The price spread pays, funding is against you. Reya is 0.044% dearer against MEXC than usual: you sell high and buy low (spread +0.007% now, against its 7-day average of −0.037%): +$4 on $10k if it goes back. Holding the pair costs −$1 a day in funding at the current rate, which eats that in about 4.0 days. The two prices were read 48 seconds apart, so part of this spread may be the market moving, not a spread.
