1. Requirement Design

1.1 System Objectives

The goal of the spot quantitative contract copying system is to achieve the following points:

Automated Trading: Automatically execute trades based on preset quantitative strategies, avoiding manual intervention and reducing human operational errors.

Copy Trading Function: Allow users to follow specific experienced traders or strategies to execute trades, copying their successful operations.

Efficient Risk Control Mechanism: Control risks through mechanisms such as stop loss and take profit to ensure trading safety.

Strategy Diversity: Provide a variety of quantitative strategies (such as moving average strategies, arbitrage strategies, trend-following strategies, etc.) for users to choose and customize.

Real-Time Data Synchronization: Ensure the system can access market quotes in real time, responding and making decisions quickly.

1.2 Target Users

  • Retail Investors: Hope to reduce trading difficulty by following other successful traders or systematic quantitative strategies.

  • Professional Quantitative Traders: Earn commissions or income by sharing strategies and signals, and expand their trading influence.

  • Institutional Investors: Use the system for quantitative management and risk control of funds, increasing the yield of investment portfolios.

1.3 Technical Requirements

  • High Concurrency Processing Capability: The system needs to be able to handle a large number of user transaction instructions and data requests simultaneously.

  • Low Latency Trading: Ensure trading instructions are quickly transmitted to the exchange, especially the execution timeliness of contract trading is crucial.

  • Powerful Data Analysis Capability: Able to analyze market data in real time to optimize the execution effect of quantitative strategies.

2. Functional Design

2.1 Account Management

  • User Registration and Login: Support various methods of user registration and login, including email, phone number, third-party platform login, etc.

  • API Interface Management: Support users binding to the exchange's API for account fund management and automated trading.

  • Fund Management: Display account balance, available balance, used balance, and other information in real time, supporting multi-currency management.

  • Identity Authentication and Security: Strengthen the system's security by adopting two-step verification, API key encryption, and other methods to protect user funds and information security.

2.2 Quantitative Strategy Management

  • Strategy Selection and Creation: Provide ready-made quantitative strategy templates (such as moving average crossover strategies, grid trading strategies, etc.), while allowing users to customize strategies based on their needs.

  • Strategy Parameter Adjustment: Users can adjust the parameters of the strategies according to market conditions and personal needs, such as stop loss, take profit, fund allocation, etc.

  • Strategy Backtesting: Users can backtest strategies on historical data to evaluate their performance under different market conditions.

2.3 Copy Trading System

  • Copy Trading Selection: Users can choose to copy other successful traders or strategies, and the system displays traders' historical performance, trading style, and other information.

  • Copy Trading Parameter Settings: Users can set the fund ratio for copy trading, limit the number of copies, and set maximum loss limits.

  • Automatic Trade Copying: The system will automatically execute the same buy and sell operations in the user's account based on the copy trader's signals.

  • Profit Distribution: Traders and copy trading users can set profit distribution mechanisms, usually split based on a certain ratio.

2.4 Risk Control Management

  • Stop Loss and Take Profit Settings: Users can set stop loss and take profit points for each transaction to avoid substantial losses and lock in profits in a timely manner.

  • Dynamic Risk Control: Automatically adjust stop loss and take profit trigger points based on market fluctuations to avoid stop loss failures due to rapid market changes.

  • Risk Alert System: When a user's account experiences losses, liquidation, or other abnormal situations, the system will issue an alert to notify the user to take action promptly.

2.5 Real-Time Market and Trading Signals

  • Real-Time Market Data: The system provides comprehensive market data, including real-time prices, trading volumes, and order books for both spot and contract markets.

  • Trading Signal Push: Analyze market trends using AI technology to push trading signals to users, who can make decisions based on these signals.

  • Trading Records and Statistics: The system will detail the historical data of each trade and generate statistical reports to help users analyze their profits.

2.6 Data Analysis and Reporting

  • Profit Analysis: Display the user's historical profit situation, including profits from individual trades, total profit and loss, annualized returns, etc.

  • Strategy Analysis: For the quantitative strategies used, the system provides detailed performance analysis, including win rate, maximum drawdown, and other data.

  • Risk Control Analysis: Display the execution of strategies such as stop loss and take profit, as well as whether extreme situations such as liquidation occur.

3. System Architecture and Technical Logic

3.1 System Architecture

The spot quantitative contract copying system should adopt a distributed architecture to ensure high availability and scalability. Key modules include:

  • User Management Module: Responsible for user registration, login, identity authentication, and other functions.

  • Strategy Engine Module: Responsible for executing quantitative strategies, strategy backtesting, strategy optimization, etc.

  • Copy Trading Management Module: Responsible for scheduling and executing copy trading operations, synchronizing copy trading signals in real time.

  • Trade Execution Module: Interface with the exchange's API to submit trading instructions in real time.

  • Data Analysis Module: Process market data, historical trading records, etc., providing real-time analysis capabilities.

  • Risk Control Management Module: Responsible for risk monitoring, stop loss and take profit settings and execution.

3.2 Technology Selection

  • Backend Development: Use high concurrency, high-performance programming languages such as Go, Node.js, etc., to ensure low-latency trading for the system.

  • Database: Use distributed databases (such as MongoDB, PostgreSQL) to support massive trading data storage and querying.

  • API Interface: Interface with exchanges, supporting RESTful API or WebSocket API for quick data synchronization and trade execution.

  • Data Processing and Analysis: Use big data technologies (such as Hadoop, Spark) for real-time data processing and analysis, optimizing quantitative strategies.

  • Frontend Display: Use modern frontend frameworks like React, Vue to ensure the responsiveness and smoothness of the user interface.

4. Development and Testing

4.1 Development Process

  • Requirement Analysis: Define the system's functional and performance requirements based on market demand and user feedback.

  • Architecture Design: Design the system's technical architecture and database structure to ensure the system's efficiency and scalability.
