Inspiration

Making money. Just kidding.

We thought using the Symbl API would be fun and using the sentiment analysis feature on stocks was the first good idea that came to mind.

What it does

Stock Stalk is a Java application that allows users to perform sentiment analysis on any stock using Symbl.ai, Yahoo Finance, and News API.

Simply search for a stock ticker and allow Stock Stalk to provide you with its price, individual sentiment score of recent news articles, and average sentiment score. Sentiment scores range from -1.0 (negative) to 1.0 (positive).

You can also save your favorite stocks for easy access on the homepage!

How we built it

Stock Stalk was built entirely using Java.

Three APIs were used:

Yahoo Finance API to get stock information
News API to get the most recent news articles about a stock to run sentiment analysis on
Symbl API to run sentiment analysis on news articles

(Due to Symbl.ai only allowing for two concurrent jobs with a free account, only the two most recent news articles are used for the sentiment analysis. Upgrade your plan to get even more!)

The UI was created using Java Swing and designed using Figma.

Challenges we ran into

Getting the APIs to work with Java was the first challenge we ran into. We actually started our project with Java 1.8, but quickly realized it would be much easier with a newer version of Java.

Another challenge we ran into was creating the UI. Java Swing is not the easiest thing to learn and make good-looking UIs with so there were definitely many bugs and Google searches.

Lastly,

Accomplishments that we're proud of

As we had practically no past Java experience, finishing this project using only Java is an accomplishment we are extremely proud of. We are proud that we stuck with it and worked through the many challenges encountered along the way.

What we learned

A lot about Java, but even more about teamwork and planning.

What's next for Stock Stalk

We plan to add more sources to run sentiment analysis on, such as Twitter, Reddit, etc.

Some other features to add are: ticker autocomplete, using another UI framework, and adding even more stock information.

Mainly worked and learned about how to connect the various APIs to our program. This was challenging as it was my first time doing this. Also contributed to some parts of the UI. Was the video editor for this project.

I worked with the various APIs and created some GUI components. This was my first time using Java so it was quite challenging making Stock Stalk, but I definitely learned a lot and had lots of fun :)

Yifan Hao
I worked on the data handling and the UI. During this hackathon I learned how to use Java Swing, APIs, and other Java libraries such as File Writer :)

William Kang
Learned basic java as well as api calls and ui work and using figma to plan
