Both sides work against this trade now: funding costs −$1 a day on $10k at the current rate, and Extended is 0.215% cheaper against BloFin than usual: you would sell low and buy high (−$22 if the spread goes back to its 7-day average of −0.001%). Swap the legs. The two prices were read 74 seconds apart, so part of this spread may be the market moving, not a spread.
