Daniel and Luci,
Craig Bauling here.

Thanks for your comments about the differences between Mathematica and Finance Platform. Posting on the Community is a great way to start a dialogue about topics like this, and your post has already caught the attention of the marketing team.

There are a number of key features that differentiate Wolfram Finance Platform from the other Mathematica licenses. While the Bloomberg link gets the most attention, there are other key features that uniquely support our Wolfram Finance Platform customers.  The two I think are most beneficial are:

1. A large set of dedicated GPU parallelized functions that serve the Financial marketplace, and 
2. The inclusion of the Enterprise license functionality.

Regarding 1), your computations take less time to process without needing your development team to create advanced functions. This saves time in development as well as during processing.

Regarding 2), the built-in Enterprise functionality allows users to create interactive reporting systems and to create models with advanced CDF features. Wolfram Finance Platform users can deploy CDF applications that allow non-Mathematica users to import their own datasets, interact using textual inputs (as opposed to only sliders, checkboxes and radio-buttons), and in the end, either publish reports or export the results in various file formats; without your users having to have Mathematica or to know Mathematica code.

The result is that we are seeing a lot of excitement around the Wolfram Finance Platform’s functionality and its ability to support business reporting  systems.

Hi all, I can understand these products now. Thanks for your help. everyone

Thanks for kind replies.

I would like to ask more questions and do not know much about Bloomberg Subscription and Bloomberg data.
Does the Bloomberg data provided through Bloomberg Subscription also include the information (such as specific company’s trading volume and real-time stock price) of individual companies included in the KOSPI and KOSDAQ of Korea?

You may wish to contact Wolfram Technical Support (https://www.wolfram.com/support/contact/) or a sales person for an official answers about the features of the Finance Platform. They may also be able to help you get a trial version of it.

The full list of features available in the Finance Platform that are not available in Mathematica is here: https://www.wolfram.com/finance-platform/features.
.
The Finance Platform allows you to connect to a Bloomberg subscription, but it does not come with a Bloomberg subscription. That must be bought separately. The Bloomberg subscription will need to be able to access KOSDAQ and KOSPI in real time in order for the Finance Platform to use the data in real time. Bloomberg itself would probably be the best place to look for information about whether the Bloomberg subscription has this data, but I would guess that it is available through their subscription service.
