Problem: Doesn’t fit the books—
$10k a leg is deeper than SunX’s order book right now.
Note: Margin at max leverage$500 + $1,000
SunX 20x, HTX 10x. 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: +$1.14Long SunX: 6 payments, −$3.00; short HTX: 6 payments, +$4.14.
OK: Entry gap works for you+0.743% vs +0.312%
You short the dearer leg. If the gap goes back to average, the short gains.
Watch: Long leg is thinner$2K vs $105K OI
SunX sets your exit cost. Check its book before closing.

No ID for accounts opened since 2026-03-30: futures up to 5x and no API trading; more leverage and the API need level-2 KYC.
