Multi asset broker platform

The brief

The client needed a retail broker platform for forex, metals, crypto and indices, with demo and real accounts. Orders had to settle correctly even when no trader was online, and every movement of money had to be traceable.

What we built

• Web trading terminal with real time charts, indicators and drag to edit stop loss and take profit
• Server side risk engine that checks open trades and pending orders on every price tick
• Immutable ledger with statements, receipts and audited admin adjustments
• Binance futures routing and USDT deposit reconciliation
• Admin control room with page level staff permissions, KYC review and a full audit log
• TOTP two factor sign in, session management and email verification
• Installable PWA and a React Native Android app sharing the same client

Under the hood

Settlement runs in background workers with database row locks, so a stop loss triggers once and only once, even after a feed reconnect or a worker restart. A scheduled recovery pass replays any missed ticks.

Built with: React, TypeScript, Node.js, Express, PostgreSQL, Redis, BullMQ, WebSockets, Docker

Outcome

Live. We only publish results that the client has confirmed.
