Show the method. Explain the limits.

What we publish

Our learning guides explain financial mathematics and common market mechanisms. Calculators and Risk Lab models apply explicit rules to numbers the visitor chooses. None of this content is a personalized investment recommendation.

Original illustrations and examples

We make original educational charts and visual examples for topics such as cost basis, drawdowns, correlation, trade sequences and probability. Fictional price paths, candles and outcomes are identified as hypothetical; they are not presented as historical trading records or observed market prices.

Calculation testing and review

Calculator and risk-model source code is version controlled and supported by automated numerical and integration tests. Tests check specified formulas, input boundaries, known examples and certain accessibility and search-indexing conditions. A passing test suite is not proof that every possible input, browser or market condition has been covered. The site has also undergone owner-led visual reviews during development.

Sources and evidence

Where a guide describes instrument-specific rules, we aim to distinguish universal mathematics from terms set by a particular exchange and include direct documentation links when useful. Our Methodology page describes the currently implemented models; Data Sources explains why we do not publish unlicensed quote history or pretend simulated results are market research.

Limitations of authorship

Market History Lab is an independently developed educational project. We do not claim that every guide has undergone independent peer review or has been approved by a licensed financial adviser. Readers should verify financial rules against applicable professional and official information, particularly when real capital may be at risk.

Keeping explanations accurate

We revise content when errors or meaningful limitations are identified. Guide headers indicate their stated update date; revisions are not made solely to create an artificial appearance of freshness. To report a factual or calculation error or request a correction, write to contact@markethistorylab.com. Our Privacy Policy explains how messages are handled.
