YM Dow mini data


Daily data for Dow-mini reflects old (March contracts). Since rollover was last week, is it possible to use the current contract data (June 07)?

Thanks.
The contracts are reported separately.

The engineers are trying to think of a way of making this more obvious like putting a link to the new contract above the old contract so hopefully this will be less confusing in the future.
