Both sides work for this trade now. Funding pays +$2 a day on $10k at the current rate, and SunX is 0.032% dearer against Reya than usual: you sell high and buy low: +$3 more if the spread goes back to its 7-day average of +0.007%. The two prices were read 50 seconds apart, so part of this spread may be the market moving, not a spread.
