Release history

V4.8 (latest stable) - 04/16/2013 (download)

  • This version fixes several issue with QuoteMedia data: new format would cause data download to fail or to be saved with the wrong sorting.

V4.6 - 07/15/2012 (download)

  • Fixes a Yahoo data issue: it checks if the downloaded data contains a last bar whose date is equal or lower than the previous bar, and if it does contain one, it removes it.
  • Fixes a bug in the symbols.exe utility causing it to fail when downloading any of the Nasdaq, NYSE or AMEX symbols lists.

  • To take full advantage of this fix, it is recommended that a one-time full reload of all data be done.

V4.5 - 07/07/2012 (download)

  • Fixes a Yahoo data issue: it checks if the downloaded data contains a duplicate last bar, and if it does contain one, it removes it.

  • To take full advantage of this fix, it is recommended that a one-time full reload of all data be done.

V4.4 - 05/12/2012 (download)

  • Fixes a data rounding bug.
    • Previously, values were rounded in some cases, causing some precision loss, as well as unnecessary data reloading in update mode.
    • This version saves the data exactly as it was downloaded with no rounding, which improves data precision and avoids unnecessary data reloading in update mode.

    To take full advantage of this fix, it is recommended that a one-time full reload of all data be done.

V4.3 - 05/09/2012 (download)

  • Fixes a data update bug.
    • Previously, during data update, YLoader would compare the last local bar with the same bar on the server to determine if there had been any changes that would require a complete data update. However, if a bar other than the last was different, the data was considered correct and no download was initiated.
    • The new version compares several bars to determine if there are inconsistencies, and thus correctly determines if data is incosistent and initiates a complete download in that case.
  • This version is more tolerant to hardware changes: it won�t request a new key if the system is upgraded with a just a new hard drive, video card etc. Major changes may still generate a new hardware fingerprint and require a new validation key.

V3.9 - 10/18/2011 (download)

  • New symbols files settings - optionally:
    • generate a list of symbols with errors during a session
    • ignore the list of symbols with errors during a session

  • changed the settings file location to prevent settings saving issues on Windows Vista and 7
  • changed the location of the initial sample symbols list file and data directory
  • new registration management commands

  • New general setting to not reload old data in update mode, even if that data is inconsistent with the new data, and the command line flag (-w) for this setting. This is normally used to avoid overwriting old data in case it has been manually changed.
