About restrictions. Two different lists. A venue that does not serve a country simply will not take the trade. A country whose regulator prohibits a venue may penalise the person using it. Both hide the trade button; only the second is a warning. The lists are maintained by hand and may lag a regulator.

How the ranking works

A weighted composite over metrics grouped by provenance. Half the weight sits on figures venues report about themselves; the other half on what Predxy measures or derives by comparing venues, which a venue cannot influence.

Each metric is converted to its percentile among the venues that reported it, then weighted. Percentile rather than min-max, so one outsized venue does not flatten the rest of the board. A metric a venue does not report is excluded from its score rather than counted as zero, and the shortfall is published as 'coverage'.

sum(points) / coverage = score
