Both sides work against this trade now: funding costs −$26 a day on $10k at the current rate, and Aster is 0.215% cheaper against Kraken Futures than usual: you would sell low and buy high (−$21 if the spread goes back to its 7-day average of −0.054%). Swap the legs. The two prices were read 54 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 5 days it paid -0.363% in total (about -24.7% 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.
