Funding pays, the price is against you. Reya is 0.034% cheaper against Katana Perps than usual: you would sell low and buy high (spread −0.025% now, against its 7-day average of +0.010%). If the spread goes back, that is −$3 on $10k: about 28 hours of funding at the current rate (+$3 a day). At the pace of the last 3 days (+0.039% in total) that is about 2.8 days.
