Fyers Option Data Automation Alerts

I need a developer who can pull live option-chain information—prices, traded volume, and open interest—from my Fyers account and stream it to a local application on my Windows PC. Once the data is in place, the program must watch for any crossover I define (for example a fast-slow moving average or a custom ratio) and immediately raise an alert. A desktop pop-up and a webhook or e-mail notification will be sufficient for the first version.

Here is how I picture the flow: the tool connects to the Fyers API or WebSocket, subscribes to the chosen symbols, stores the incoming feed in a lightweight local database or CSV directory for later analysis, and runs the crossover logic in real time. I want the alert rules to be editable from a simple configuration screen or JSON file so I can tweak thresholds without touching the code.

Deliverables
• A Python-based (or similar) script or small GUI app that authenticates with Fyers and streams option prices, volume, and open interest continuously.
• Real-time alert engine that fires on any user-defined crossover condition and logs the exact trigger time and values.
• Basic configuration panel / file plus clear setup instructions so I can run the tool on my PC without additional help.
• Short hand-off call or video walkthrough once you have a working build.

If you have already worked with Fyers or other broker APIs and can demonstrate reliable, low-latency data handling, I would love to see your approach and estimated turnaround time.
