Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: MEXC is 0.441% cheaper against ApeX Omni than usual: you would sell low and buy high, −$44 on $10k if it goes back to its 7-day average of −0.023%. The two prices were read 96 seconds apart, so part of this spread may be the market moving, not a spread.
