MockTrade Application

Lets get this out of the way, this app is very much a WIP and still has some roughness around the edges. All balances in the application are purely virtual and have no value in the real world. The author is not responsible for any virtual gains or loses that occur in the application.

Welcome to the MockTrade project!! This open source application is an Android based Trading Simulator. The application allows the user to create virtual portfolios and track performance over a period of time. The goal is to provide a basic learning trading tool to empower the next generation of investors.

Application Framework

The project includes the AppFramework Library which provides generic services to the MockTrade application. The AppFramework afforded me an opportunity to explore some Application Architecture ideas and apply them to the Android platform.

Highlights:

  • SqlConnection Service
    • sqlite encapsulation
    • SqlMapper pattern
    • auto id, create_time, and update_time column management
    • database creation and upgrade via SQL script assets
  • Model/View/Presenter Support
    • Model - Interfaces describing data retrieval and persistence functionality
      • abstracts data contract from data source model implementations that are managed by the framework.
    • View - Extends Android ViewGroup classes
      • caches controls (ViewHolder pattern)
      • provides Listener interfaces to communicate with Presenter
      • facilitates binding to Business/Domain Object patterns
    • Presenter - BaseAppCompatActivity classes to facilitate MVP
      • coordinates interactions between the View and Model
      • error handling framework for exceptions thrown from the Presenter.
      • provide system services to business logic
  • Metadata Driven Create/Edit screens
    • Annotations to define Labels and input types and restrictions
    • Supports custom control injection to allow for advanced functionality
    • ExternalController model to allow custom validation and advanced UI behavior

Next Steps

  • Investment/Account/Order Detail Screens
  • Gamification
  • Option Chains
