English Summary

The article from SiamTP, dated September 25, 2026, outlines a structured approach to trading journaling designed to evaluate process improvement rather than merely tracking profit and loss outcomes. The core methodology emphasizes documenting the rationale for entry, market conditions, plan invalidation points, and risk sizing before executing any trade, which helps mitigate hindsight bias. A critical distinction is made between two separate questions: whether an order was profitable and whether it adhered to the established trading rules. The article stresses that these are independent variables, noting that rule-violating trades can be profitable while disciplined, rule-following trades can result in losses. To ensure data comparability, traders are advised to standardize their records by using consistent naming conventions for rules, system versions, instruments, timeframes, and cost calculations. When modifying trading rules, separate data sets should be maintained to prevent the mixing of results from different methodologies, which could render the data uninterpretable. The review process should focus on identifying recurring patterns of rule violations and associated costs, then selecting specific, testable issues for improvement. The article also recommends preserving out-of-sample test periods that were not used in system development, allowing for unbiased evaluation after implementing changes. This systematic approach to trade documentation enables traders to objectively assess whether their trading process is genuinely improving over time, separating emotional reactions to individual trade outcomes from meaningful analysis of their overall trading methodology and discipline.
