Funding pays, the price is against you. Aster is 0.052% cheaper against Bluefin than usual: you would sell low and buy high (spread −0.029% now, against its 7-day average of +0.023%). If the spread goes back, that is −$5 on $10k: about 5 hours of funding at the current rate (+$26 a day). At the pace of the last 7 days (+0.239% in total) that is about 37 hours. 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 0.239% in total (about 12.5% 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.
