Methodology
B-NKER is a platform for traders and investors: an economic calendar built from official sources, prop firm rules quoted word for word, comparators and calculators. Every figure carries its source and its date.
Where values come from
Every value comes from the firm's own public page: rules page, FAQ, terms or announcement. We keep the exact sentence that states the value and the address of the page. A value without a quote is not published.
How a value is checked
Every critical rule (targets, daily loss, maximum loss, minimum days, news, EAs, consistency) is read by two AI models. When their readings differ, or one of them is unsure, a third AI model arbitrates. The code then checks the proof: the quote found word for word in the archived copy of the official page, and every number of the value found in the quote. Nothing is published without that proof.
Dates and history
Each value carries the date it took effect and the date we recorded it. Versions are never overwritten: a new version is added, so you can read the rules that applied on any past date.
Collection
We only collect pages whose owner allows it. Firms that do not allow automated reading are checked by hand and marked as such on their page.
Order of lists
Lists are sorted by the criterion you choose, or alphabetically. No firm can pay to move up.
Economic calendar
Where dates come from
Each release on the calendar comes from the official calendar of the institution that publishes it (statistical agency or central bank), and links to it. No line is copied from another calendar.
Importance rule
High: rate decisions of the major central banks, US inflation and employment, advance GDP, euro area flash inflation. Medium: the other major monthly indicators. Low: the rest. The rule will be recalibrated on measured market volatility once a licensed price feed is in place.
Times
Times are stored in UTC with the time zone of the source, and shown in yours. Around the clock changes (Europe on 25 October 2026, United States on 1 November 2026) the gap between New York and Paris is one hour shorter for a week.
Prop firm marks
A release is marked for a firm only when the firm's quoted news rule targets it. When a firm keeps its own list of announcements, we link to its rule instead of guessing.
