The leXso Data-Retriever is a useful piece of software that allows its user to automatically record market data from the Betfair X-Hold'em and/or X-Blackjack Games (Standard and/or Turbo versions). Deciding what to record is up to you via the Preferences. Recorded data can easily be imported into Microsoft Excel for further analysis. It is a stand-alone program wrote in java, available to use on all OS platforms. The software does NOT require you to be browsing the Betfair/Betfair games website at the same time!
