Service ops.\ntriggers:\n - tcharts\n - tcharts not updating\n - tcharts errors\n - charting-project\n---\n\n# TCharts Server Operations\n\nTCharts = Rust (axum + rusqlite) renko chart platform at\nhttps://tcharts.openalgo.theworkpc.com. systemd unit `tcharts.service`,\nport 5101. Single source file: `/home/ubuntu/charting-project/src/main.rs`\n(~1550 lines). Static frontend: `/home/ubuntu/charting-project/static/`\n(served by nginx directly; nginx proxies only `/api/` to 127.0.0.1:5101 with\n`proxy_read_timeout 30s`). Computed DBs live under\n`/home/ubuntu/charting-project/dbs/`.\n\nRelated: `tcharts-daily-indicator-overlay` skill for chart-UI work (daily\nlines, last-price legend, right-edge label queue — read before touching\n`static/index.html`; static edits go live without a restart, verify with\nmd5 served-vs-disk).\n\n## Architecture (REBUILT Aug 11, 2026 — incremental append + hot/cold tiers)\n\n- `#[tokio::main]` multi-thread. Boot: `fill_symbol()` for every symbol\n (~4s total — incremental), then `run_watcher()` every 60s via tokio::spawn.\n- **Incremental append**: `fill_symbol()` rebuilds bricks + indicators in\n memory from full history (fast, deterministic), then compares the DB tail\n (`MAX(brick_index)` + close). Match → INSERT only newer rows. Mismatch or\n empty table → DELETE + rebuild THAT INTERVAL only. Everything for one\n interval in ONE transaction. No global DELETEs — old rows never rewritten\n (raw 5-min candles are immutable, so bricks/snapshots are append-only).\n- **WAL mode + busy_timeout(15s)** on writer (fill_symbol) and readers\n (`open_computed`, `read_5min_db`) — API never blocks or sees partial data.\n- **Hot/cold tiers**: browser POSTs `/api/watch {\"symbol\":\"SBIN\"}` every 30s\n while the page is open. Watcher: HOT symbols (heartbeat < 3 min) recompute\n every cycle when the raw 5-min DB mtime is newer (>5s grace); COLD symbols\n only every 15th cycle. `ensure_fresh()` at the top of every computed-DB\n reader endpoint (`api_bricks/snapshots/daily_values/xover_events/\n daily_signal`) fills on-demand when stale (FILL_LOCK mutex + spawn_blocking)\n — first open of a cold symbol costs ~0.5-2s once, then it's hot.\n- **Incremental API**: `/api/bricks/<sym>?interval=5m&since=<brick_index>&\n limit=<N>` — `since` returns only newer bricks, `limit` returns last N;\n response includes `max_index`. Works on both the pre-computed path and the\n custom-brick_size on-the-fly path.\n- **Frontend**: initial load fetches `limit=max(2000, bars*2)` bricks (not\n full history — BANKNIFTY has 284k); then `refreshIncremental()` every 60s\n appends `since=<lastIdx>` + refreshes snapshot tail (limit=500) +\n daily-values ...

Works in Renko + Candles.\n2. **Last-price legend** — dashed horizontal line at the live last price\n (`snapData.latest.price`, falls back to last visible bar close) + a filled\n TradingView-style price box on the right axis (green/red vs previous bar\n close). Under the box: `HH:MM · Xm ago` last-candle timestamp + age,\n color-coded green ≤6m, orange ≤15m, red older.\n3. **Right-edge label queue** — ALL right-side labels (indicator values,\n daily lines, step lines, price box) are collected via\n `queueRight(y, text, color, opts)` in `drawChart()` and drawn by\n `resolveAndDrawRightLabels()` (sort + forward push-down + backward pull-up,\n per-label topPad/botPad). `opts.box=true` draws a filled tag; `opts.sub`\n adds a second caption line.\n\n## Pitfall — never draw right-edge labels inline\n\nThe `padR=140` right gutter is shared by every legend. Before the queue,\neach label did its own `fillText(W - padR + …)` and overlapped freely.\n**Any new right-side label MUST call `queueRight(...)`** — do not add inline\n`fillText` in the gutter, it will collide. `drawDailyStep()` takes an\noptional trailing `queue` arg for this.\n\n## Frontend edit workflow (no restart needed)\n\n1. Backup: `cp static/index.html static/index.html.bak.YYYYMMDD_<feature>`.\n2. Edit; keep using the `F(px)` font-scale helper (A−/A+ button) and the\n `C.*` color constants.\n3. Syntax check: extract the `<script>` block and `node --check` it (node is\n installed on the VPS).\n4. Verify live: `curl -s https://tcharts.openalgo.theworkpc.com/index.html | md5sum`\n must equal `md5sum static/index.html` — nginx serves the file directly,\n so a match means it's live; user hard-refreshes. No `systemctl restart`\n (the Rust binary is untouched by static edits).\n5. Coordinate system notes: `parseTs()` treats API `ts` strings as IST and\n returns a true UTC epoch, so `Date.now()/1000 - parseTs(ts)` is a correct\n age in seconds. Chart ...

Context: user said the\n3-day candle values on /finratio/ were \"very off\" and asked for a 15-min 3-candle\nline (weights 20/40/40). Reference: references/finratio-fork.md (fork overview),\nreferences/15m-interval-overlay.md (the tcharts 15m LIPI/RSI pattern this copies).\n\n## Part A — 3-Candle data verified EXACT (\"very off\" was NOT a data bug)\n\nAudit sequence — recompute independently BEFORE touching any code:\n\n1. Replicate the server exactly in Python from the raw 5-min DBs\n (`/var/www/openalgo-chart/api/dbs/<sym>_5min.db`, READ-ONLY):\n - pair 5m candles: for common timestamps, values = A_leg×lotA − B_leg×lotB per\n OHLC element (spread) or sum (sum mode); skip rows where any element is 0.0;\n high = max(four combined values), low = min(four combined values) — note the\n spread daily HIGH is max of combined OHLC spreads, NOT spread(maxA, minB).\n - daily OHLC: open = first 5m open, high = max, low = min, close = last 5m close.\n - 3-Candle for day D = 0.20·mean(D−2) + 0.40·mean(D−1) + 0.40·mean(D),\n mean = (O+H+L+C)/4. Newest day gets 40% together with D−1; D−2 gets 20%.\n This matches app.py `compute_3candle_from_5min` (the chart of record) 1:1 and\n Rust `compute_3candle_from_5min` (finratio main.rs ~line 746) 1:1. Verified\n against app.py source directly Aug 31.\n2. Diff against `/api/daily-values/<A-B>?mult=1&mode=<mode>` (raw values, mult=1).\n3. Result Aug 31: ALL 12 pairs × both modes, 2,932 rows, ZERO mismatches (±0.01\n rounding only). Stored `daily_values.three_candle` is exact. Verifier script\n kept at skill dir `scripts/check_all_pairs.py`.\n\n### Why it LOOKS off — explain to the user, do NOT \"fix\"\n1. TODAY's 3-Candle is computed off the still-forming daily candle → it moves with\n every 5-min candle all day and only settles at close. Two reads an hour apart\n legitimately differ.\n2. 60% of the weight sits on D−1 and D−2 → after a sharp trend day the line lags\n price BY DESIGN. HAL-DLF 08-26 example: day mean ≈8.2M while 3-Candle read\n ≈9.0M because 80% of the weight is the two older, higher days.\n3. It is a smoothed price, not a level tied to the day's range midpoint.\n\n### Raw-DB reading gotchas (each hit once in a session — cheap to avoid)\n- Raw 5-min DB filenames are LOWERCASE (`hal_5min.db`): passing \"HAL\" yields the\n misleading `sqlite3.OperationalError: unable to open database file`. Always\n `.lower()` the symbol.\n- Table name is `candles_5min` (NOT `candles`): `no such table: candles` on these\n DBs means wrong TABLE, not missing DB.\n- Lots: parse from the repo's OWN symbols.yaml; never hardcode (bi-monthly cron\n refresh drifts them).\n\n## Part B — 15m 3-Candle overlay (fron ...

So `nice_round(latest_close*0.01)` = `nice_round(−3011)` = **0.01**\n → 1-paisa Renko bricks on a ₹3-lakh series.\n2. `build_renko_bricks()` allocates EVERY brick in a Vec with no cap. Full history\n range ~₹274k / 0.01 = ~27 MILLION bricks in memory → **9.3 GB RSS** → kernel\n OOM-kills it.\n3. Boot path (\"recompute existing pairs\") + systemd `Restart=on-failure` (RestartSec=5)\n = crash loop: kill → restart → 9.3 GB again, every ~20s. The WHOLE VPS went into\n swap-thrash (load 29 on 6 cores, kswapd0 at 52% CPU) — user felt \"everything is slow,\n RAM 100%\". The OOM was global (no cgroup limit), so innocent services got squeezed.\n4. Diagnosis goldmine: `systemctl status finratio` prints\n `Consumed 14.79s CPU time, 9.3G memory peak` + `restart counter is at 16` —\n the smoking gun is IN THE UNIT STATUS, no dmesg spelunking needed.\n Kill the loop FIRST (`systemctl stop`) — box recovers instantly — then fix code.\n\n### Fixes applied (all in finratio-trade/src/main.rs + unit)\n- `pair_brick_size()`: compute from `latest_close.abs()` (SPREAD is legal-negative;\n brick size is a magnitude). ALSO its scale-floor check must use the abs base —\n `nice_round(neg*0.001)` is ALSO 0.01, so the first fix attempt alone re-accepted\n the poisoned stored value. Two places, same class of bug.\n- `build_renko_bricks()`: OOM guard — estimate `(hi−lo)/brick_size`; if > 2,000,000\n bricks, refuse BEFORE allocating (returns empty vec + `[renko] GUARD` log line).\n- `pair_brick_size()` meta floor: stored brick_size accepted on ...
