Fixes the TradingView live chart collapsing in the React app and adds a Hugging Face Spaces–friendly Streamlit entrypoint.
Changes:
- Adjust TradeView layout/CSS so the TradingView widget can reliably autosize to the available viewport height.
- Add a new
app.pyStreamlit multipage-style app (dashboard, analysis, screener, paper trading, about) intended for Hugging Face Spaces/local use. - Add a Python
requirements.txtfor the Streamlit app dependencies.

POPULAR_TICKERS is declared but not referenced anywhere in this Streamlit app. Consider removing it to avoid dead code, or wire it into a UI element (e.g., a selectbox/watchlist) so the constant has a purpose.

fetch_btn is created but never used, so the Analysis page always fetches data on every rerun and the button has no effect. Either remove the button or use it to gate the fetch (e.g., fetch only when clicked / persist the last result in session state).

The "Invested" metric is displaying total_current (current market value) rather than the actual amount invested (total_invested). This makes the Invested number inaccurate and also affects how users interpret P&L; consider showing cost basis for Invested and keeping current value as a separate metric/label.

The Paper Trading section description/PR notes mention realised P&L tracking, but the SELL path only adjusts quantity/cash and logs the trade—there’s no realised P&L calculation or accumulation (e.g., based on avg cost) stored in session state or shown in the UI. Either implement realised P&L tracking or update the feature description to match current behavior.

The screener loops over tickers and calls fetch_data() for each symbol individually. This is not a bulk fetch and can be slow / more likely to hit Yahoo Finance rate limits for larger lists; consider using yf.download() with a list of tickers (or batching) and then computing RSI/changes from the combined result.

There was a problem hiding this comment.
.tv-chart-container is now unused in the codebase (no references outside this stylesheet). Keeping it in this selector list can be misleading; consider removing it (or reintroducing the class on the TradeView container if you still want it as the primary hook).
| .tv-chart-container, |
The live TradingView chart rendered as a thin squashed strip with a large dark void below. Separately, no Streamlit entry point existed for the Hugging Face Space deployment.
Chart fix —
src/pages/TradeView.jsx+src/index.cssRoot cause:
min-h-screen(min-height: 100vh) on the flex column wrapper gave the browser no definite height to resolveflex-1against. TradingView'sautosizetherefore observed a near-zero container and collapsed the iframe.CSS updated to target the actual TradingView-injected DOM (

User: The app Looks like and template , modify overall app and fill all the details accordingly
Assistant: Which repo should I change and how do you want it filled in?
From your message I can use
Yuvi-070/FutureFlow(since you provided it), but I need a bit more direction on what “fill all the details accordingly” means so I don’t rewrite the wrong content.Please reply with:
If you say “Open a PR” and answer #1–3 (even roughly), I’ll update the whole template (copy, sections, and any placeholder assets) and wire up links so it feels like a finished app/site.
User: can you take a visit throughout the repo and each file to understand what it is exactly?
Assistant: I’ve kicked off a full walkthrough of the repository, and I’m currently waiting for your approval/response in the confirmation dialog before I can continue with the repo-wide scan and report back with what the app is and where each piece lives.
User: @copilot Accepted Confirmation: Are you sure?
Assistant: I’ve started a full repo-wide walkthrough to understand exactly what FutureFlow is, how it’s structured, and where the template/placeholder content lives. You can track progress here:
Once it finishes, I’ll come back with:
