Every feature in a production trading system has an origin story — a paper, a theorem, a decades-old insight from probability theory or market microstructure. This post catalogs 14 ML features implemented in a Rust crypto scalping engine, traces each back to its foundational research, shows the actual formulas, and includes real production code. The engine processes limit order book (LOB) snapshots, trade ticks, and funding rate data in real time to generate scalping signals for crypto perpetual futures.

One of the core ideas in quantitative finance is that model predictions—often called “scores”—can be mapped to expected returns on an instrument. In Qlib, these scores are evaluated using metrics like the Information Coefficient (IC) and Rank IC to show how well the scores predict future returns. Essentially, the higher the score, the more profit the instruments—if your IC is positive and statistically significant, the highest-scored stocks should, on average, outperform the lower-scored ones.

Qlib is an AI-oriented, open-source platform from Microsoft that simplifies the entire quantitative finance process. By leveraging PyTorch, Qlib can seamlessly integrate modern neural networks—like Multi-Layer Perceptrons (MLPs)—to process large datasets, engineer alpha factors, and run flexible backtests. In this post, we focus on a PyTorch MLP pipeline for Alpha360 data in the US market, examining a single YAML configuration that unifies data ingestion, model training, and performance evaluation.

In the realm of quantitative finance, machine learning and deep learning are revolutionizing how researchers and traders discover alpha, manage portfolios, and adapt to market shifts. Qlib by Microsoft is a powerful open-source framework that merges AI techniques with end-to-end finance workflows.

This article demonstrates how Qlib automates an AI-driven quant workflow—from data ingestion and feature engineering to model training and backtesting—using a single YAML configuration for a LightGBM model. Specifically, we’ll explore the AI-centric aspects of how qrun orchestrates the entire pipeline and highlight best practices for leveraging advanced ML models in your quantitative strategies.
