Part 3: Machine Learning

Goal for this stage: From Models to Agents. Understand the proper use of machine learning in quantitative trading, and how to evolve from "prediction models" to "decision-making Agents."

After Completing This Stage

You will be able to:

  • Understand why "predicting price" is the wrong objective
  • Design proper labels (Triple Barrier Method)
  • Understand the core components of an Agent: State, Action, Reward, Environment
  • Build a single Agent strategy that generates trading signals
