Funding, last 4 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 +$15 a day on $10k at the current rate, and Kraken Futures is 0.195% dearer against Binance than usual: you sell high and buy low: +$19 more if the spread goes back to zero (this spread has no 7-day history yet). The two prices were read 54 seconds apart, so part of this spread may be the market moving, not a spread.
