Hi HN,

I built *StoxGPT*, a TradingView-powered chart where you control everything by chat. Example:

> *You*: add RSI > *Chart*: (RSI indicator appears) > *You*: change ticker to AMZN > *Chart*: (switches symbols)

No menus, no hotkeys—just natural language mapped to the TradingView JS API.

---

### Why? I got tired of drilling through panels to add indicators or tweak settings. A chatbot front-end felt faster, so I wired GPT-3.5-Turbo to TradingView’s `widget.activeChart()` calls.

---

### How it works * *React + Next.js* front-end * *Dummy OHLCV generator* (open-source) for this demo * Simple command grammar → LLM → function-calling layer → TradingView injection * Hosted on Vercel; cold start ~ 400 ms

---

### What I’m exploring next * *Plaid auth* → live Robinhood balances & fundamentals * Back-testing via OpenAI function calls * Sharing indicator “recipes” between users

---

### Looking for feedback * Would live data make this a daily driver? * Any killer feature missing? * Is the chat modality actually faster for you?

Thanks in advance—happy to answer anything!

Really interesting! The chat-command approach feels faster than hunting through indicator menus. When do you plan to add real time data (i.e. from Polygon as an example) Is your thought process to essentially use this for folks to learn (i.e. add MACD, EMA etc. and then have it explain them on live let's say 1 minute charts)? Also, curious how will the Plaid integration will work out, let's say to add your holdings from robinhood (or Schwab, etc.) - will it monitor, and/or interact with your holdings via chat/chart(s), etc?
