Quality Control

Our Quality Control Systems

Both we and our data providers run dozens of automated checks to ensure that data quality remains high.

(We have heard from a data provider in the past that we reported more inaccuracies than all of their other customers combined. We take this seriously!)

Reporting a Possible Data Issue

Issues with data do occur for all data providers. There are no perfect data sets, but we are constantly helping our data providers to improve the quality of the data they provide to us.

Please send us a message with the following information:

  • The company name, ticker symbol, or name of the data series with the possible error
  • The reason you think the data is incorrect (a separate source with conflicting data is best, so we can evaluate the conflict)
  • A link to a page with the possible error (optional, but speeds the process)

Speed of Fixes

Issues that are under our complete control are generally fixed within 24 hours.

Because our data comes from external data providers, we do not have full control over how quickly corrections are entered.
