I tried crypto volatility tracker mainly for scalping, and I was impressed with how responsive it felt. Having access to real-time market depth and tick charts helped me catch micro-movements I’d usually miss. The algorithm itself is quite flexible—you can adjust it based on your strategy, which I haven't seen in many free tools. I also used the Telegram integration for alerts, which kept me in the loop without needing to sit in front of the screen the whole time.
