Diary of a Professional Commodity Trader: Lessons from 21 Weeks of Real Trading By Peter Lewis Brandt

Diary of a Professional Commodity Trader documents Peter L. Brandt’s application of classical charting principles to commodity and foreign exchange markets. The book combines an explanation of his Factor Trading Plan with a five-month trading diary, showing how chart interpretation, order placement, risk controls, and personal judgment interact during actual trading.

Brandt’s framework centers on breakouts from established chart formations, including head and shoulders, rectangles, triangles, and wedges. He explains how weekly and daily patterns inform trade selection, how anticipatory entries and pyramid positions differ from breakout entries, and how protective stops and position size determine exposure. Charts serve as a framework for organizing trades and managing uncertainty.

The diary records profitable trades, failed breakouts, missed opportunities, changes to the plan, and the emotional pressures of execution. Its practical value comes from showing how recognizable patterns evolve in real time, when outcomes remain uncertain and repeated losses can test a trader’s discipline.

The closing analysis evaluates results by signal category, pattern duration, and exit technique. Brandt examines weaknesses in his implementation and distinguishes potential improvements from changes that merely fit recent results. For traders developing a discretionary technical approach, the book connects chart analysis with the operating discipline required to implement and review a trading plan.
