01 / Overview
Overview
Signal services sell screenshots of wins, and a trader cannot tell whether an entry or a stop was recorded before the outcome or after it, so Vantrex versions every signal and withholds its public history page until a real production record exists. The bilingual Next.js portal has working sign-up and sign-in and a subscription-gated dashboard; its checkout is built but not wired in production, and a separate Python engine shares the Postgres schema through a workspace package.

03 / Where it stands
Where it stands
The portal is deployed at vantrex-ten.vercel.app in English and Khmer, and sign-up and sign-in run against a real database. Checkout is not wired (no active plans and no webhook in production) and a new account's dashboard is empty: no users, no payments, and no track record published.
