Together, before fees—needs both histories

Both sides work for this trade now. Funding pays +$33 a day on $10k at the current rate, and MEXC is 0.617% dearer against ApeX Omni than usual: you sell high and buy low: +$62 more if the spread goes back to zero (this spread has no 7-day history yet). Mind the row above: over the last 7 days funding on this pair cost −0.658%, so the current rate has only just turned in your favour. The two prices were read 96 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 -0.658% in total (about -34.3% 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.
