Funding, last 5 days (all we have)—no history yet

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

Together, before fees—needs both histories

Funding pays, the price is against you. Polymarket Perps is 0.110% cheaper against HTX than usual: you would sell low and buy high (spread −0.110% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$11 on $10k: about 7.4 days of funding at the current rate (+$2 a day). The two prices were read 46 seconds apart, so part of this spread may be the market moving, not a spread.
