NSE Option Chain Comparative Dashboard

I need an automated pull of the NSE option chain that covers the current-week, next-week and current-month expiries. For each of those three segments I want the script to:

• grab every strike in the chain,
• add up the Call LTPs into one figure,
• add up the Put LTPs into another,
• present a clear side-by-side comparison so it is instantly obvious where the premium favours option sellers.

The raw chain, the strike-level breakdown and the three aggregated summaries should all land in a single file—Excel, CSV or even JSON is fine as long as it is tidy and clearly labelled.

I am comfortable if you work in Python with requests / pandas or any reliable API wrapper for NSE, but feel free to use another stack if it is stable. Just make sure the script can be rerun daily without manual tweaks and includes a brief README that explains:

1. how to change the date so it always targets the current and next expiries,
2. any dependencies to install,
3. the exact fields returned.

I will consider the job complete once I can run the code on my own machine and reproduce the three expiry summaries within a minute.
