StoxKart XLS Trade

I already run a similar workflow with Zerodha and now want the same convenience on my StoxKart account. In short, the Python script must read my existing Excel sheet, pick up the manual trade instructions I enter there, and then:

• Place the trades on StoxKart exactly as specified

The XLS file format is straightforward—one row per order with dedicated columns for symbol, quantity, order type, price, etc. You are free to use pandas / openpyxl (or any solid alternative) for parsing, but the StoxKart side should rely on their official REST API so it remains stable.

Core flow I expect
1. Authenticate with StoxKart through an .env-based credential file.
2. Read the Excel sheet, validate each row, and flag any missing fields before submission.
3. Push the orders; capture and return the order IDs in the console plus write them back into a results column.
4. Fetch the updated cash balance after all orders complete and print/store it.

Deliverables
• Well-commented Python 3 code (single script or small module)
