Funding pays, the price is against you. Bullet is 0.055% cheaper against MEXC than usual: you would sell low and buy high (spread −0.048% now, against its 7-day average of +0.007%). If the spread goes back, that is −$5 on $10k: about 4.0 days of funding at the current rate (+$1 a day). At the pace of the last 3 days (+0.009% in total) that is about 19 days. The two prices were read 45 seconds apart, so part of this spread may be the market moving, not a spread.
