Start trading your virtual market today.

Overview

Ultimate Stock Market Simulation Framework is a complete and extensible financial simulation engine built with Unity.

It replicates a real-time trading environment — with order book mechanics, AI traders, dynamic news feeds, and narrative market events — making it ideal for:

Financial & business simulation games
Trading education or training apps
AI trading experiments and backtesting prototypes
Fintech visualization and marketing demos

Everything is modular, event-driven, and fully customizable.

Core Features

Real-Time Trading Engine

Full order book mechanics (limit / market orders, partial fills, cancellations)
Thread-safe order matching with coroutine-based parallel processing
Configurable batch processor for high-frequency trading performance

AI Trader & Market Maker

Multiple AI trader types: AITrader, SimpleCommandTrader, MarketMaker
Realistic market participation, liquidity simulation, and command-based manipulation
Fully extensible — add your own trading agents easily

Dynamic News & Social Media System

Event-driven news articles and simulated social posts
Influencers and sentiment-driven reactions
Integrated with Scenario System for organic storytelling

Scenario & Event Framework

JSON-defined narrative events (time, stock, or random triggers)
Event actions: publish news, modify prices, post SNS, issue trader commands
Full control of in-game macro events and crisis simulations

Character & Relic System

Select trader archetypes (AntTrader, MemeTrader, etc.)
Each character has unique trading traits
Collect relics with gameplay bonuses (profit boost, fee reduction, early news)

Modular & Scalable Architecture

Manager-based system with dependency-safe initialization
EventManager for decoupled communication between systems
Easy integration with your own UI, data, or gameplay extensions

System Architecture Highlights

Event-Driven Architecture — clean Observer pattern communication
Object Pooling — efficient reuse of SNS posts, order rows, and events
Parallel Processing — each stock trades in its own coroutine
Data-Driven Design — scenarios and company info via JSON and ScriptableObjects
Expandable Modules — add new stocks, AI traders, or relics without modifying core logic

Includes full documentation with diagrams and an AI assistant guide for developers.
