Both sides work for this trade now. Funding pays +$5 a day on $10k at the current rate, and Reya is 0.038% dearer against KuCoin than usual: you sell high and buy low: +$4 more if the spread goes back to its 7-day average of −0.035%. The two prices were read 49 seconds apart, so part of this spread may be the market moving, not a spread.
