This project is a high-performance order execution and management system built to trade on the Deribit Testnet API. It includes a robust WebSocket server for real-time market data streaming, enabling seamless interaction between trading clients and the system.

• Place Orders: Submit buy or sell orders with configurable parameters like instrument, price, and amount.
• Cancel Orders: Efficiently cancel specific orders by their unique ID.
• Modify Orders: Dynamically update existing orders for price and quantity adjustments.
• Retrieve Open Orders: Fetch details of all active orders.

• Order Book Retrieval: Access real-time order book data for any trading instrument.
• View Positions: Display detailed information on current positions, including size, average price, and mark price.

• Client Connectivity: Supports multiple client connections via Boost.Asio and Boost.Beast.
• Dynamic Subscriptions: Allows clients to subscribe to specific symbols for real-time order book updates.
• Real-Time Broadcasting: Continuously streams live updates for subscribed symbols to all connected clients.

• C++: Core implementation language.
• Boost.Asio and Boost.Beast: For WebSocket server functionality.
• cURL: For making HTTP requests to the Deribit API.
• nlohmann/json: For JSON parsing and manipulation.

  • Boost (Asio and Beast)
  • cURL
  • nlohmann/json
• API Credentials: Generate client_id and client_secret from the Deribit Testnet.

1. Clone the repository:

   git clone https://github.com/Shubhammore71/deribit-trader-cpp
   cd deribit-trader-cpp

2. Compile the code:

   g++ -std=c++17 main.cpp websocket/server.cpp -o trading_system -lboost_system -lssl -lcrypto -lcurl

1. Execute the compiled binary:

   ./trading_system

2. The WebSocket server will run on the specified port, and trading operations will execute based on the implemented logic in main.cpp.

• Authenticate with the Deribit Testnet API to retrieve an access token.
• Use the access token to send authenticated requests for order execution, cancellation, and data retrieval.

• Listens for incoming connections and manages multiple clients.
• Handles subscriptions to specific trading symbols for order book updates.
• Broadcasts real-time market data updates to all connected clients based on their subscriptions.

placeOrder("buy", "100", accessToken, "1", "BTC-PERPETUAL");

cancelOrder("30454002197", accessToken);

getOrderBook("ETH-PERPETUAL", accessToken);

• Send: subscribe:BTC-PERPETUAL
• Server Response: Acknowledged: subscribe:BTC-PERPETUAL

• Enhance error handling and implement retry mechanisms for network failures.
• Extend WebSocket functionality to include additional data types like trades and positions.
• Optimize performance using multi-threading for handling high client traffic and lower latency.

This project showcases advanced C++ programming skills, expertise in WebSocket development, and proficiency in API integration. It is designed with modularity and scalability, making it a robust solution for real-time trading systems.
