Both sides work against this trade now: funding costs −$10 a day on $10k at the current rate, and Aftermath Perps is 0.026% cheaper against HTX than usual: you would sell low and buy high (−$3 if the spread goes back to its 7-day average of +0.038%). Swap the legs. Mind the row above: over the last 3 days funding on this pair paid +0.077%, so the current rate has only just turned against you. The two prices were read 50 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 3 days it paid 0.077% in total (about 9.0% 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.
