What you'll learn
Fix the research setup before running models
Write the universe, labels, cost model and validation protocol into one file that every stage reads.
Build each stage on the one before it
Run feasibility, labels, features and feature evaluation in order, so models start from tested inputs.
Log every run and score the holdout once
Record each model and backtest by its configuration, then test the chosen strategy on held-back data.
Why this topic matters
A trading example often shows a model and a backtest. A complete study also fixes the universe, costs and validation protocol before any model runs, tests whether the data can support the question, evaluates features before modeling, and holds back a final period until the end. This lesson walks through one study from the Machine Learning for Trading (ML4T) companion code, stage by stage.
