Together, before fees—needs both histories

Both sides work for this trade now. Funding pays +$3 a day on $10k at the current rate, and OKX is 0.053% dearer against ApeX Omni than usual: you sell high and buy low: +$5 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 −0.670%, so the current rate has only just turned in your favour. The two prices were read 90 seconds apart, so part of this spread may be the market moving, not a spread.
