This market will resolve after Bulgaria is fully allowed to enter the Schengen area and resolves to "Yes" for that year.

After a year has passed, which doesn't see Bulgaria fully join, that year will be resolved as "No".

If there's no Schengen, this resolves to "N/A" for all unresolved years.

This market will prolong indefinitely. The market close date is there to help me close each unsuccessful year.
