Price spread, last 7 days—no price history on both exchanges yet

Together, before fees—needs both histories

Funding between these two exchanges is close to zero, so right now this pair is about the price spread alone: SunX is 0.112% dearer against Polymarket Perps than usual: you sell high and buy low, +$11 on $10k if it goes back to zero (this spread has no 7-day history yet). The two prices were read 50 seconds apart, so part of this spread may be the market moving, not a spread.
