Just an idea ...
Using Excel as the data collecting interface via DDE to Reuters IDNDDE,
BridgeStation, Open Bloomberg (which provides free Excel Link), FS,
and almost all of the Internet feeds, for both real-time and EOD. Excel
itself is the basic development platform. By Excel Link for Mathematica
(or Matlab, Statistica, etc.) you could achieve almost anything regarding
computation, modeling, and simulation. Both Excel and Mathematica are
quite open, robust, and fully tested and supported (not only within the
financial world) and will not easily get obsolete or discontinued. This
kind of schemes or much more complex ones are actually applied by
some institutions for derivatives markets modeling and evaluation.
So, why not take this scheme as trader's operating system/environment?
Feed vendors just have to care about their data quality, delivery
efficiency,
contents, and devise a reliable, efficient data managers linked to Excel.
Developers concentrated on implementing/designing their indicators, trading
systems, special purpose fuctions or add-ons on this general platform, and
end users just spend their efforts evaluating what solutions are to their
purpose and utilizing them to the best.
Really tired of real-time datafeed availability and compatibility. And
another
2.5 years wait for a software to go from 16-bit to 32-bit (this time 32-bit
to
64-bit, maybe. You know what product I mean).
Feasible?
