Issues with Free Data

• Free Services vs Subscription Services
• Free services generally do not provide for the
  following services needed to maintain a total
  return data base current over the years.
• BackFills
• Need to refresh old data often to fill missing
  quotes, correct errors, and provide recent data
  for days you missed a download.
• Changes to History
• Update symbols for new symbols, mergers, new
  names, delistings
• Adjust quote histories for distributions, splits,
  dividends.
• Importing to Charting Program
• Usually this is an extra step. Avoid using a
  downloaded database and a redundant charting
  program database.
• Time spent in performing these tasks may be
  large if you track many securities - and worth
  the price of the subscription.
