Purpose and boundaries
MarketDeck publishes research and educational material. Our articles do not provide personalised investment, legal or tax advice and do not promise returns. A link to a tool is an invitation to explore its available research features, not an endorsement of a security or strategy.
Sources and original work
Guides link to original filings, official documentation, standards bodies, data-provider definitions and research papers where applicable. Worked examples are labelled as hypothetical. An author's reported research finding is distinguished from an independently reproduced result; these guides do not claim the latter.
AI assistance and authorship
The September 2026 field guides were prepared with AI assistance for research, writing, diagrams and implementation. MarketDeck is the publisher. No fictitious human analyst, review board, qualification or first-hand trading record is assigned to the articles. Source checks and automated arithmetic tests are not substitutes for independent professional review.
Dates, definitions and uncertainty
Updated dates reflect substantive changes, not a cosmetic attempt to look current. Provider definitions, legal rules and market conventions can change. Verify current primary documentation before relying on a time-sensitive point. Where a source was accessible only through an indexed extract, its source note states that limitation.
Corrections and limitations
A useful correction identifies the article, the disputed passage and the primary evidence supporting the change. Use the contact destination displayed on the MarketDeck homepage when available. We do not claim an always-staffed corrections desk or a response-time guarantee. Material corrections should be documented alongside the affected source and update date.
Search and publication quality
Keywords help us understand readers' questions; they do not replace research. We avoid copied competitor prose, artificial traffic claims, invented performance statistics and publishing empty category pages. Reader FAQs are for clarity, not promises of a particular search-result appearance.
