The price spread pays, funding is against you. Arcus is 0.507% dearer against BloFin than usual: you sell high and buy low (spread +0.514% now, against its 7-day average of +0.008%): +$51 on $10k if it goes back. Holding the pair costs −$22 a day in funding at the current rate, which eats that in about 2.3 days. Mind the row above: over the last 4 days funding on this pair paid +0.266%, so the current rate has only just turned against you. The two prices were read 95 seconds apart, so part of this spread may be the market moving, not a spread.
