I need a smooth bridge between my Kotak Neo account and Microsoft Excel so I can watch live option prices and fire orders without leaving the sheet. The core of the job is a Python backend that speaks to the Kotak Neo API and an Excel front-end that shows real-time data and lets me trade. Here is exactly what I’m after: • A Python script (cleanly structured, commented) that authenticates with Kotak Neo, opens the WebSocket for live market data, and uses REST for order placement and cancellation. • An Excel workbook wired to that script. Option prices and Greeks should stream into dedicated cells instantly—no noticeable lag—while order status updates in place. • In-sheet controls (buttons, formulas, or minimal VBA, whichever is simpler) that let me submit, modify, and cancel option orders straight from Excel. • Easy configuration: API keys, symbols, and quantity should sit in a settings sheet or JSON so I can tweak them without touching code. • Clear setup notes plus a short screen-share or video walkthrough so I can replicate the install on another PC. Acceptance criteria 1. Bid/ask for at least one option contract updates in real time when the market is open. 2. A test order placed from Excel appears immediately in my Kotak Neo order book and its status reflects back in the sheet. 3. No hard-coded paths; project runs after I change only the config file and keys. If this pilot works, I may add trade history and reporting later, but right now the focus is real-time feed and trade execution. Let me know your experience with Excel automation, Python (pandas, openpyxl, websockets), and brokerage APIs, and we’ll get started.
