IG Markets API Client for Rust

A comprehensive Rust client for interacting with the IG Markets trading API. This library provides a type-safe and ergonomic way to access IG Markets' REST and WebSocket APIs for trading and market data retrieval.

Overview

The IG Markets API Client for Rust is designed to provide a reliable and efficient interface to the IG Markets trading platform. It handles authentication, session management, and all API interactions while providing a clean, idiomatic Rust interface for developers.

Features

  • Authentication: Secure authentication with the IG Markets API including session refresh and account switching
  • Account Management: Access account information, balances, preferences, and activity history
  • Market Data: Retrieve market data, prices, instrument details, and historical prices
  • Order Management: Create, modify, and close positions and orders with various order types
  • Working Orders: Create, update, and manage working orders with support for limit and stop orders
  • Watchlists: Full CRUD operations for watchlists including adding/removing instruments
  • Client Sentiment: Access client sentiment data for single or multiple markets
  • Indicative Costs: Retrieve indicative costs and charges for opening, closing, or editing positions
  • Transaction History: Access detailed transaction and activity history
  • WebSocket Support: Real-time market data streaming via WebSocket connections
  • Advanced Rate Limiting: Sophisticated rate limiting with automatic backoff, concurrent request management, and explicit rate limit error handling
  • Fully Documented: Comprehensive documentation for all components and methods
  • Error Handling: Robust error handling and reporting with detailed error types
  • Type Safety: Strong type checking for API requests and responses
  • Async Support: Built with async/await for efficient non-blocking operations
  • Concurrency Management: Built-in semaphores and thread-safe primitives for handling concurrent API requests
  • Configurable: Flexible configuration options for different environments (demo/live)
  • Persistence: Optional database integration for storing historical data
  • Database Support: Integration with SQLx for storing and retrieving transaction data
  • Serialization Utilities: Custom serialization helpers for handling IG Markets API responses

Add this to your Cargo.toml:

[dependencies]
ig-client = "0.11.1"
tokio = { version = "1", features = ["full"] }  # For async runtime
dotenv = "0.15"                                 # For environment variable loading

Documentation

Comprehensive documentation is available for all components of the library. The documentation includes detailed explanations of all modules, structs, and functions, along with examples of how to use them.

API Documentation

You can access the API documentation on docs.rs or generate it locally with:

make doc-open

Architecture

The library is organized into several modules:

  • config: Configuration handling and environment variable loading
  • session: Authentication and session management
  • application: Core business logic and services
    • models: Data structures for API requests and responses
    • services: Service implementations for different API areas
  • transport: HTTP and WebSocket communication with the IG Markets API
  • utils: Utility functions for parsing, logging, etc.
  • error: Error types and handling

Benchmarking

make bench-show   # Show benchmark results

Rate Limiting

The library includes a sophisticated rate limiting system to comply with IG Markets API restrictions:

  • Multiple Rate Limit Types: Different limits for trading, non-trading, and historical data requests
  • Thread-Safe Implementation: Uses tokio::sync::Mutex for safe concurrent access
  • Automatic Backoff: Dynamically calculates wait times based on request history
  • Explicit Rate Limit Handling: Detects and handles rate limit errors from the API
  • Global Semaphore: Limits concurrent API requests to prevent overwhelming the API
  • Configurable Safety Margins: Adjustable safety margins to stay below API limits
  • Rate Limit Error Recovery: Automatic cooldown and recovery when rate limits are exceeded

Example of configuring rate limits:

// Create a configuration with custom rate limit settings
let config = Arc::new(Config::with_rate_limit_type(
    RateLimitType::NonTradingAccount,  // Type of rate limit to enforce
    0.8,                               // Safety margin (80% of actual limit)
));

// The rate limiter will automatically be used by all services
let http_client = IgHttpClientImpl::new(config.clone());
let auth = IgAuth::new(config.clone());

// When rate limits are exceeded, the system will automatically:
// 1. Detect the rate limit error from the API
// 2. Enforce a mandatory cooldown period
// 3. Gradually resume requests with appropriate delays
