Together, before fees—needs both histories

The price spread pays, funding is against you. SunX is 0.865% dearer against Injective than usual: you sell high and buy low (spread +0.865% now, against zero (this spread has no 7-day history yet)): +$87 on $10k if it goes back. Holding the pair costs −$1 a day in funding at the current rate, which eats that in about 3 months.
