About The Project

Fidcoin stock trading is a web app that allows multiple users to practice trade stocks during market's opening time (9:30am - 4:00pm) on Wed, 14 July 2021 without using real money. A new user is given a default account with $10,000 virtual money and a watchlist of 05 random stocks. When the market closes at 4:00pm every day, all the orders are reset (deleted) so that user can restart the next day.

Due to the scope of this project, I couldn't purchase a paid account to get realtime data from broker platforms. My solution is to get historical data of 14/07/21 and let users only trade on that day. Data from backend is sent to frontend via websocket instead of http requests.

Built With

• Java 11
• Spring Boot 5.3.6
• Hibernate
• MySQL
• Angular 11
• WebSocket, StompJS
• Scheduler, Cron
• ApexChart.js
• YahooFinance
• Amazon Web Services (S3, EC2, NGINX)
• Testing with JUnit, Mockito

Features

• Execute market and limit orders. For limit orders, if the price reaches the pre-defined, the order will be filled and converted its status from "working" to "filled".

• Display the position of owned stocks, including their realtime P/L based on their current market value.

• If there's a new order, change in stock prices, account is immediately updated.

• Allow multiple users trading at the same time.

• When a user (e.g., U_001) purchases a stock (e.g AMZN), other users (e.g., U_002, U_003) will get a notification about U_001's transaction (e.g "U_001 has just purchased AMZN"). This feature is built by design pattern "Observable".

• Automatically schedule to cancel(delete) orders when the market closes at 4:00pm on every day without restarting the server.

• Display candle charts by using data from YahooFinance library to get historical quotes and ApexCharts.js to display the chart.

• Build a watchlist to track favourite companies. Perform CRUD (create, read, update, delete) operations and display realtime stock prices in the watchlist.

• Follow news related to the watchlist.

• Deploy frontend and backend on Amazon Web Service using S3, NGINX, and EC2.
