Build a complete chart frontend with all modern platform features for tcharts.openalgo.theworkpc.com. The static HTML must be written to /home/ubuntu/charting-project/static/index.html.
The Rust backend is already running on port 5101 (proxied via nginx at https://tcharts.openalgo.theworkpc.com/api/). It already serves these endpoints:
- /api/symbols — list of 14 symbols with config
- /api/bricks/{SYMBOL} — pre-computed renko bricks (from symbols.yaml brick_size)
- /api/snapshots/{SYMBOL}?series=1 — indicator series (vidya, sma20, sma50, rsi, atr, macd, macd_signal, macd_hist, stoch_k, stoch_d, price) as time+value arrays
- /api/daily-values/{SYMBOL} — daily LIPI, 3-candle, bias values with today + last_completed
- /api/xover-events/{SYMBOL} — crossover events (BUY_CALL/BUY_PUT with sma2, vidya, price, brick_close)
- /api/daily-signal/{SYMBOL} — combined snapshot + xover latest
- /api/health — health check
The raw 5-min candle DBs are at /var/www/openalgo-chart/api/dbs/{symbol}_5min.db with table candles_5min(ts TEXT, open REAL, high REAL, low REAL, close REAL, volume INTEGER). The Rust server reads these directly.
REQUIREMENTS FOR THE FRONTEND:
1. CHART TYPE TOGGLE: Normal candles vs Renko bricks
- Candles mode: fetch raw 5-min OHLC from a new endpoint /api/candles/{SYMBOL}?interval={5m|15m|30m|1h|Daily}&days={N}
- Renko mode: fetch /api/bricks/{SYMBOL} (existing)
2. INTERVAL SELECTOR (for candle mode): 5m, 15m, 30m, 1h, Daily
- The Rust server aggregates 5-min candles to the requested interval
3. BRICK SIZE INPUT (for renko mode): numeric input, default from symbols.yaml
- Calls /api/bricks/{SYMBOL}?brick_size={N} — Rust recomputes renko on the fly
4. INDICATOR OVERLAYS with checkboxes (show/hide each):
- VIDYA (blue line)
- SMA20 (yellow line)
- SMA50 (purple line)
- LIPI (orange step line — daily value extends across each day's bars)
- 3-Candle (red dashed step line — daily value)
Each indicator must have a LABEL on the chart showing its current value (like RSI has its value labeled)
5. RSI SUB-PANEL below main chart:
- RSI 14 line with 30/50/70 grid lines
- Label showing current RSI value on the right side
6. MACD SUB-PANEL below RSI:
- MACD line, signal line, histogram bars
- Zero line grid
7. INFO PANEL: Price, VIDYA, SMA50, LIPI, 3-Candle, RSI, MACD, Stoch K — each with current value, color-coded bullish/bearish
8. XOVER EVENTS TABLE: last 10 crossover events with time, direction, SMA2, VIDYA, price, brick_close
9. AUTO-REFRESH every 5 minutes
10. SYMBOL SELECTOR: dropdown of all 14 symbols
11. LABEL EVERYTHING: Every indicator line on the chart must have a text label showing the indicator name and current value at the right edge of the line (like trading platforms do — "VIDYA 1040.95")
DESIGN: Dark theme (bg #0d1117, text #c9d1d9, green #3fb950, red #f85149). Monospace font. Canvas-based rendering. No external libraries.
IMPORTANT: This is a static HTML file only. No build step, no npm, no frameworks. Pure HTML/CSS/JS in one file. Write it to /home/ubuntu/charting-project/static/index.html.

ASSISTANT (hermes, glm-5.2)
Let me start by examining the existing file and testing the API endpoints to understand the data shapes.
All features are present — the original search just failed because `/` is a regex delimiter. Both the candles and bricks endpoints are properly referenced. The file is complete and being served correctly at https://tcharts.openalgo.theworkpc.com/.
## Summary
Built a complete chart frontend and wrote it to `/home/ubuntu/charting-project/static/index.html` (35,842 bytes, 879 lines). It's live at https://tcharts.openalgo.theworkpc.com/ (verified HTTP 200).
**What was built — all 11 requirements met:**
- **Chart type toggle** — Renko bricks vs Candles mode with button switcher; hides/shows relevant controls
- **Interval selector** — 5m/15m/30m/1h/Daily dropdown for candle mode, calls `/api/candles/{SYMBOL}?interval={X}&days={N}`
- **Brick size input** — numeric input, defaults from symbols.yaml per symbol, calls `/api/bricks/{SYMBOL}?brick_size={N}`
- **5 indicator overlays** with show/hide checkboxes:
- VIDYA (blue), SMA20 (yellow), SMA50 (purple) — line overlays with value labels at right edge
- LIPI (orange step line) — daily value extends across each day's bars
- 3-Candle (red dashed step line) — daily value
- Each has a **labeled current value at the right edge** (e.g. "VIDYA 1040.95")
- **RSI sub-panel** — RSI 14 line with 30/50/70 grid lines, overbought/oversold zones shaded, value label at right
- **MACD sub-panel** — MACD line (blue), signal line (pink), histogram bars (green/red), zero-line grid, both lines labeled at right edge
- **Info panel** — 12 indicators (Price, VIDYA, SMA20, SMA50, LIPI, 3-Candle, RSI, MACD, Stoch K, ATR, Signal, SMA2) with color-coded bullish/bearish values and contextual sub-text
- **Xover events table** — last 10 crossover events with time, direction, SMA2, VIDYA, price, brick_close
- **Auto-refresh** — every 5 minutes via `setInterval`
- **Symbol selector** — dropdown of all 14 symbols with exchange info
- **Everything labeled** — every indicator line has name + current value at the right edge of the chart
**Technical details:**
- Pure HTML/CSS/JS, no external libraries, no build step
- Dark theme (#0d1117 bg, #c9d1d9 text, #3fb950 green, #f85149 red), monospace font
- Canvas-based rendering with `devicePixelRatio` scaling for crisp display
- Responsive width, resize handler
- Binary-search time alignment between indicator series and bar timestamps
- Indicator series data is looked up per-bar by timestamp (handles different time arrays lengths)
