Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: Aster is 0.089% cheaper against SunX than usual: you would sell low and buy high, −$9 on $10k if it goes back to its 7-day average of +0.186%. The two prices were read 56 seconds apart, so part of this spread may be the market moving, not a spread.
