The goal of our project is to understand the impact of social media posts on the future prices of individual stocks. We examined the impact of posts in the social media platform reddit.com within investment focused subreddits/forums using textual analysis techniques.

The files found here can be used to clean and apply sentiment to reddit posts and comments as well as create regression models using this data. We are also supplying the code which can be used for the interactive web application that is used to visualize real time sentiment and prediction for specific stocks tickers.

All analysis and data collection is found within CODE/Analysis

Obtain reddit comments and posts from google big query. https://bigquery.cloud.google.com/dataset/fh-bigquery:reddit_posts?pli=1

Example queries for May 2018. Each table represents 1 month. Repeat as necessary.

SELECT * FROM fh-bigquery.reddit_posts.2018_05 where subreddit = 'wallstreetbets'; 
SELECT * FROM fh-bigquery:reddit_comments.2018_05 WHERE subreddit = 'wallstreetbets';

Place .csv files from big query into respective folders.

Run the following files in order.

The following fuctionalities were hosted on one ubuntu server hosted by digitalocean.

The python script under CODE/liztd_python_load is setup as a cronjob to be executed every night.

This is handled by the python script inside CODE/liztd_python_stream folder. This script has an open connection to monitor reddit 'wallstreetbets' stream and upload them into the mongodb database.

PM2 - PM2 is a process mangement tool which is setup to keep the jobs running the scheduled time for data collection.

API:
    The python bottlepy based web server is hosted as an api to the database and the frontend. The project is present in CODE/liztd_python_api

UI: 
    The UI is created using ReactjS, evergreen library for UI components and Recharts for charting components. The scripts neccessary to run the web ui are 
    present at CODE/liztd_ui/readme.md file.
