Four Distinct Roles in Solo Quantitative Trading
Summary
The article divides solo trading work into four roles: researching whether a market effect is real, engineering a tradable strategy, building a portfolio from strategies, and operating the resulting system. Each role calls for a different focus, from open-ended investigation to repeatable daily execution. The author argues that switching deliberately between these roles can make problems easier to diagnose and prevent premature implementation work.
A central warning is to avoid strategy backtesting before understanding the underlying effect, its possible drivers, and its stability across market conditions. The article uses a bridge-design analogy to explain why understanding fundamentals should precede engineering. It offers no empirical tests or performance evidence; this is a practical framework for organizing research, rather than a trading strategy. Its claims are based on the author’s experience, and it does not prescribe specific research methods or operational procedures.
Key ideas
- Separate edge discovery, strategy testing, portfolio design, and trading operations into distinct work modes.
- Investigate an apparent market effect before optimizing a strategy around it.
- Strategy research should examine whether an effect can survive realistic costs and constraints.
- Portfolio research considers how strategies interact and how capital is allocated across them.
- Reliable operating processes connect research and portfolio decisions to real orders and position tracking.
