Upstox Intraday Auto-Trading Bot

I run an active intraday desk on Upstox and want to take my fastest-moving scalping rules out of the spreadsheet and into a fully automated workflow. The goal is a bot (or tightly written API layer) that logs in to my Upstox account, listens to live market data, and fires orders within milliseconds once the scalping signals hit their thresholds—no manual clicks involved.

Core scope
• Market: strictly intraday equity and index instruments, required options logic for this build.
• Strategy: I have my own stratagy to deploy for bot
• Functionality: automatic trade execution with position sizing pulled from a config file so I can tweak quantities without touching the code.

Tech expectations
Python is preferred because I already host other scripts on a VPS, but I am open to Node or Go if you can justify the latency edge. You should be comfortable with the official Upstox REST & WebSocket APIs, token refresh handling, and basic fail-safe techniques (e.g., order acknowledgement checks, reconnect logic).

Deliverables
1. Well-commented source code ready to run on a Linux VPS
2. README covering setup, environment variables, and parameter tuning
3. One short live session (screen-share) where we place and square off a trade to prove full automation

Acceptance criteria
• End-to-end run executes at least 20 test orders in paper mode without manual intervention
• Average round-trip latency from signal to order < 300 ms on my VPS
• Error handling logs every event to a text file and raises an alert if an order is rejected

If you have built similar intraday bots for Upstox or other Indian brokers, tell me what KPIs you hit and let’s get this running.
