Both sides work for this trade now. Funding pays +$31 a day on $10k at the current rate, and BloFin is 0.350% dearer against SunX than usual: you sell high and buy low: +$35 more if the spread goes back to its 7-day average of +0.046%. The two prices were read 55 seconds apart, so part of this spread may be the market moving, not a spread.

The current funding rate is far above what this pair has been paying: over the last 7 days it paid 0.504% in total (about 26.3% a year). A funding rate is set anew for every payment. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
