Both sides work against this trade now: funding costs −$7 a day on $10k at the current rate, and SunX is 0.149% cheaper against BloFin than usual: you would sell low and buy high (−$15 if the spread goes back to its 7-day average of −0.199%). Swap the legs. Mind the row above: over the last 7 days funding on this pair paid +0.088%, so the current rate has only just turned against you. 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 0.088% in total (about 4.6% a year). A funding rate is set anew for every payment; at this rate the next one is about −$1.24 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
