Together, before fees—needs both histories

Funding pays, the price is against you. Kraken Futures is 0.089% cheaper against MEXC than usual: you would sell low and buy high (spread −0.089% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$9 on $10k: about 4 hours of funding at the current rate (+$60 a day). The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
