Source of IB Ownership Data

Does anyone know the source of such data, from such deprecated EClient API call (with reportType='ReportsOwnership')?

void reqFundamentalData (
int reqId,
Contract contract,
string reportType,
List< TagValue > fundamentalDataOptions
)

It cannot be the Thompson-Reuters Ownership data, as TR uses a 9-digit int for "OwnerId" while the IB API data has 10-char "OwnerId".

Anyone has the documentation of such legacy data? Thanks.

 

Have you also asked this question to IB directly? Surely they'll know where they get their data from.

 

I did. As expected, they simply replied that it was already deprecated and no longer supported.

 

That's a disappointing response from them. Obviously they want to make it difficult for you to actually use that deprecated method. If they hide that OwnerId number you won't be able to get any data they still might have in their databases.
I have never used IB's FundamentalData so I can't help you with it.

 

No problem Thanks for trying.
