A Feedback-Control View of Technical Analysis and Position Management
Summary
The article reframes technical analysis as a control problem in which analysis and position management operate together. Rather than focusing mainly on predicting turning points, it asks how positions should change as market conditions and the account’s current results evolve. The core relationship maps price changes into changes in trading results through position size; the author then proposes applying that transformation repeatedly in vertical layers or combining multiple systems horizontally.
This framework allows internal or auxiliary systems to influence real positions, and describes feedback from current system results as a way to adjust exposure. It also raises practical issues such as synchronization, discretization, spread, drawdown boundaries, and the risk that a controller overshoots its target. The article offers conceptual examples, including systems that use pseudo-random inputs, and characterizes the ideas as field-tested, but supplies no systematic performance measurements or comparative evidence. The many-layer, many-system construction is exploratory and can be difficult to interpret, so it should not be read as a validated trading strategy or a substitute for risk controls.
Key ideas
- The article treats trading as a control process that links market changes to account outcomes through position size.
- It proposes feedback that adjusts positions using the system’s current state and results.
- Trading systems can be layered vertically or combined horizontally, with auxiliary systems influencing live ones.
- Spread, discretization, synchronization, and controller overshoot can materially affect implementation.
- The concepts are exploratory and lack systematic performance evidence in the document.
