I need a straightforward yet rock-solid trading bot that can live on Binance around the clock. The core logic is a 100-level grid: as price drifts down it should accumulate positions level by level, then release them automatically on the ascent to the next level up. Everything has to flow through the official Binance API with secure key handling, low-latency order placement and sensible error recovery. Code & stack • Please write the bot in Python; that is my firm preference because I already use Python for other automation tasks and want to read or tweak the logic later. • Clear, modular structure and comments are important so maintenance is easy. Pairs & strategy tuning I do not have fixed trading pairs in mind and would value your market insight. Feel free to reco...

I’m building a truly mobile-first energy management system that must run smoothly on both iOS and Android from day one. The app will let end-users watch their energy usage in real time, control connected devices remotely, and pull clear consumption reports, all from their phones.

I’m open to expanding to social or biometric login later, but they are not part of this initial scope.
