I need a cross-platform mobile application (iOS and Android) that gives me full control over an automated trading robot built on Smart Money Concepts with a pure trend-following bias. The core logic already exists in theory but must be coded, stress-tested, and exposed through an intuitive mobile interface. When finished, I want to be able to: • connect live accounts on MetaTrader (both MT4 and MT5), Interactive Brokers (TWS/Gateway), and the exchange APIs for Binance, Bybit, and OKX; • adjust key SMC parameters—liquidity zones, order-block definitions, imbalance-fill rules, risk per trade, and overall exposure—directly from the phone; • trigger, pause, or close positions instantly and receive push notifications for entries, exits, and rule-based alerts; • view real-time P&L, equity curves, and a rolling log of executed orders; • back-test the strategy inside the app against historical data and export the results. I am open to your preferred tech stack but expect clean, well-commented code, secure key storage, and API-rate-limit awareness. A short hand-off video, build/run instructions, and unit-test coverage for the trading engine will complete the engagement.
