Automate NIFTY Options Strategy

I already trade a rule-based strategy on NIFTY weekly options and now want it converted into a fully automated algorithm that runs 24 × 7 on a cloud/VPS so I never need to keep a PC or laptop switched on. All monitoring, start/stop controls and emergency square-off must be possible from my mobile.

The system has to plug directly into the Angel Broking API and handle, without manual intervention:
• Automatic entry and exit
• Stop-loss and target setting
• Trailing stop-loss

Development flow I expect
1. One-year historical back-test with clear performance metrics
2. Paper-trading phase to confirm live behaviour
3. Final live deployment on the cloud/VPS you recommend

I will retain full ownership of the strategy and source code; please outline how you will ensure confidentiality.

Kindly include in your proposal:
• Total development cost, broken by milestones
• Monthly cloud/VPS expense for a 24 × 7 setup and any preferred providers
• Ongoing maintenance/support charges (if any)
• Estimated timeline for each stage
• Confirmation that all required Angel Broking API features are supported
• How the mobile dashboard or app will let me monitor, pause, resume, and square-off positions instantly

If additional broker APIs can be accommodated, feel free to mention them as optional add-ons, but Angel integration is mandatory.

I’m ready to move ahead as soon as I have a clear plan, cost sheet, and timeline.
