Funding, last 3 days (all we have)—no history yet

Price spread, last 7 days—no price history on both exchanges yet

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 Bybit is 0.137% dearer against GMX than usual: you sell high and buy low: +$14 more if the spread goes back to zero (this spread has no 7-day history yet). The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
