Infrastructure that makes bypassing risk technically difficult.

The design is simple: Python and FastAPI are the only authority that may approve a trade. The MQL5 expert advisor is an execution bridge. The Next.js console and mobile app display state and request actions. They cannot change the math.

PostgreSQL holds balances of record, orders, fills, and audit. Redis holds live snapshots, queues, locks, and pub/sub. Losing Redis must not invent or erase a fill.

We build in small, testable modules — risk, copy, execution, and presentation — so a new strategy can be added without rewriting the platform, and a failed check always becomes TRADE_REJECTED.
