The price spread pays, funding is against you. Aster is 0.062% dearer against Reya than usual: you sell high and buy low (spread +0.062% now, against zero (this spread has no 7-day history yet)): +$6 on $10k if it goes back. Holding the pair costs −$10 a day in funding at the current rate, which eats that in about 15 hours.
