The dashboard itself looks cool.. I like TUI options myself, that said a lot of the crowd here are not into a lot of posts surrounding financial markets, in particular crypto or for that matter AI content, though I've relaxed a little and will just [AI] tag posts for AI generated tools/projects so long as they aren't generic "clone of X" type things.
Nice... worth noting, you should stick to compact line-delimited JSON when using this technique... I'd also look into websockets as another alternative, especially if you want bidirectional data streams.
Another consideration, you should use local storage and/or site messages to reduce the number of long lived, persistent connections to a single server, especially if your users are likely to have multiple tabs open to a website/app. Most browsers limit you to 6 simultaneous connections, so using the technique above without accounting for this behavior can cause issues with multiple open tabs.
For example, I'll assign a random id to the current browser/tab and then negotiate a "leader" as the active browser tab, or last active browser tab on activation, and that leader will be the one with the persistent connection, then updates can be fed into local-storage so the data/state can be used across multiple tabs. This can be used for things like notifications or interactive chats, such as on Facebook or LinkedIn.

Not really up for trying it currently... I really like the integrated terminal in VS Code, the "console" in CudaText doesn't seam nearly as good, also been using the DB tools in VS Code lately, which has been surprisingly useful.
Not to mention, I use Code's C@ extensions a lot as well, which likely won't see an equivalent here. I also use Rider when more actively working on a C# project, depending on what I'm doing... but mostly Code.
