# Machine Learning for Trading, 3rd Edition
**Build, test, and deploy ML-driven trading strategies, from data sourcing to live execution.**
The code for [*Machine Learning for Trading, 3rd Edition*](https://amzn.to/4eigy2F) by
[Stefan Jansen](https://www.linkedin.com/in/applied-ai/): 27 chapters and nine case studies, rebuilt
from the ground up around one end-to-end workflow. How a research idea becomes a strategy you can
run, and keep running, in a live market.
**Looking for the second edition?** It is complete and stable on the `second-edition` branch:
`git checkout second-edition`, and everything is exactly where that book describes it.

## What's New in the Third Edition
The whole book traces one path: from data infrastructure and strategy research, across an *evidence boundary* that
separates tuning from evaluation, to deployment and monitoring, with a feedback loop that retrains, pauses, or
retires a strategy as its edge decays.
Where earlier editions moved technique by technique, the third edition runs that one process end to end, and adds
substantial new material:
- **A wider model toolkit**: from gradient boosting (XGBoost, LightGBM, CatBoost) to deep time-series architectures
(PatchTST, iTransformer, TSMixer, TCN, Mamba) and newer tabular and latent-factor models (TabPFN, TabM, conditional
and supervised autoencoders).
- **Dedicated strategy-design chapters**: transaction costs and risk management are now full chapters, neither of
which existed before, joining portfolio construction and strategy synthesis so a raw signal is carried through to a
sized, cost- and risk-aware portfolio.
- **A full production track**: live trading systems (Interactive Brokers, Alpaca, QuantConnect), MLOps and governance
(drift detection, safe rollout, circuit breakers, feature stores, experiment tracking), and the operational reality
of *running* strategies, not just building them.
- **Generative AI**: retrieval-augmented generation grounded in SEC filings, knowledge graphs and Graph RAG, and
autonomous, multi-agent research systems.
- **Causal machine learning**: Double ML, Bayesian structural time series, and causal discovery for separating real
effects from spurious correlation.
- **Reinforcement learning**: optimal execution, market making with inventory, and deep hedging.
- **Synthetic financial data**: TimeGAN, Tail-GAN, Sig-CWGAN, and diffusion-based generators for validation when
history is short.
Methodological rigor is treated as a first-class topic rather than an afterthought. The book draws an explicit line
between exploration and confirmation, the *evidence boundary*, uses walk-forward cross-validation throughout, and
confronts the multiple-testing and overfitting problems that quietly invalidate most backtests, with tools like the
Deflated Sharpe Ratio, the Rademacher Anti-Serum, and White's Reality Check, plus conformal prediction for honest
uncertainty estimates.
The data layer moves to **Polars** for fast, expression-based manipulation, and every chapter ships in **reproducible
Docker environments** so results repeat across machines; PyTorch, LightGBM, Optuna, and Plotly round out the modeling
and visualization stack.
### Nine Case Studies
The structural centerpiece of the third edition is **[nine case studies](case_studies/)** that run the length of the
book. ETFs, crypto
perpetuals, intraday equities, options, FX, futures, and equity factor panels are each carried through the *same*
pipeline, from raw data and labels to features, models, backtests, costs, risk overlays, and a final deployment
assessment. One disciplined process applied to nine very different markets shows where it works, where it breaks, and
why.
| Case Study | Asset Class | Frequency | What It Explores |

## The Code, Chapter by Chapter
One directory per chapter, each opening with a guide that maps the chapter's sections onto the
notebooks that implement them and lists the data each one needs. The book carries no code listings,
so these guides are where a chapter's implementation lives: read a chapter, then open its directory.
An introduction and a closing chapter bookend six workflow-aligned parts.
### Introduction
| Chapter | What it covers |
|---------|----------------|
| **[1. The Process Is Your Edge](01_process_is_edge/)** | Why process discipline beats model sophistication: the ML4T workflow as a research-to-production system, regime detection on factor returns and macro indicators, and the evidence boundary that separates exploration from confirmation. |
### Part I - Financial Data (Chapters 2-5)
The markets, instruments, and infrastructure the rest of the book builds on: a taxonomy of sources, raw exchange messages turned into feature-ready bars, point-in-time fundamentals, and synthetic histories for robust validation.

|---------|----------------|
| **[2. The Financial Data Universe](02_financial_data_universe/)** | Eight asset classes surveyed, survivorship bias quantified, storage formats benchmarked (Parquet, DuckDB, kdb+, TimescaleDB), and the data-quality framework used throughout the book. |
| **[3. Market Microstructure](03_market_microstructure/)** | NASDAQ ITCH parsing, limit order book reconstruction from several sources, Lee-Ready trade classification validated, and bar-sampling methods compared; dollar bars deliver the best return normality. |
| **[4. Fundamental and Alternative Data](04_fundamental_alternative_data/)** | Point-in-time SEC EDGAR pipelines, entity resolution across identifier systems, macro and commodity fundamentals, and alternative-data evaluation including on-chain crypto and prediction markets (Kalshi, Polymarket). |

### Part II - Research Design and Feature Engineering (Chapters 6-10)
Define the trading problem, then turn data into model-ready signals: research design, labels, features, and the evaluation that determines what any model can learn.
| Chapter | What it covers |
|---------|----------------|
| **[6. Strategy Research Framework](06_strategy_definition/)** | Universe rules, decision schedule, cost model, evaluation protocol, and run logging. Introduces the nine case studies and the walk-forward cross-validation discipline that anchors Chapters 7 to 20. |
| **[7. Defining the Learning Task](07_defining_the_learning_task/)** | Forward-return, triple-barrier, and trend-scanning labels; information coefficients, quantile analysis, and feasibility screens; multiple-testing control with BH-FDR and the Deflated Sharpe Ratio; causal plausibility checks. |
| **[8. Financial Feature Engineering](08_financial_features/)** | Five feature families from price (momentum, reversal, volatility, liquidity, microstructure), structural and cross-instrument features, macro and calendar context, and selection with robustness testing. |
| **[9. Model-Based Feature Extraction](09_model_based_features/)** | Features from fitted models: stationarity diagnostics, Kalman filters, Fourier and wavelet spectral features, GARCH volatility, and HMM regime probabilities, all point-in-time correct. |
| **[10. Text Feature Engineering](10_text_feature_engineering/)** | Bag-of-words through transformers: TF-IDF, Word2Vec and GloVe embeddings, LSTM sequence models, FinBERT sentiment, financial NER fine-tuning, and news-return signal construction. |
### Part III - Model Development (Chapters 11-15)
Five model families applied to the same nine case studies, each building on the linear baseline.
| Chapter | What it covers |
|---------|----------------|
| **[11. The ML Pipeline](11_ml_pipeline/)** | Ridge, LASSO, and Elastic Net as the baseline every later model must beat, logistic regression for direction, SHAP interpretability, conformal prediction for uncertainty, and a comparison across all nine case studies. |

Gradient Boosting and Advanced Tabular Models](12_gradient_boosting/)** | XGBoost, LightGBM, and CatBoost with Optuna multi-objective tuning, plus the deep tabular alternatives TabPFN and TabM. TreeSHAP explainability, and gradient boosting the strongest tabular model in most case studies. |
| **[13. Deep Learning for Time Series](13_dl_time_series/)** | LSTM, N-BEATS, PatchTST, iTransformer, TFT, TSMixer, TCN, and Mamba set against the LTSF-Linear debate, with a selection framework and cross-dataset evidence on when depth helps. |
| **[14. Latent Factor Models](14_latent_factors/)** | PCA eigenportfolios, IPCA with time-varying loadings, conditional and supervised autoencoders, adversarial SDF estimation, and yield-curve decomposition. |
| **[15. Causal Machine Learning](15_causal_estimation/)** | Double Machine Learning for isolating factor treatment effects, Bayesian Structural Time Series for event impact, and causal discovery with PCMCI, NOTEARS, and VAR-LiNGAM. |
### Part IV - Strategy Implementation (Chapters 16-20)
From predictions to deployable strategies: backtesting, portfolio construction, costs, risk, and synthesis.
| Chapter | What it covers |
|---------|----------------|
| **[16. Strategy Simulation](16_strategy_simulation/)** | Backtesting as falsification: trading-protocol specification, vectorized against event-driven engines, an ETF baseline, regime diagnostics, and overfitting control with the Deflated Sharpe Ratio, the Rademacher Anti-Serum, and White's Reality Check. |
| **[17. Portfolio Construction](17_portfolio_construction/)** | From scores to portfolios: mean-variance optimization and its pitfalls, Hierarchical Risk Parity, the Kelly criterion, conformal position sizing, deep allocation, and a controlled allocator comparison. |
| **[18. Transaction Costs](18_transaction_costs/)** | Cost taxonomy, spread estimation, market-impact calibration, execution algorithms (VWAP, TWAP, Almgren-Chriss), transaction-cost analysis, and breakeven costs that vary widely by asset class. |
| **[19. Risk Management](19_risk_management/)** | VaR and CVaR tail measurement, drawdown and path-risk controls, factor and sector decomposition, stress testing, adaptive risk overlays, deep hedging, and kill switches; overlay effectiveness turns out to be strategy-specific. |
| **[20. Strategy Synthesis](20_strategy_synthesis/)** | What nine experiments reveal about turning predictions into strategies: IC-Sharpe decorrelation, Fundamental Law diagnostics, the model-family cascade, cost-survival analysis, and holdout failure modes. |

## Quick Start
**New here? Read these three, in order.**
1. **[What this repository is, and what it is not](docs/what-this-is.md)** - what reproduces with
one command, what a configuration change buys you, what needs real compute or licensed data,
and what is not promised. Five minutes, before you install anything.
2. **[Installation](docs/installation.md)** - Linux, Windows WSL2, macOS, Docker, and GPU, in full.
3. **[Running notebooks](docs/running-notebooks.md)** - the case-study pipeline, the run log, and
how to experiment without disturbing the downloaded results.
Everything below is typed into a terminal on your own computer, not into GitHub, and run **from the
repository root**. New to the command line? Start with
**[Before You Begin](docs/installation.md#before-you-begin)**.
### 1. Clone and install
```bash
git clone https://github.com/stefan-jansen/machine-learning-for-trading.git
cd machine-learning-for-trading
cp .env.example .env # the defaults work as-is; nothing in it needs editing to start
```
Then pick one environment. **Option A, Docker**, carries every dependency and needs no compiler:
```bash
docker compose pull ml4t
```
**Option B, a local `uv` environment**, on macOS, Linux, or inside WSL2. Install `uv` with its own
installer, not with `pip`, which is missing or refuses to install on most current systems:
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
source $HOME/.local/bin/env # the installer's own line; puts uv on PATH here and now
uv sync
```
Option B compiles several dependencies from source, `scikit-learn` among them, so it needs a C/C++
compiler and the Python headers: `sudo apt install build-essential python3-dev` on Ubuntu, Debian
and WSL2, `xcode-select --install` on macOS. Budget about **16 GB** of disk (11 GB environment,
4 GB free datasets, 0.9 GB of git history).
| Platform | Take | Why |
|----------|------|-----|
| Linux | either | Both paths are exercised on every release |
| macOS, Apple Silicon | **B** | Walked on real hardware before each release. Docker there earns its disk only for the twelve pre-executed `ml4t-py312` notebooks, which have no arm64 build, and Chapter 2's containerized database benchmarks |
| macOS, Intel | **A** | PyTorch publishes no macOS x86_64 wheel, so the local path cannot resolve |
| Windows | either, **inside WSL2** | Run `wsl --install -d Ubuntu` from an Administrator PowerShell, restart, then run it a second time: the first run usually installs the WSL runtime without a distribution. Then follow the Linux instructions in the Ubuntu terminal. Installing into Windows Python is unsupported and does not work |
### 2. Download data
Most notebooks need datasets. Start with the free ones, which need no API keys:
```bash
uv run python data/download_all.py --free-only
```
That fetches seven datasets, about **4 GB** and twelve minutes, almost all of it the
firm-characteristics panel first needed in Chapter 4. To start in about 75 MB and fetch it when a
chapter asks:
```bash
uv run python data/download_all.py --free-only --skip-firm-characteristics
```
On the Docker path there is no host Python: run the same command without `uv run`, in the Jupyter
Lab terminal (**File → New → Terminal**). The **[data guide](data/README.md)** documents every
dataset, API-key setup, the loaders, and the storage tiers.
**Optional: pre-computed results.** To explore the nine released Chapter 11-20 case studies without
retraining, download their verified registries, predictions, model files, and backtest artifacts:
```bash
uv run python scripts/download_artifacts.py
```
### 3. Run notebooks
First confirm the install, with the one command that answers it. It prints a
PASS or FAIL line per component and exits non-zero on any required failure:
```bash
uv run python scripts/verify_installation.py # Option B
docker compose run --rm ml4t python scripts/verify_installation.py # Option A
```
Notebooks are paired [Jupytext](https://jupytext.readthedocs.io/) files, a `.py` source and a
generated `.ipynb`. `uv sync` already installed Jupyter Lab. Start it from the repository root,
on **one** of the two paths:
```bash
# Option B, local uv. Open the tokenized URL it prints, in full.
ML4T_DATA_PATH="${ML4T_DATA_PATH:-$PWD/data}" uv run jupyter lab
# Option A, Docker. Then open http://localhost:8888 in your browser, no token.
docker compose up ml4t
```
The `ML4T_DATA_PATH` prefix on the local path gives the loaders an absolute path, because Jupyter
runs each notebook with its chapter folder as the working directory and the loaders would otherwise
search inside that folder and report the datasets as missing. It keeps a value you have already
exported and defaults to this repository's `data/`. The Docker path needs no prefix: the compose
file sets the variable inside the container. See
**[running notebooks](docs/running-notebooks.md)** for the first-notebook walkthrough, case-study
pipelines, Papermill parameters, and the experiment workflow.
### Docker images
Most notebooks run on the default **ml4t** image; a few need a specialized one, and each such notebook says so in its
preamble. Full details in the **[Docker environments guide](envs/README.md)**.
| Image | Covers | When you need it |
|--------------|------------------------------------------------------------------|-------------------------|
| `ml4t` | All 27 chapters + 9 case studies (CPU) | Default for everything |
| `ml4t-gpu` | Same `ml4t` image, run with the NVIDIA runtime (`--profile gpu`) | Deep-learning chapters |
| `ml4t-py312` | Python 3.12 for signatory, esig, gensim, tfcausalimpact | ~10 notebooks |
| `benchmark` | Database clients (TimescaleDB, ClickHouse, QuestDB, InfluxDB) | Ch02 storage benchmarks |
| `rapids` | RAPIDS cuML + LightGBM CUDA (build locally) | One Ch12 GPU benchmark |

## Companion Resources
The [companion website](https://ml4trading.io) carries three things the chapters lean on but do not
reprint.
- **[112 primers](https://ml4trading.io/primer/)** are free, open explainers, one page per concept,
covering what a chapter assumes you already know: limit order book mechanics, bitemporal data
models, fractional differencing, multiple testing in factor research, conformal prediction, the
deflated Sharpe ratio, hierarchical risk parity, Almgren-Chriss execution, walk-forward
validation. Nothing to install and nothing to sign up for.
- **[61 agent skills](https://ml4trading.io/skills/)** are task recipes for coding agents, each
carrying the same guards against lookahead bias, leakage, and multiple testing that the task needs
when a person does it by hand. They span the research loop: building bars and triple-barrier
labels, feature selection, purged walk-forward CV, cost models and tear sheets, position sizing,
kill switches, live monitoring. Browsing the catalog is free; opening a skill's detail requires a
website account.
- **[Six Python libraries](https://ml4trading.io/libraries/)** carry the pipeline the notebooks are
built on, one per stage of the workflow. Each is a production package, documented and usable on
its own:
| Library | Stage | What it does |
|-------------------------------------------------------------|------------|--------------------------------------------------------------------------------|
| [`ml4t-data`](https://ml4trading.io/docs/data/) | Data | Unified market-data acquisition from 19+ providers behind one interface |
| [`ml4t-engineer`](https://ml4trading.io/docs/engineer/) | Signal | Features, labels, alternative bars, and leakage-safe dataset preparation |
| [`ml4t-models`](https://ml4trading.io/docs/models/) | Models | Finance-native latent factors, SDFs, direct prediction, and portfolio learning |
| [`ml4t-diagnostic`](https://ml4trading.io/docs/diagnostic/) | Evaluation | Feature validation, strategy diagnostics, and the Deflated Sharpe Ratio |
| [`ml4t-backtest`](https://ml4trading.io/docs/backtest/) | Strategy | Event-driven backtesting with realistic execution |
| [`ml4t-live`](https://ml4trading.io/docs/live/) | Deployment | Production trading with broker integrations |
