Well A. Thats not a date and
B. When is it determined you win?
I win after each incorrect date passes. If the price passes $24777 I lose.
It's not complicated, really.
Then your bet would have to be "None of the dates in the list". In this case, when all dates in the list fail, you win. Otherwise, you lose. No ambiguity.
"Never" is ambiguous, as has already been noted, and micgoossens was right in ignoring your post.
