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.
