Create /home/ubuntu/charting-project/static/options.html — an options charting page for the tcharts platform.
This page will be served at https://tcharts.openalgo.theworkpc.com/options (nginx serves static files from /home/ubuntu/charting-project/static/).
The page must:
1. Have a dark theme matching the existing tcharts index.html (same CSS variables, fonts, colors: bg #0d1117, panels #161b22, borders #30363d, text #c9d1d9, accent #58a6ff)
2. Top toolbar with 3 dropdowns in order: Stock (populated from /api/options/stocks), Offset (ATM/ITM1/OTM1), CE/PE (CE, PE)
3. A "Load Chart" button that calls POST /api/options/resolve with {symbol, offset, option_type} to resolve the NFO option symbol, backfill history, and compute renko bricks
4. A canvas-based renko chart that fetches /api/bricks/{option_symbol}?interval=5m and draws renko bricks (green up, red down)
5. Indicator overlays fetched from /api/snapshots/{option_symbol}?interval=5m — draw VIDYA(20) line and SMA(20) line on the chart, and RSI(14) in a sub-panel below
6. A live price legend showing current option symbol, LTP (from /api/options/quote), and indicator values
7. A "Watch" heartbeat — POST /api/options/watch {symbol: option_symbol} every 30s to keep the server filling live data
8. A refresh function that calls /api/bricks and /api/snapshots every 30s to get incremental updates
9. A trading panel below the chart with:
- Broker dropdown (from /api/options/brokers)
- Quantity input (default = lotsize from resolve response)
- BUY and SELL buttons (red/green)
- When clicked, POST /api/options/order {symbol, action, quantity, broker}
- Show order result (order ID, status, limit price)
10. A positions display that fetches /api/options/positions and shows current NFO positions
Use vanilla JavaScript (no frameworks). Use canvas for chart rendering. The chart should be similar in style to the existing index.html but simpler — just renko bricks + VIDYA + SMA + RSI sub-panel.
The API base URL is relative (same origin): /api/options/* and /api/bricks/* and /api/snapshots/*
Important: The page must be self-contained in one HTML file. No external dependencies. All CSS and JS inline.

Let me first examine the existing index.html for styling reference, then create the options.html file.

Now I have a thorough understanding of the existing index.html styling and conventions. Let me check the chart-data-api skill for the snapshots/bricks format to ensure I get the series structure right:

Verify the convention: first bar's open == daily\n candle's open (DLF Aug 18: 671.0 == 671.0).\n- **The 15:30 bar is an EOD SETTLEMENT bar**: carries the FULL day's volume and\n prints the daily close (daily close == its close; volume == day volume).

Intraday bars for cash end 15:30; the 15:40 F&O close appears in\n NFO series only.\n- **D candles skip weekends/holidays**: `days=3` may return only 2 rows (Aug\n 15/16 skipped).
