IBUKI Financial Analytics

IBUKI Financial Analytics is an application builds financial models that integrate sophisticated mathematical modeling with the ability to compute on incoming real time data feeds. Furthermore, the models are defined using normal mathematical expressions.

Real Time Data Streams

Variables on Data Feeds

The variables of the modeling language are bound to data feeds. If these variables are bound to a finite feed (for example, they come from a table in a database) they are just time-series variables. If they are bound to ungoing feed we call them time-stream

Data Feeds

Data Feeds

A Data feed presents you with information whenever it has some new data. The length of time and the interval between the arrival of new data can depend on many factor. One special kind of data-feed is where you know before hand an upper bound on how many times you can ask it for data before it is "done". We view 1) a table returned as the result of a database query and 2) a row or column of a spreadsheet as a finite data-feed. Data Feeds that potentially never stop are called ongoing data-feeds. The modeling language treats all data-feeds the same. The important thing about ongoing data-feeds is that, in general, you get new data at random times but that every time a new piece of data arrives, your financial model needs to be recomputed! How do you define such a model? The IBUKI Financial Modeling Language answers that question and provides an environment in which the requred computation can happen.

The lowest level functions that operate on data-feeds are


Returns the thing waiting for the next piece of data


Returns True or False depending on if there is more data to come. This only returns False if you are at the end of a finite data-feed.


Closes the data-feed, meaning that you can no access data from the feed

Since feeds are returning data at randon times stream-next must be executes in an asyncronous enviroment.
