Covers data sourcing, backtest methodology, intraday whipsaw computation, and common pitfalls.\ntrigger: daily renko chart, VIDYA on daily, daily anchor, line in stone, renko vidya analysis, intraday whipsaw, ±0.5% skip zone\n---\n\n# Daily Renko + VIDYA Analysis Methodology\n\nAnalysis of daily Renko(2) charts with VIDYA-20 and SMA-2, using the \"Line in Stone\" approach for intraday signal validation.\n\n## Core Rules\n\n1. **DATA SOURCE**: Always use the **chart DB** (`/var/www/openalgo-chart/api/dbs/<symbol>_5min.db`) — this is NSE spot data, the same data `chart.openalgo.theworkpc.com` serves. Do NOT use the Morning Sniper DB (`/home/ubuntu/bots/morning_sniper/dbs/`) — that's NFO futures data with different prices. **The Daily VIDYA anchor must also read from the 5-min DB** (not daily aggregates from the chart API). Daily aggregates lose intraday reversals, producing different renko bricks (857 daily bricks vs 2714 5-min bricks for SBIN). The anchor now reads 5-min closes directly and builds renko with `Math.floor` start, matching the chart and bot exactly.\n\n2. **VIDYA IS LINE IN STONE**: Yesterday's VIDYA-20 value = today's FIXED horizontal anchor. It does NOT move during the trading day. When computing intraday whipsaws, VIDYA stays at yesterday's close-of-day value. The user WILL correct you if you show VIDYA as a rolling value.\n\n3. **SMA-2 is rolling**: SMA-2 on Renko bricks updates with each new 5-min brick. It crosses the fixed VIDYA line — that's the signal.\n\n4. **±0.5% Skip Zone**: If price is within ±0.5% of VIDYA anchor → HOLD existing position, DO NOT flip. This is the \"smoky day\" zone where SMA2 dances around VIDYA and whipsaws destroy profits.\n\n5. **15-pt Clearance Rule**: On intraday 5-min chart, only take entry when SMA2 is 15+ pts clear of VIDYA. This confirms direction on clear days and prevents premature entry on smoky days. Must be COMBINED with the ±0.5% zone rule.\n\n6. **Combined Rule for Carried Positions**:\n - Price > VIDYA + 0.5% AND SMA2 15+ pts above VIDYA → **GO LONG**\n - Price < VIDYA - 0.5% AND SMA2 15+ pts below VIDYA → **GO SHORT**\n - Price within VIDYA ± 0.5% → **HOLD existing position, no new entries, no flips**\n - On smoky days (price hugging VIDYA): **BOOK PROFIT, go flat, re-enter when direction is clear**\n\n7. **This is for OVERNIGHT positions, not intraday day-trading.** The user carries positions overnight. The analysis determines whether to hold, book out, or enter. Do NOT treat this as day-trading signals.\n\n## Backtest Results (INDIGO, Ja ... [35073 chars total, truncated]

You must get explicit approval before implementing.**\n\nWhen the user presents a topic, idea, or asks you to look at something, they want analysis and options — not code changes. Jumping to implementation without approval is the most common workflow violation.\n\n## When to Ask\n\nBefore you:\n- Edit any project file (code, config, data)\n- Create a new file\n- Run mutating terminal commands (install, deploy, restart services)\n- Make any irreversible change\n\n**STOP and ask**: \"Here's what I'd propose doing. Shall I go ahead?\"\n\n## Approval Signals\n\nOnly these count as approval to proceed:\n- \"Yes\" / \"Go ahead\" / \"Implement it\" / \"Do it\"\n- \"Let's do it\" / \"Proceed\" / \"Start\"\n- Clear directive like \"Change X to Y\"\n\n## NOT Approval Signals\n\nThese do NOT mean \"implement now\":\n- \"Let's move to point 4\" — discussing next topic, not authorizing changes\n- The user explaining what they want — they're still shaping the requirement\n- Silence after your analysis — they haven't said yes\n- Your own enthusiasm about a solution — excitement ≠ permission\n\n## What to Do Instead\n\n1. **Analyze** — read code, understand the problem, investigate\n2. **Present options** — lay out the approach with trade-offs\n3. **Wait for yes** — the user decides when to execute\n4. **Then implement** — once you have clear approval\n\n## Why This Matters\n\n- Premature implementation wastes time when the user is still deciding\n- Changes may conflict with the user's mental model if they haven't approved the approach\n- Reverting code changes is expensive (especially without git)\n- Discussion reveals requirements and edge cases before code is written\n\n## Example Violations\n\n❌ User: \"let's move to point 4\" → Agent immediately starts coding T4.1\n✅ User: \"let's move to point 4\" → Agent analyzes T4, presents plan, asks \"Want me to start on this?\"\n\n❌ User: \"tell me about pain point 4\" → Agent reads all files and patches 3 bots\n✅ User: \"tell me about pain point 4\" → Agent explains the situation and asks how to proceed\n\n## Plain-Language Clarification (non-developer users)\n\nWhen the user is a domain expert but NOT a developer (e.g. a trader dictating\nstrategies), clarifying questions must be phrased in their language, one ...

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 the daily-indicator\noverlay UI feature.\n\n## Architecture\n\n- `#[tokio::main]` multi-thread. On boot: `fill_symbol()` for every symbol in\n `load_symbols()` (CUPID excluded in the watcher), then a background\n `tokio::spawn` watcher runs `run_watcher()` every ~60s+compute-time.\n- `fill_symbol(sym)`: reads the raw 5-min DB (`/var/www/openalgo-chart/api/dbs/<sym>_5min.db`),\n then for each interval in [5m, 15m, 30m, 1h, 2h, Daily]: aggregates closes →\n floor-anchored renko bricks → VIDYA/indicators → writes into the symbol's\n computed DB (`renko_bricks`, `indicator_snapshots`, `xover_events` tables).\n- HTTP endpoints (`/api/symbols`, `/api/candles/<s>`, `/api/bricks/<s>`,\n `/api/snapshots/<s>`, `/api/daily-values/<s>`, `/api/xover-events/<s>`,\n `/api/daily-signal/<s>`, `/api/health`) are THIN READERS from the computed DBs.\n- Watcher logs `[watcher] OK <SYM>: bricks=... snap=...` per symbol and a DONE\n line per cycle in the journal. A full 13-symbol cycle takes ~50s.\n\n## Pitfall: NON-ATOMIC REBUILD STALLS THE API (diagnosed Aug 11, 2026)\n\nSymptom reported: \"frequent errors and not updating itself\" on the site.\n\nRoot cause: `fill_symbol()` does `DELETE FROM renko_bricks` / `indicator_snapshots`\n/ `xover_events` (autocommitted, OUTSIDE the insert transactions) and then\nre-inserts ~750k rows across per-interval transactions — in the SAME SQLite\nfiles the HTTP handlers read. Each cycle leaves every symbol's DB empty or\npartially rebuilt for a big slice of the ~50s rebuild window, every ~110s.\nVerified live: `/api/symbols` (trivial endpoint) stalled 45+s mid-cycle, fine\notherwise; nginx gives up at its 30s `proxy_read_timeout` → browser 504s and a\nfrozen chart. The watcher journal itself shows \"13 ok 0 failed\" throughout —\nthe pipeline is healthy; the serving layer is what breaks. Don't be fooled by\nclean watcher logs.\n\nFix (PROPOSED to user Aug 11, 2026 — confirm it was actually applied before\nrelying on it): (1) wrap each symbol's DELETE + all interval inserts in ONE\ntransaction so readers s ...
