Detect new fundamentals in Research

I want to get the eps of a company and also the first date on which the eps was available in
quantopian fundamental data. Is this date available on per row basis for each company in the results?
For example, this result shows that MSFT eps for period ending on 2015-12-31 became available
in quantopian on 2016-02-03
This was found after executing queries for each day and comparing with the previous day.
Is there a fundamental column that can provide the needed date directly in the results?

As far as I understand fundamentals schema provides only the last reading per each company,
so if I can filter by some available_to_quantopians_since column, I will be able to get all companies whose
last eps became available in quantopian for the first time on the simulation_date

I also had hard time figuring out how to display dates in readable format instead of ints. Is there a better way
to do it?

Unfortunately, there isn't a better way right now to detect the changes. We have further investment in our fundamentals features in our backlog and I think some of those features might make solving this problem easier for you.

Thanks
Josh

MSFT eps was released to the public on Jan 28, Thu and became available in research on Feb 3, Wed.
Knowing that morningstar data is uploaded nightly my first guess is that the eps would be available on Feb 29 Fri.
Where does this lag come from? Is it artificially introduced because the data is free?

Thanks

There is no extra lag intentionally injected into the system due to the price. This is the same data we would use for trading Quantopan's own money.

There are a variety of explanations for why the data is not available the following day as your example shows. Some of them include:

  • Morningstar not processing the data on the day of the announcement
  • Delays from Morningstar in making their files available to us
  • Delays on Quantopian's part in properly processing the data

Or a combination of the above.

Thank you
