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

Together, before fees—needs both histories

The price spread pays, funding is against you. ApeX Omni is 0.607% dearer against MEXC than usual: you sell high and buy low (spread +0.607% now, against zero (this spread has no 7-day history yet)): +$61 on $10k if it goes back. Holding the pair costs −$17 a day in funding at the current rate, which eats that in about 3.5 days. Mind the row above: over the last 7 days funding on this pair paid +0.658%, so the current rate has only just turned against you. The two prices were read 81 seconds apart, so part of this spread may be the market moving, not a spread.
