Cryptocurrency Trading Bot - Python

I'm looking for a experienced Python developer to work on a cryptocurrency trading bot that follows an grid trading strategy. My priority is stability: the script should run for days on end without uncaught exceptions, memory leaks, or performance bottlenecks.

Deliverables
• Clean, well-commented Python code that executes the existing arbitrage logic reliably
• Robust try/except blocks and retry logic around all external calls
• A lightweight logging setup (console + rotating file) with clear, actionable messages
• A short README explaining everything new added.
