The price spread pays, funding is against you. Aster is 0.028% dearer against GMX than usual: you sell high and buy low (spread −0.011% now, against its 7-day average of −0.039%): +$3 on $10k if it goes back. Holding the pair costs −$6 a day in funding at the current rate, which eats that in about 12 hours. At the pace of the last 3 days (−0.087% in total) that is about 25 hours.
