 2× this so a sharp move doesn’t liquidate one leg.
OK: Same payment interval4h / 4h
Both legs pay at the same time.
Next 24h at the current rates, on $10k a leg: −$4.28Long HTX: 6 payments, −$7.28; short SunX: 6 payments, +$3.00.
OK: Entry gap works for you−0.114% vs −0.306%
You short the dearer leg. If the gap goes back to average, the short gains.
Watch: Short leg is thinner$2K vs $105K OI
SunX sets your exit cost. Check its book before closing.
