Phase 6 · Professional trading

Phase 6 introduction

Professional trading. Turn individual trades into a durable trading system with risk controls, portfolios, execution, attribution, and review.

What this phase establishes

The first five phases concerned a trade or a strategy. Professionals manage a system: multiple positions, multiple strategies, risk rules, an execution process, and a continuously updated journal.

You should be able to explain where today's risk sits, whether a portfolio is genuinely diversified, why you made money this month, and whether profitable trades were good decisions.

Six chapters

Foundation capstone

Manage a $100,000 virtual portfolio end to end, with at least one full review cycle (daily, weekly, monthly), and submit:

  • Positions, risk budgets, and risk-control rules
  • Trade Cards and journals for every trade
  • Monthly attribution: contributions from direction, signal, Carry, execution, and fees
  • A review distinguishing sound decisions from good luck

Assessment emphasizes decision quality, risk control, and process discipline rather than profit. See the Foundation capstone handbook.
