Fact-Checking Policy
How claims on this site are sourced, verified and dated — and what we do about figures that change over time.
Last updated: 2026-09-01
Source hierarchy
In order of preference:
- Primary sources — regulators, exchanges' own documentation, central banks, standard-setting bodies, published academic work.
- Reputable secondary sources — established financial press and industry research, used for context rather than for load-bearing facts.
- Nothing else. We do not cite other educational sites, aggregators, social media, or content of unclear provenance.
What must be sourced
Any statement that is not definitional or arithmetic. "A limit order fills at your price or better" is definitional. "Regulator X caps retail leverage at Y" is a claim, and it needs a link to the regulator.
Where we describe how something typically behaves rather than how it must behave, the text says so — "often", "typically", "on most venues" — rather than presenting a tendency as a rule.
Figures that change
Fees, leverage limits, supported countries, licensing status and product availability all change. Our approach:
- Prefer linking the primary source over restating the number.
- Where a number must appear, it carries the date it was checked.
- Anything unverifiable is left out rather than approximated.
This is why no exchange's fee schedule is published on this site. See how exchange fees work.
What we will not do
- Invent statistics, or repeat one whose original source cannot be found
- Cite a figure without a date when the figure is time-sensitive
- Present a backtested or hypothetical result as an actual outcome
- Attribute a claim to "studies" or "research" without naming the study
- Publish a review of a venue we have not checked against primary sources
Verification of exchange records
Every exchange record carries a verification date and the list of source URLs it was checked against. Both are displayed on the review page. A record without them is not published, and no referral link renders for it.
Reporting an error
If you find something wrong, tell us. Corrections are handled under the correction policy — publicly, dated, and saying what changed.
