UI Prototype

A preliminary user interface for Trump is being prototyped.

Web Interface

The web UI was born out of Flask, Jinja2 and Bootstrap "hello world".

Some screen shots, of the beginning, are below.

SQL-like search, is straight forward and as expected.

An example of symbol page, for a symbol with two feeds.

View the index, data, and do common analysis. Or, download to excel/csv...

Histograms and basic charting are available.

Overrides and failsafes, are what makes Trump amazing for business processes.

The last time a symbol was attempted, and successfully cached, are available.

Browse and cache sets of symbols, based on tags...

And, much, much more, coming soon...

Search

Trump's SymbolManager object, has basic/expected SQL-enabled search functionality.

The Trump UI prototype is boosted by an ElasticSearch server with a single index consisting of symbol, tag, description, and meta data. To add a symbol to the index, use the json created from Symbol.to_json().

ElasticSearch, makes searching much cooler...

Background Caching

Trump's caching process isn't blazing fast, which means using the UI to kick off caching of one or more symbols, requires a background process in order for the web interface to stay responsive.

A very simple RabbitMQ consumer application, is included with the UI, which listens for the instruction to cache. The python pika package is required.
