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

The price spread sits at zero (this spread has no 7-day history yet), so right now this pair is about funding alone: −$3 a day on $10k at the current rate. The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
