The authentication layer handles full user registration with OTP email verification, login with JWT tokens, and complete session management across multiple devices. Identity verification is built in with a full KYC workflow that supports document submission, admin review, approval and rejection, and automatic expiry after two years. Two-factor authentication is included using Google Authenticator with QR code generation, enabling and disabling from the account settings.

The wallet system tracks balances and supports withdrawal requests with a full state machine covering seven stages from submission to completion, including automatic balance refund on rejection. Every action on the platform is recorded in an immutable audit log with timestamps and full details, and a financial ledger tracks the balance before and after every transaction to ensure complete auditability.

The trading engine is the core of the system. It includes a real-time price feed for thirty financial instruments covering forex pairs, metals, energy, indices, and cryptocurrency. The order book manages buy and sell orders with support for market, limit, and stop order types. The matching engine executes trades instantly with partial fill support. The risk engine calculates margin requirements, enforces leverage limits, and handles automatic liquidation. Position management handles opening and closing trades with real-time profit and loss tracking, stop loss, take profit, and daily swap calculations. The OHLC engine generates candlestick data across seven timeframes from one minute to daily, and WebSocket streaming broadcasts all price and candle updates to connected clients in real time.

The copy trading system is a complete, standalone module. Experienced traders can register as strategy providers and set their own commission rate. Other users can follow them and have all trades copied automatically with proportional allocation based on their chosen copy amount. The system includes a performance leaderboard ranked by profit and loss, a commission engine that transfers earnings automatically on every profitable copied trade, a risk filter that prevents copying when margin is insufficient, a queue worker for reliable high-volume processing, and a retry handler that recovers failed copy attempts automatically. On server restart, a sync service reconciles all open positions and copy relationships to ensure nothing is lost.

The entire system is built with Node.js, Express, and PostgreSQL, and exposes forty-five REST API endpoints plus a WebSocket server for real-time communication.

This is not a prototype. It is a fully tested backend built to production standards, and it is available for licensing, integration, or acquisition.
