What do you plan to trade and how? I personally have kind of never seen the benefit of those Bloomberg terminals Everything you need is virtually free and simple.
I mean there might be some tool (programming like selenium etc), to make similar function of Bloomberg for wider selection of brokers, by himself.
Techinally, C# and selenium might be a choice. Tell me if there is a another alternative second choice.
A Bloomberg terminal provide a large analysis platform (RT and historical news and data, macro and micro information + analysis) like Metastock Xenith (for "retail" people) and a neutral Broker solution (...The "universal trading system") like Metastock Real Time, Multicharts, Sterling, eSignal etc...
Most traders can access "historical news and data, macro and micro information + analysis" by his own programming. Here neutral solution for "universal trading system" is important in this thread. Hope to change broker any day.
Probably you mean http://www.fixtradingcommunity.org/pg/structure/about/overview Too many brokers have all-different APIs, so that traders lose much (meaningless) time to adjust (change) his own program. Hope every brokers provide simple (and common) way 1) common method of feed (every 1-min) 2) get current position (every 1-min) 3) deliver a bunch of order (basket of 100 orders) in one-click.
