Historical Data Quality Standards

 This data is a faithful reflection of data retrieved through use of the betfair API. This means data will reflect any technical issues experienced during use of the API 6.0, which has since been retired. The existing data has been cleaned and checked, and any sub-standard events have either been removed, or their price discounted.

Data is guaranteed to meet the quality standards described below. If any data available fails to meet them you will be informed at the point of purchase, or your money refunded.

The data will be at a granularity of less than 2 seconds for over 85% of the valid times shown in the data table.

In general most of the downloads will include longer pre-inplay market data than specified.

Missing data

There are a number of possible reasons that a market may not be available:

  • We may not have that market in our product range. The pricing information shows the sport types and market types that we try to provide. If your market is not listed here, please contact us, and we will consider making it available if we have it.
  • The market may have failed to record successfully. We wash the data we record, and sometimes, due perhaps to connectivity issues or other reasons, the data does not make it through this process.
  • Markets are not added immediately to the downloadable products (they are first washed and scrutinised to make sure they pass quality standards). It may be simply that you must wait (usually no more than 24 hours) before the market is available.
