™Primary-source foundation
Regulatory definitions and rules should be checked against agencies and self-regulatory organizations. Company-specific facts should be checked against public filings and official investor materials.
Trust & transparency
Sources & Methodology
Good financial education makes its evidence and limits visible.
Published by ET COMMERCE LLC d/b/a My Market BookReviewed November 5, 2026
Illustrations and examples
Simplified examples are labeled as illustrations. Charts should not imply historical performance unless they use accurate, identified data.
Evidence and conflicts
We prioritize regulators, official releases, company filings and instrument disclosures. Historical facts are separate from editorial interpretation. Hypothetical figures are labeled and calculations are checked. Commercial book links do not turn an educational example into a recommendation; no sponsored stock promotion is accepted.
A living methodology
Financial rules, market structure and product features change. Readers should verify current details with the relevant primary source or regulated provider.
AI-assisted production
AI assistance is used in drafting and formatting. Definitions, calculations and links are checked against primary-source material; ET Commerce LLC retains editorial and correction responsibility. AI systems and automated checks can miss errors and do not constitute independent professional certification.
Correction process
Send the page URL, disputed statement and relevant primary source to support@mymarketbook.com or use the contact form with a corrections subject. Material corrections are recorded in the correction log. We review the evidence before changing a statement and do not promise a result without investigation. The log describes the listed changes only; it is not certification of every page, independent expert approval or a promise that all errors have been found.

Corrections & updates
Material changes are recorded here with their original dates. Counts describe the site at the time of each entry.
Current book previews and source destinations
Synchronized the main book’s limited Dark and Light previews, chapter extract and edition records with the current R25 masters. Counts and chapter order are unchanged. Replaced five outdated SEC and Investor.gov source destinations. These asset and link checks do not constitute a new financial-content review of every lesson.
Policy clarity and buyer information
Reviewed the company and policy pages. Clarified education-only scope, possible errors, no guaranteed results, liability limits and non-waivable rights. Updated privacy descriptions for current browser-local learning features and added clearer final-sale, access and billing guidance. This policy review does not certify or re-review every financial lesson or publication.
Clearer navigation and editorial records
Added complete lesson jump links, a mobile lesson outline, a shorter Workshop address and clearer links to editorial evidence. Reorganized the existing correction history into dated entries. Improved financial-term search, storage recovery, book-page navigation and personal-printing clarity. Made Workshop interpretations more visible and differentiated the Headline Trap levels. Fixed Workshop search-result rendering and quiz progress recovery, including a save-before-restore race. Separated search data from the shared interface bundle. These presentation changes do not imply a new financial-content review of every lesson.
Curriculum and review coverage
Added 40 lessons, nine guided practice cases, topic-specific vocabulary and reading tasks, next-review dates and content classes. Published ten owner-supplied reader reviews across the shared commercial pages. Preserved the original routes, lessons and earlier corrections.
Historical market cases
Corrected the GameStop gamma-squeeze interpretation to match the SEC staff report. Clarified Netflix’s Russia suspension and Tesla’s noncash tax benefit. Separated editorial interpretation from measured consensus and claims about price causation.
Applied learning and calculation checks
Added applied challenges to the 33 lessons then published and specific qualifications to the 149 glossary entries then published. Strengthened assessment choices, execution-model validation and concentration terminology. Aligned learning paths and the free guide’s reward-to-risk notation. Added calculator validation and clarified matched/unmatched wash-sale basis, broker-transition wording and SEC reporting-period selection.
Risk, account rules and product descriptions
Corrected total-loss recovery handling; clarified risk-of-ruin and return assumptions; separated capital from risk in position sizing; updated federal-funds and ex-dividend terminology; replaced the former pattern-day-trader rule; corrected the option payoff example; and aligned product and public-download descriptions with the advertised book revision.
