Fast Crypto Options Pricing

A high-performance, real-time cryptocurrency options pricing system built in C++ with a focus on low latency and efficient market data processing.

🎯 Overview

This system provides end-to-end infrastructure for cryptocurrency options pricing, from real-time market data ingestion to sophisticated pricing calculations. It's designed for high-frequency trading environments where microsecond-level performance matters.

Key Features

• Real-time Market Data: WebSocket connectivity to major crypto exchanges
• High-Performance Processing: Optimized C++20 codebase with SIMD JSON parsing
• Low-Latency IPC: Unix domain sockets for inter-process communication
• Live Orderbook Management: Efficient price level tracking and BBO calculation
• Options Pricing Engine: Advanced mathematical models for derivative pricing
• Modular Architecture: Clean separation of concerns for maintainability
• Production Ready: Comprehensive testing and robust error handling

🚀 Quick Start

Prerequisites

• C++20 compatible compiler (GCC 10+, Clang 12+)
• Bazel 6.0+ for build system
• Linux/macOS (Unix domain sockets)
• Internet connection for market data

Building the Project

# Clone the repository
git clone https://github.com/27sanjeevd/Fast-Crypto-Options-Pricing.git
cd Fast-Crypto-Options-Pricing

# Build the main application
bazel build //:main

# Build all modules
bazel build //...

# Run tests
bazel test //...

Running the System

# Run the main application (connects to crypto.com)
bazel run //:main

# Run individual components for testing
bazel run //IPCConnection:IPCConnectionTest
bazel run //FeedProcessing:FeedProcessingTest

Basic Usage Example

#include "ExchangeConnectivity/ExchangeConnectivity.h"
#include "FeedProcessing/FeedProcessing.h"

int main() {
    // 1. Connect to exchange and start receiving data
    std::vector<std::string> tickers = {"BTCUSD-PERP", "ETHUSD-PERP"};
    ExchangeWebsocketClient client(tickers, {"/tmp/market_data.sock"});
    client.Start();
    
    // 2. Process incoming market data
    FeedProcessing processor("/tmp/market_data.sock", "/tmp/bbo_output.sock");
    std::thread processing_thread([&]() { processor.Run(); });
    
    // 3. System runs continuously processing real-time data
    std::this_thread::sleep_for(std::chrono::hours(24));
    
    // 4. Graceful shutdown
    client.Stop();
    processing_thread.join();
    return 0;
}

🔧 Configuration

Exchange Configuration

Modify connection parameters in ExchangeConnectivity/ExchangeConnectivity.cpp:

const std::string HOST = "stream.crypto.com";
const std::string PORT = "443";
const std::string TARGET = "/exchange/v1/market";

Trading Instruments

Configure instruments in your main application:

std::vector<std::string> tickers = {
    "BTCUSD-PERP",    // Bitcoin perpetual futures
    "ETHUSD-PERP",    // Ethereum perpetual futures
    "BTC_USDT",       // Bitcoin spot
    "ETH_USDT"        // Ethereum spot
};

const std::string MARKET_DATA_SOCKET = "/tmp/market_data.sock";
const std::string BBO_OUTPUT_SOCKET = "/tmp/bbo_output.sock";  
const std::string PRICING_INPUT_SOCKET = "/tmp/pricing_input.sock";
