Funding, last 3 days (all we have)—no history yet

Price spread, last 7 days—no price history on both exchanges yet

Together, before fees—needs both histories

Both sides work against this trade now: funding costs −$3 a day on $10k at the current rate, and GMX is 0.153% cheaper against OKX than usual: you would sell low and buy high (−$15 if the spread goes back to zero (this spread has no 7-day history yet)). Swap the legs.
