I need a functional scalping tool that plugs directly into Zerodha, Interactive Brokers and exness so I can trade both the Indian and US markets from a single screen. The tool must be able to place, modify and cancel both buy and sell orders in real time via the official APIs (Kite Connect, IB API, exness API). Core features • Automated trading logic that I can switch on/off without restarting the program • Customizable alerts (sound, pop-up, or email) triggered by price, volume or trade events • Latency-focused order routing so entries and exits execute in milliseconds Scope of work 1. Build a clean, lightweight UI or command-line interface that lets me: – connect to each broker with my credentials – choose the instrument/exchange (NSE, BSE, NYSE, NASDAQ, etc.) – set position size, stop-loss and take-profit levels on the fly 2. Implement a strategy module where I can paste or load my own Python snippets to drive the scalping logic. 3. Provide a detailed setup guide and short video walkthrough showing the tool running live on both an Indian and a US symbol. 4. Include a functional prototype I can test on paper-trading/sandbox environments before we go live. Tech preferences Python is ideal because of existing libraries (kiteconnect, ibapi), but I’m open to C# or Node.js if you explain the benefits. The finished code must be clean, well-commented and easy to extend. Delivery expectations • Source code with README • Requirements.txt or equivalent dependency list • Demo script or notebook showing automated entry/exit and alert generation • Quick support after hand-over to fix any connection issues that appear in the first week of live trading If you’ve already integrated any of these brokers, mention it—proven low-latency work will stand out. Let’s build something fast, stable and easy to tweak.
