Sources
We rely on official platform documentation, regulators' publications and our own worked examples. Each article shows when it was last updated.
Calculators
Every calculator uses one shared, automatically tested set of formulas. Fee rates are only shown as verified once we have checked them against the platform's official fee page.
Country status
Countries are listed as Available, Restricted or Not verified. We only mark a country Available after checking it, and we show the date of the last check.
Corrections
When we find an error we fix it and update the date on the page.
