Yes, sorry for dragging up the past, but I came across your thread in looking for a solution, so I figured it made sense to keep the discussion in one place.
Unfortunately your solution wouldn't work for me, as I want to record all winners roughly in order, so deleting a market wouldn't work for my purposes.
I want to be able to identify a winner even if another market has started. Am I on the right track with creating a list of favourites near the off that is added to each time a new market is opened. If so, do you have any pointers how to go about that, and how to query the list?
