With VIX at $15.70, July $12.50 calls were $3.00x$3.40. With VIX up to $16.45, the options are up to $3.20x$3.60. My platform says delta should be 1.00, but obviously the price seems to have little to do with that. And the July 10 calls have been $5.60x$6.00 all day. How do people trade these things if they have no relation to the underlying?
