Funding pays, the price is against you. BloFin is 0.087% cheaper against Extended than usual: you would sell low and buy high (spread −0.057% now, against its 7-day average of +0.030%). If the spread goes back, that is −$9 on $10k: about 3.0 days of funding at the current rate (+$3 a day). The two prices were read 74 seconds apart, so part of this spread may be the market moving, not a spread.
