I want to reproduce the MetaTrader 5 experience end-to-end on Android—client app, trading engine, backend services, and an admin panel that can also run on Android. The finished product must feel as natural and feature-rich as the real platform because I intend to use it for my own live trading practice. Core flow • When no position is open, the chart must stream real-time quotes from the market data API I will provide. • The instant I open a Buy or Sell, the price feed should detach from the live stream and drift realistically in the direction of the trade (simulating slippage, spread, and normal volatility). • On closing the order, the chart needs to transition smoothly back to the true market price without any visible jump. All calculations—margin, P/L, equity, free margin—have to mirror MT5 logic so that every tick, candle, and order update matches what I would expect on the actual terminal. Key features I must see • Real-time market data • Comprehensive charting tools Deliverables 1. Full Android source code (Java/Kotlin) with clean architecture and comments. 2. Signed, installable APK for testing. 3. Trading backend and Android-based admin panel with user, symbol, and risk management controls. 4. Clear build/run instructions plus Postman (or similar) collection for API endpoints. Acceptance The build will be considered complete when I can: – Open the app, receive live quotes, place market and pending orders, and watch the simulated price evolution in real time. – Verify margin and P/L calculations against the same trades on real MT5. – Log in to the admin panel, create users, change leverage, and restart the quote stream without downtime. Only developers who have already implemented trading logic, worked with MT4/MT5 or comparable platforms, and can demonstrate previous projects of similar depth should bid.
