Trading Journal Research and Calculation Methodology

Review evidence dates, selected provider scope, exact arithmetic and the limits of our original journal.

Provider selection

Six established or accessible journaling workflows were selected to represent hosted import, free stock execution imports, manual entry and structured reflection. They are not ranked by promised trading performance. We use the provider’s own pages, distinguish plan-specific claims and mark unknown free entitlements explicitly.

Evidence and price conflicts

Sources are dated and linked. Current pricing/help pages take precedence over stale provider comparison articles. Monthly billing and annual upfront commitments are not treated as interchangeable. Promotions and location-dependent taxes are called out. Published claims do not establish tested integrations.

Original tool and reproducibility

The journal uses exact scaled-integer calculations for gross and net amounts, validates every record and rejects invalid whole imports. Independent decimal tests, browser interactions, export readback and responsive checks accompany publication. Synthetic examples are labelled and carry no investment recommendation.

Scope and privacy

One linear completed trade per row; no raw fill matching, futures settlement, option assignment, multi-leg lifecycle, currency conversion, tax reporting or broker access. Fees and risk are user inputs. Browser persistence is explicit and deletable. Full backups are your responsibility; clearing tab data does not delete an independently saved browser copy.
