Stokker - Stock screener based on Spring-Boot/Integration + Elastic Search

NOTE: The source code corresponding to the Portfolio Manager has been moved to its own repository: https://github.com/victor-ferrer/stokker-portfolio-manager

Summary

This a personal learning project whose functionality, for the moment, is to:

• Gather historical stock quotations from Yahoo Finance
• Gather "live" stock quotations from Google Finance
• Index everything in a Elasticsearch node so queries, graphs and alarms can be generated.
• Provide an AngularJS web interface wrapping the Kibana dashboards.
• Provide portfolio management functionalities using the Stock prices stored in ES.

By "stock quotations", I mean:

• High, low, open and close values (daily values)
• Volume (daily)
• Ticker
• Timestamp of the current value

Desired functionality

• Be able to perform some studies in the indexed data in ES (specially, I´m waiting for some ES 2.0 features such as the moving average). This is a sample dashboard created with the information stored in ES and embedded in the AngularJS interface:

• Use the module "Watcher" in order to define several types of alerts based on market conditions.

On technical side:

• The latest Spring Boot version is to be used
• Application contains a DockerFile and can create an Docker image from it: -- This image can be associated with another images running more ElasticSearch nodes and the Kibana server
• Introduce OAuth2 as authentication system

This is how the deployment looks like:

• Stokker will read the stock information from the Web and will index it in an ElasticSearch cluster.
• The ElasticSearch cluster will be deployed either in its own Docker container or along with the Stokker JVM.
• Another Docker container will host Kibana
• Portfolio manager will host a local database with stock portolios, whose valuations will be calculated based on what is stored in the ES cluster.
• An AngularJS web interface will be shown to the user combining data from the local database and ES.

How to use it

Check this Wiki Page on how to run the project and its related tools.

Running example

There is a running instance of the application deployed in Heroku: https://stokker-portfolio-manager.herokuapp.com

My intention is that everytime that a succesfull CI build is finished, a new version is deployed to Heroku.

Please note that the Kibana functionality is not yet working in this environment.

Pending improvements

• Improve error reporting
• Provide a GUI with embedded Kibana visualizations
• And many more...
