Editorial policy
The rules every page on this site follows before it is published.
Sources
Every number, date, rule and named organisation on a page must trace back to a source in our knowledge base. We grade sources:
- Primary (A): regulators, central banks, statistics agencies, laws and regulations, official registers, protocol documentation and peer-reviewed studies reporting their own data. Only these can support a number or a rule.
- Secondary (B): textbooks and reputable explainers. We use them for structure, never as the only source of a number.
- Our own view (C): clearly marked as opinion.
If we cannot find a primary source for a claim, we leave the claim out.
Checking
- Write from the knowledge base
The writer works only from source notes that record the exact figure and a short quote proving it.
- Calculate, do not estimate
Every worked example is calculated in code and the result is copied onto the page.
- Independent fact check
A second reviewer compares every number, date and rule on the page with the original source before it can be published.
- Automated gates
Our publishing script refuses pages that lack sources, contain promises of returns, have broken links or skip the beginner mistakes section.
What we never publish
- Promises of profit or income, or screenshots of wins.
- Buy, sell or hold calls on any asset.
- Rankings of brokers or exchanges without a public method.
- Paid or sponsored content.
Corrections
Send corrections through the contact page. We check the claim against the source, fix the page if we were wrong and note the change in the page's modified date.
