Both sides work against this trade now: funding costs −$7 a day on $10k at the current rate, and MEXC is 0.178% cheaper against SunX than usual: you would sell low and buy high (−$18 if the spread goes back to its 7-day average of −0.016%). Swap the legs. The two prices were read 53 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 -0.085% in total (about -4.4% a year). A funding rate is set anew for every payment; at this rate the next one is about −$2.23 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
