Both sides work for this trade now. Funding pays +$8 a day on $10k at the current rate, and GMX is 0.022% dearer against BloFin than usual: you sell high and buy low: +$2 more if the spread goes back to its 7-day average of +0.040%. The two prices were read 189 seconds apart, so part of this spread may be the market moving, not a spread.
