This is a good idea but as others have highlighted the issue will be with data quality. At TagniFi we've been pretty vocal about the quality of the XBRL data because we find a lot of errors. Using the XBRL data directly from the SEC is the equivalent of drinking pond water since there is very little validation occurring[1]. This has resulted in a significant number of errors that will need to be corrected before consuming the data. We've automated some of this error correction but there are still quite a few that need human involvement. We also run all of the data through hundreds of QA checks to ensure data quality in the absence of validation. [1] http://www.tagnifi.com/dont-drink-the-pond-water/ |
