Both sides work against this trade now: funding costs −$17 a day on $10k at the current rate, and edgeX is 0.320% cheaper against BingX than usual: you would sell low and buy high (−$32 if the spread goes back to its 7-day average of −0.102%). Swap the legs. The two prices were read 55 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 -0.168% in total (about -8.8% a year). A funding rate is set anew for every payment; at this rate the next one is about −$2.91 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
