Both sides work against this trade now: funding costs −$13 a day on $10k at the current rate, and OKX is 0.123% cheaper against Aster than usual: you would sell low and buy high (−$12 if the spread goes back to its 7-day average of −0.050%). Swap the legs. Mind the row above: over the last 7 days funding on this pair paid +0.104%, 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 7 days it paid 0.104% in total (about 5.4% a year). A funding rate is set anew for every payment; at this rate the next one is about −$4.31 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
