I need a production-ready piece of software that automates live trading across three markets—Indian exchanges, global Forex, and Crypto—while letting multiple users trade from the same installation. The core must talk seamlessly to Zerodha, Interactive Brokers, and Binance on day one, yet stay open enough for me to plug in additional brokers later without rewriting the engine. The platform has to execute scalping, day-trading, and swing-trading strategies in real time. Order routing, position sizing, and risk controls should run at low latency, with WebSocket or FIX support wherever the broker allows. I also want a clean dashboard (web or desktop) where each user can: • connect his or her own API keys, • switch strategies on or off, • monitor live P&L, open orders, and logs. Deliverables 1. Trading engine with modular adapters for Zerodha, Interactive Brokers, and Binance. 2. Strategy layer that accepts scalping, day-trading, and swing-trading logic—sample templates included. 3. Multi-tenant dashboard for account management and real-time monitoring. 4. Step-by-step deployment guide plus commented source code. I will test the build with live and paper accounts; execution accuracy, reconcilable logs, and the ability to add a fourth broker without touching core files are my acceptance criteria.
