The slipping on standard retail apps is a joke, especially when things get volatile. I’ve been using Vale Vaultshire Trading
https://valevaultshire.org lately because the execution is crisp and the charting tools are actually institutional grade. It feels way more professional than the usual junk, and you don’t get all that unnecessary clutter slowing down your browser. It’s been my main choice for managing market swings lately because it just works when you need it most
