    I'm printing out the results of my Dow-based system each day since about 2 months (with, not the WL-developer). Because of the partially random share-selection (if you have more signals than positions to take) I get slightly different results each day. That's ok for me.

    BUT: Since last week things have changed dramatically !
    My profits for the 1 year - run, which were more or less the same since the beginning of April, decreased by a factor of two !

    Did WL change the data provider ? And have data-record been changed even in the past ?
    Any other suggestions ?

    Thanks, pri
