Upstox Pro has been a reliable companion in my trading journey, especially with its fast order execution and sleek, easy-to-navigate interface. I liked how customisable the charts were, which made technical analysis a lot smoother. For their mobile app, my one-word review is "responsive"; I could monitor and trade while walking without hiccups. That said, I did face occasional glitches during peak market hours, which could be stressful when timing is everything, and that's the only factor where Upstox needs to pay attention. It’s a powerful platform for active traders who value speed and tools, which requires you to be prepared for the occasional tech hiccup.
