Hello is there a way to detect that a company has filed a new quarterly or end of year report?
I can currently retrieve some line items of my choice from a list of companies of my choice and classify them by date. For example i am retrieving reported data from 2016 and estimated data from 2017 (since not all companies have filed their 2017 10K form).
I would like to create a scheduled task that would analyse if the 10-K has been added and rerun my code only for those companies who have updates. That way i would be able to update my info and read 2016+2017 reported data and start using the estimates of 2018. Same thing for quarterly reports.
I would like to know this not only for US companies but for other companies listed in nikkei or london stock exchange. Is this possible?
Best regards
