Prop firm rules built in
Each preset carries the firm's daily loss and max loss for every account size, so a trader sees how many losing trades their risk allows before a breach, and a warning when one trade eats more than half the daily limit.
Six languages
English, Turkish, German, Spanish, French and Italian, with number and currency formats to match. Set the language in the code, or build one embed per language.
Light, fast, private
No cookies, no trackers, no web fonts, no API calls. The calculation runs in the visitor's browser, so the widget loads quickly and needs no consent banner.
