HFTBacktest: A Comprehensive High-Frequency Trading Backtesting Tool in Python and Rust

Introduction to HFTBacktest

HFTBacktest is an advanced framework designed for developing high-frequency trading (HFT) and market-making strategies. This powerful tool provides accurate market replay-based backtesting by utilizing full order book and trade tick feed data. Originally written in Python, the framework has been completely rewritten in Rust to enhance performance and support new experimental features.

Key Features of HFTBacktest

This cutting-edge trading bot simulator offers:

• Tick-by-tick simulation with customizable time intervals
• Complete order book reconstruction based on L2 and L3 market data feeds
• Latency-aware backtesting that accounts for both feed and order delays
• Queue position modeling for realistic order fill simulation
• Multi-asset and multi-exchange strategy testing
• Live trading bot deployment for Binance Futures and Bybit (Rust-only)

Getting Started with HFTBacktest

Installation Guide

HFTBacktest supports Python 3.10+ and can be installed via pip or cloned directly from GitHub:

git clone https://github.com/nkaz001/hftbacktest

Data Requirements

The framework requires specific data formats for optimal performance:

• Full order book snapshots
• Trade tick data
• Market-by-price (MBP) or market-by-order (MBO) feeds

Sample datasets are available through project supporters for quick testing.

Core Functionality Explained

Market Making Algorithm Example

Here's a concise example demonstrating HFTBacktest's market making capabilities:

@njit
def market_making_algo(hbt):
    asset_no = 0
    tick_size = hbt.depth(asset_no).tick_size
    lot_size = hbt.depth(asset_no).lot_size
    
    while hbt.elapse(10_000_000) == 0:
        hbt.clear_inactive_orders(asset_no)
        depth = hbt.depth(asset_no)
        mid_price = (depth.best_bid + depth.best_ask) / 2.0
        # Additional strategy logic here
        # ...
        return True

This snippet shows the basic structure for implementing a market making strategy with position management and order queuing.

Frequently Asked Questions

What makes HFTBacktest different from other backtesting tools?

HFTBacktest specializes in high-frequency scenarios with:

• Microsecond-level simulation precision
• Realistic order queue modeling
• Comprehensive latency accounting
• Full order book reconstruction

Can I use HFTBacktest for live trading?

Yes, the Rust version supports live trading deployment for Binance Futures and Bybit, allowing seamless transition from backtest to production.

What programming skills do I need to use HFTBacktest effectively?

While Python knowledge suffices for basic usage, advanced features benefit from:

• Understanding of algorithmic trading concepts
• Basic Rust programming (for live trading)
• Familiarity with market microstructure

How resource-intensive is HFTBacktest?

The Rust implementation offers significantly better performance than pure Python solutions, though processing full tick data still requires substantial computing resources for large-scale simulations.

Where can I find sample datasets to test with?

The project provides sample data through supporter-hosted repositories, with documentation on preparing custom datasets for specific needs.
