Both sides work against this trade now: funding costs −$19 a day on $10k at the current rate, and Entropy is 0.142% cheaper against edgeX than usual: you would sell low and buy high (−$14 if the spread goes back to its 7-day average of +0.095%). Swap the legs. The two prices were read 48 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 -0.160% in total (about -8.4% 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.
