greenerblue / tradebackend Goto Github PK

The goal of this project is to build a backend application which simulates trade matching in a stock exchange.

All the incoming orders are processed, cleaned and stored in the database table ordertb. A running instance of PostgreSQL server is present.

• Gradle provides the dependencies and build platform

• Main package contains two classes

  • DBConnect - Helps connect to the database and methods are provided which return the fetched records as an ArrayList.
  • Project1Application - Runs the matching algorithm and SpringBoot REST service which provides the query endpoint.

• The package controller has all the classes and interfaces necessary for communicating with SpringBoot for the restful service

• The package data has two classes, which are bound to the Orders (unmatched records) and Trades (matched records).

• PostgreSQL JDBC connects to the database

• DBConnect.createDatabases() and DBConnect.fillDbWithValues() can be executed first to ensure that the databases are created and have test values randomly generated and populated.

All data can be queried at localhost:8080 by appending the following:

• /api/stock/<stockname> | To get orders matching a given stock name
• /api/party/<partyname> | To get orders initiated a given party
• /api/price/<price> | To get orders matching the price
• /api/action/<action> | To filter orders by buy or sell
• /api/match/stock/<name> | To get the matched trades for given stock name
• /api/match/buyer/<name> | To get matched orders for a given buyer
• /api/match/sellerer/<name> | To get matched orders for a given seller
• /api/match/price/<price> | To get the matched trades matching the price
• /shutdown | Shuts down the application
