Both sides work against this trade now: funding costs −$8 a day on $10k at the current rate, and Aftermath Perps is 0.041% cheaper against Phemex than usual: you would sell low and buy high (−$4 if the spread goes back to its 7-day average of +0.024%). Swap the legs. Mind the row above: over the last 3 days funding on this pair paid +0.072%, 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 0.072% in total (about 8.5% 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.
