Both sides work against this trade now: funding costs −$7 a day on $10k at the current rate, and Perpl is 0.036% cheaper against Reya than usual: you would sell low and buy high (−$4 if the spread goes back to its 7-day average of +0.055%). Swap the legs. Mind the row above: over the last 3 days funding on this pair paid +0.074%, so the current rate has only just turned against you.

The current funding rate is far above what this pair has been paying: over the last 3 days it paid 0.074% in total (about 8.7% 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.
