Python Supertrend Option Selling Algo

I need a Python-based algorithm that follows a directional, Supertrend-driven approach for option selling. The logic is strictly trend-following, and I only want the system to fire sell signals—no buys. Once in a position, it must manage exits automatically according to stop-loss, target, and end-of-day square-off rules that we will finalise together.

The code must connect to my Dhan brokerage account through their API. I’m not tied to any particular execution platform yet, so please recommend and set up whatever stack (cloud VPS, local server, Docker, etc.) you believe will keep latency low and reliability high.

Along with the core strategy, I expect:
• Robust error handling and logging so I can audit each trade
• Simple configuration for lot size, symbols, timeframe, Supertrend parameters, and risk controls
• A small dashboard or CLI script to start, stop, and monitor the bot
• Deployment and end-to-end testing on live (but small-size) orders before hand-over

Deliver the full, well-commented Python source, any helper scripts, and a short deployment guide so I can redeploy if needed. Quote me one transparent, all-inclusive price upfront—no back-channel renegotiations later.
