Trading Engine Crate
Overview
The trading_engine crate provides the high-performance core infrastructure essential for High-Frequency Trading (HFT) operations. It focuses on ultra-low latency execution, precise timing, and efficient order management to handle demanding market conditions.
Features
- Extreme Performance Optimization: Utilizes RDTSC for precise timing, CPU affinity for dedicated core execution, and SIMD instructions for vectorized data processing.
- Robust Order Management: Manages the lifecycle of orders, from placement to execution and cancellation, ensuring accuracy and low-latency updates.
- Flexible Execution Engine: Implements a highly optimized engine capable of processing trading strategies and executing orders across various venues.
- Multi-Broker Connectivity: Seamlessly integrates with multiple brokers, including Interactive Brokers and ICMarkets, via specialized adapters.
- Event-Sourced Architecture: Employs event sourcing for deterministic state reconstruction, coupled with comprehensive metrics and persistent storage.
- Concurrent Lock-Free Data Structures: Leverages advanced lock-free data structures to minimize contention and maximize throughput in multi-threaded environments.
Architecture
The trading_engine is structured around several key components:
- Execution Core: The central logic for strategy evaluation and trade decision-making.
- Order Manager: Handles all order-related operations, maintaining order state and communicating with broker adapters.
- Broker Adapters: Abstract interfaces and concrete implementations for connecting to specific trading venues (e.g.,
IbAdapter,IcMarketsAdapter). - Performance Utilities: Modules for RDTSC access, CPU core pinning, and SIMD instruction sets.
- Event Store: A mechanism for recording all significant events, enabling replay and auditability.
- Metrics System: Collects and reports performance and operational statistics.
- Persistence Layer: Stores critical state and event data for recovery and analysis.
- Concurrency Primitives: Custom lock-free queues, rings, and other data structures.
Usage
To initialize the trading engine and place a simple order:
use trading_engine::{
engine::TradingEngine,
order::{Order, OrderSide, OrderType},
broker::BrokerType,
};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut engine = TradingEngine::new();
engine.connect_broker(BrokerType::InteractiveBrokers).await?;
let order = Order {
symbol: "ESZ23".to_string(),
side: OrderSide::Buy,
order_type: OrderType::Limit,
quantity: 1,
price: Some(4500.0),
// ... other order details
};
let order_id = engine.place_order(order).await?;
println!("Placed order with ID: {}", order_id);
Ok(())
}
Testing
To run the tests for the trading_engine crate:
cargo test --package trading_engine
