The data given is as follows...

A list of Sports IDs is available here.

We are aware of the following specfic issues with the data

1. We occasionally have to re-settle a market. In these cases the volumes quoted may be inaccurate.
2. For Asian Handicaps and Markets such as Total Runs or Total Goals, there is no Settled Date on the market.
3. For Asian Handicaps, there is no indication of the handicap, although each line is a different event id.
4. With the introduction of Keep Bets at the end of 2008, some trades have subsequently been labelled as PE when they should in fact be IP. This is due the fact that the bets were matched in-play (IP) although they were placed pre-event (PE) using Keep Bets.
