I'm not sure how the wholesale end of the data business works, but I believe
there are a limited number of wholesalers which feed data to the various real
time and EOD providers. A bulliten from DTN within past few days indicates they
use feed from Bridge. From the description of the BMI symbols, it would appear
that BMI might also be using Bridge while the Signal symbols appear to be
sourced elsewhere. If DTN and BMI are sharing the same feed, it is hard to see
how BMI can justify a basic setup and fee structure which is approximately twice
DTN's. Telescan's symbol structure is also quite similar. Would be interesting
to identify the wholesalers used by the various major providers.
