The price spread pays, funding is against you. OKX is 0.538% dearer against Extended than usual: you sell high and buy low (spread +0.538% now, against zero (this spread has no 7-day history yet)): +$54 on $10k if it goes back. Holding the pair costs −$1 a day in funding at the current rate, which eats that in about 45 days.
