USER (hermes, kimi-k3)
so i want to compare two stocks - which are from F&O space - one will be long and other will be short - we will look for last 6 minths data and find out what their ratio is saying - we will plot that ratio as any other stock gets plotted in chart - both normal candle and renko - we will plot all the indicators like we have our repo tcharts - we have created seperate folder so that we can have seperetae api for the trading pair - any question - i would like to first use the universe of 15 stocks which we have
2026-08-19 18:04
ASSISTANT (hermes, kimi-k3)
Got the concept. A few questions before I start:
1. Ratio definition: simple close_A / close_B? And the numerator is always the LONG leg, denominator the SHORT leg — correct?
2. Data source: I'll pull the 6-month daily data from your existing pipeline DBs (the same ones tcharts uses). Where is the 15-stock universe list — the screener symbols?
3. Stack: separate folder + separate API, but same look as tcharts. Do you want me to reuse the Python lightweight-charts version (chart.openalgo style) as the base, since it's easiest to extend — or the Rust canvas one?
4. Renko on ratio: ratio values are small (e.g. 2.34), so brick size should be auto (% of ratio, like 1%) or a fixed input you set per pair?
5. Indicators: full set like tcharts (VIDYA, LIPI, RSI etc.) computed ON the ratio series itself — right?

USER (hermes, kimi-k3)
1. not necessary - it can be both - depends upon what ratio chart is saying - if it is falling then it wpuld be opposite 2. yes we will not use any new broker calls - our db will be calculation everything from the db we have - in case we have some other stock we will first make it pary of our main yaml (tcharts ) and then pull the data 3. we will use ditto tcharts - i tried making same project with options - but the chart and functionality differs - so request is to keep the same look and feel and functions as rust tcharts 4. we can give user the option to multiply with factor - it could be 60 or 100 or 150 or 200 depending upon how easier it is to plot on charts - but the ratio remains the same 5. yes - it would be easy to manage with old sets
2026-08-19 18:09
ASSISTANT (hermes, kimi-k3)
Clear. So the plan is: clone the Rust tcharts codebase as the base (identical look/feel), add a pair/ratio layer that computes everything from the existing DBs, with a user-set multiplier for plotting.
First step: let me inspect the existing Rust tcharts code and data layout so the plan is concrete.

I've mapped the existing setup. Here's what I found:
1. Rust tcharts (charting-project) reads raw 5-min DBs at /var/www/openalgo-chart/api/dbs/<sym>_5min.db, computes indicators into <sym>_computed.db, serves JSON via axum. Daily candles are aggregated from the 5-min ones.
2. Data depth is fine: SBIN raw DB goes 2026-01-01 → today, so 6 months of daily ratio is covered for all symbols.
3. Ratio approach fits cleanly: rattio-trade will be a copy of this same Rust app, but its candle layer will compute ratio OHLC = (A.ohlc / B.ohlc) × multiplier, aligned by timestamp/date, then run the SAME indicator pipeline (VIDYA, LIPI, RSI, Renko etc.) on that series. No new broker calls.
ONE issue before we proceed:
4. The universe: symbols.yaml has 11 symbols (SBIN, INDIGO, HAL, TCS, ULTRACEMCO, LT, DLF, INFY, INDUSINDBK, ASHOKLEY, BIOCON) — not 15. Which 4 are missing? Or should we start with these 11?

Here's the plan I'd propose:
1. rattio-trade will be a copy of the charting-project Rust app — same UI, same indicators, same Renko — but as its own service on its own port (separate API for pairs).
2. It will read the SAME symbols.yaml that tcharts uses (/var/www/openalgo-chart/api/symbols.yaml). When you add a symbol there and its data gets filled, it automatically becomes available for pairing here. No separate yaml to maintain.
3. New pair layer: you pick Stock A and Stock B from the 11 symbols, plus a multiplier (60/100/150/200 — editable). Ratio candles = A price ÷ B price × multiplier, built by aligning both stocks' candles on the same timestamps. Works for both normal candles and Renko, since both are derived from the same ratio series.
4. All existing indicators (VIDYA, LIPI, RSI, MACD, Stoch, ATR, SMAs, 3-candle) run unchanged ON the ratio series.
5. Computed ratio data gets its own DBs inside rattio-trade/dbs (e.g. sbin_infy_ratio.db) — nothing written back to the tcharts DBs.
Shall I go ahead and build it?

(4) Boot: recompute only pairs that already have a computed DB in rattio dbs/; do NOT compute the plain yaml symbols. (5) Add `mult` query param (float, default 100.0) to /api/candles/{symbol} and /api/bricks/{symbol}: pair-only, output-time scaling of OHLC and price-like series (vidya, sma20, sma50, atr, macd, macd_sig, macd_hist, lipi, three_candle, brick OHLC); NEVER scale rsi/stoch_k/stoch_d; no recompute on mult change.

Everything checks out. One nice surprise: the shared yaml actually has 15 symbols (SBIN, INDIGO, HAL, TCS, ULTRACEMCO, LT, DLF, INFY, INDUSINDBK, ASHOKLEY, BIOCON, BANKNIFTY, CUPID, TATASTEEL, CRUDEOILM) — your "universe of 15" was right; I had earlier looked at a stale copy. All 15 are pairable.
Status:
1. rattio-trade is built and running on port 5201. Pair API verified end-to-end: SBIN-INFY daily candles (121 days), Renko bricks, all indicators (VIDYA/LIPI/RSI/MACD/Stoch/ATR/SMAs) on the ratio, mult scaling exact (0.9364 x100 = 93.64), mult=1 returns raw ratio. Watch/freshness works for pairs.
2. UI is the same tcharts page + Stock A / Stock B dropdowns, swap button, multiplier (60/100/150/200). URL params work: ?symbol=SBIN-INFY&mult=100&interval=D&chartType=renko
3. Fixed one real bug along the way: ratio candles can get wick/body inversions (A and B print extremes at different moments) — high/low are now re-bracketed, 0 invalid candles.
ONE decision left:
4. Right now the server is a temporary process under my session — it dies when I exit. Deployment drafts are ready in rattio-trade/nginx/ (systemd unit + nginx vhost for rattio.openalgo.theworkpc.com). Shall I install them (systemd enable + nginx + certbot for HTTPS)?

--- ✗ TASK 1/2: Implement the BACKEND of rattio-trade per /home/ubuntu/rattio-trade/PAIR_API.md in /home/ubuntu/rattio-trade/src/main.rs (+ Cargo.toml). Work items: (1) Cargo.toml: rename package and bin to 'rattio', add tower-http 'fs' feature. (2) Change HTTP_PORT to 5201 and COMPUTED_DB_DIR to /home/ubuntu/rattio-trade/dbs; keep CHART_DBS_DIR and the yaml path unchanged (shared, read-only). (3) Implement virtual pair symbols 'A-B' exactly per contract: pair detection, ratio raw-candle generation by inner-joining the two raw 5-min DBs on ts (component-wise A/B, volume 0, UNSCALED), pair computed DB dbs/<a>_<b>_ratio_computed.db with identical schema, default pair Renko brick = nice_round(latest ratio close * 0.01) stored in a meta table at first fill and reused, pair VIDYA period 20 smooth 0.2, freshness check against BOTH raw DB mtimes, /api/watch accepting pair symbols. (4) Boot: recompute only pairs that already have a computed DB in rattio dbs/; do NOT compute the plain yaml symbols. (5) Add `mult` query param (float, default 100.0) to /api/candles/{symbol} and /api/bricks/{symbol}: pair-only, output-time scaling of OHLC and price-like series (vidya, sma20, sma50, atr, macd, macd_sig, macd_hist, lipi, three_candle, brick OHLC); NEVER scale rsi/stoch_k/stoch_d; no recompute on mult change. (6) Make all existing endpoints accept pair symbols where meaningful (snapshots, daily-values, developing-daily, xover-events, daily-signal). (7) Add a ServeDir fallback serving /home/ubuntu/rattio-trade/static so the UI loads directly from http://<host>:5201/ without nginx. (8) Build with: cd /home/ubuntu/rattio-trade && cargo build --release 2>&1 — the target/ dir was copied from charting-project so deps are warm; iterate until it compiles with zero errors. Then run the binary briefly (timeout 30s, background) and verify with curl: /api/health returns success; /api/candles/SBIN-INFY?interval=D&days=180&indicators=1&mult=100 returns non-empty candles with indicator values around ~50-60 (SBIN/INFY ratio is ~0.55, x100); /api/candles/SBIN-INFY?interval=D&mult=1 returns values ~0.55 for the same timestamps (proving mult is pure scaling); /api/bricks/SBIN-INFY?mult=100 returns renko bricks. Report actual curl result excerpts. (status=timeout, api_calls=35, 600.0s) ---
(no summary — status=timeout: Subagent timed out after 600.0s with 35 API call(s) completed — likely stuck on a slow API call, tool call, or unresponsive network request.)

--- ✓ TASK 2/2: Implement the FRONTEND of rattio-trade by editing ONLY /home/ubuntu/rattio-trade/static/index.html (keep a backup copy index.html.orig first). Requirements: (1) IDENTICAL look, feel, layout, CSS, and chart behavior to the current tcharts page — the user rejected a previous project for diverging, so change as little as possible. (2) In the existing control bar (wherever the symbol selector lives), replace/augment the single symbol picker with: Stock A dropdown, Stock B dropdown (both populated from GET /api/symbols, which returns {status:'success',symbols:[{name,...}]}), a swap button that exchanges A and B, and a multiplier input (number, default 100; provide quick choices 60/100/150/200 e.g. via datalist). (3) Whenever a pair is selected, the frontend uses symbol 'A-B' in ALL existing API calls (candles, bricks, watch, snapshots, etc.) and appends &mult=<value> to the candles and bricks fetches; changing A, B, or mult refetches/redraws using the same existing code paths. (4) URL params must work: ?symbol=SBIN-INFY&mult=100&interval=D&chartType=renko — keep existing symbol/interval/chartType handling, add mult; when symbol contains '-', pre-fill the A/B dropdowns by splitting on '-'. (5) Chart title/legend shows 'SBIN/INFY x100' style label. (6) Guard: if A==B show a small inline warning and don't fetch. Verify by serving the static dir locally (e.g. python3 -m http.server in static/) and confirming the page loads without JS console syntax errors (you can use node --check on extracted JS if easier, or just careful review). You cannot test the live API (backend is being built separately) — just ensure the fetch URLs are constructed exactly as specified. Report what you changed.

Changing A, B (onPairChange) or mult (onMultChange) refetches via existing code paths; swapPair() exchanges A and B.

ASSISTANT (hermes, kimi-k3)
Both agent results are in — nothing new to act on: the frontend agent completed cleanly, and the backend agent's timeout was already covered by me directly (build, OHLC fix, and full verification done above).
So rattio-trade is complete and running on :5201. The only open item is the deployment question from my last message: install systemd + nginx + certbot for rattio.openalgo.theworkpc.com — yes or no?
2026-08-19 18:41
USER (hermes, kimi-k3)
https://tcharts.openalgo.theworkpc.com/ratio - can we do that - or another cerbot - if yes then change to ratio not rattion
2026-08-19 19:01
ASSISTANT (hermes, kimi-k3)
Yes — mounting under the existing tcharts domain at /ratio works and needs NO new certbot (the existing cert already covers tcharts.openalgo.theworkpc.com). One small code tweak is needed: the page's API calls must go to /ratio/api/ so nginx forwards them to the ratio backend instead of the tcharts one.
Doing the rename to "ratio" + the mount now. First, checking how the page builds its API URLs.

Done. Summary:
1. Live URL: https://tcharts.openalgo.theworkpc.com/ratio/?symbol=SBIN-INFY&mult=100&interval=D — no new certbot needed, mounted on the existing tcharts domain.
2. Renamed everything to "ratio": folder /home/ubuntu/ratio-trade, binary ratio, systemd service ratio (enabled, auto-restarts, currently active).
3. Verified through the public URL: page loads (200), /ratio/api/health OK, SBIN-INFY daily candles 121 bars with correct ratio values. Renko + all indicators working; A==B guard, swap button, and mult param all in place.
4. Housekeeping: fixed an nginx conflict (my backup file was inside sites-enabled — moved to /home/ubuntu/vps_backup/), and nginx reloaded clean.
Open it and play with a few pairs — SBIN-INFY, HAL-DLF, TCS-INFY are interesting ones. If the chart render looks off anywhere, tell me what you see.

That's the Fill Data button — on the ratio page it still calls the tcharts Flask broker-fill endpoint, which doesn't know pair symbols like SBIN-INFY, so no status shows. For pairs it should refresh from the raw DBs instead (no broker call). Fixing it.

Fixed. The Fill Data button now works on the ratio page:
1. For pairs it calls the ratio backend (POST /ratio/api/fill/SBIN-INFY) which recomputes from the existing raw DBs — no broker call. You'll now see "Fill: already up to date (364 bricks, latest ...)" or "Fill: updated (...)".
2. Verified live: SBIN-INFY → up_to_date (364 bricks); HAL-DLF (a pair never opened before) → updated (954 bricks) — so the button also builds brand-new pairs on demand.
Refresh the page and try it.

Renko 1-brick bug: the brick size you type (0.5/1/2) is in displayed (x100) units, but the backend was building bricks with it on the unscaled ratio (~0.20) — so 0.5 meant "ratio must move 0.5", impossible, hence 1 brick. Fixed: backend now converts to unscaled before building. Verified: SBIN-INDIGO Daily gives 47 bricks at 0.5, 13 at 1, 7 at 2.
2. Crosshair now shows both stock prices at the hovered candle — e.g. "SBIN 1048.60 INDIGO 5241.00" (blue = A leg, orange = B leg), right under the ratio OHLC line. Works in both candle and Renko mode.

few asks - 1. when changing the multiplier - the indicators are stillplottin x1 2.please check crosshair not getting the values of shares - 3.

Three separate issues. Let me check each properly — first, where the indicator overlays actually come from (I suspect the snapshots endpoint doesn't take mult).

Indicators now scale correctly (price 94, VIDYA 92.7 scaled; RSI 64.3 unscaled). Testing the saved-pairs store.

All three are done and verified:
1. Indicators with multiplier: the overlays were coming from the snapshots/daily-values endpoints which ignored mult — that's why they plotted at x1. Fixed backend + frontend: VIDYA/SMA/ATR/MACD/LIPI/3C now scale with mult, RSI/Stoch correctly stay 0-100. Verified: price 94, VIDYA 92.7, RSI 64.3.
2. Crosshair leg prices: the code was correct, but you were very likely seeing a cached old page — the /ratio/ proxy had no cache headers. Added no-store in nginx, plus made the leg line always render (shows — if a leg has no bar at that exact timestamp). Do one hard refresh (Ctrl+Shift+R) and it should be there.
3. Saved pairs: new "Saved" control group in the bar — dropdown + Save + ✕. Save captures EVERYTHING: A, B, mult, interval, Renko/candles mode, brick size, days, bars, and all 9 indicator checkboxes. Stored server-side (saved_pairs.json), so it's the same from any browser. Selecting one restores the exact visual. Also works as a URL: ?saved=SBIN-INFY swing — handy for bookmarking a trade idea. CRUD verified end-to-end.
Hard-refresh once and try: change mult to 150 (indicators should follow), hover a candle (both stock prices), then Save your pair.

one more ask - i want the hyperlink for my calculations pertaining to ratio pair - for example i am looking at sbin indigo pair right now - i look at one candle - example Mar 3 abnd comparing it to any other particular day candle - i need that in that i should give buy/sell (buy-num long -den short) once it has days - it calculates - script closing for both days - multiply with lot size and gives me the inr p&L as compared to both day 1 to day 2 - may be one popup on chart which does all the calculation once it knows pair(from the chart which is opened) - long /short and day1 to day 2
2026-08-19 20:24
ASSISTANT (hermes, kimi-k3)
Good ask — a pair P&L calculator pinned to the chart, with a shareable link. Plan: a Calc popup on the chart (pair auto-taken from what's open, pick Day 1 / Day 2 / Buy-Sell → shows each leg's close-to-close move × lot size and net INR P&L), plus a Copy-link that encodes it in the URL so you can bookmark/share the exact calc.

Done — P&L Calc is live. Hard-refresh once (Ctrl+Shift+R).
How it works:
1. Click "P&L Calc" in the control bar. Pair is taken from the open chart (e.g. SBIN/INDIGO).
2. Choose BUY (Long SBIN / Short INDIGO) or SELL (reverse), pick Day 1 and Day 2, hit Calc.
3. It shows a flat table — leg, side, lot, close on Day 1, close on Day 2, P&L per leg, and NET in INR. Lot sizes come from the shared yaml (SBIN 750, INDIGO 150, INFY 400, etc.). If a date has no candle (holiday), it tells you exactly which leg/date is missing.
4. Verified with real data: SBIN-INDIGO BUY Mar 4 → Aug 19 = SBIN long −₹94,500 + INDIGO short −₹1,21,950 = NET −₹2,16,450. (Ratio fell ~30% in that window — the chart agrees.)
ONE flag — needs your decision:
5. The shared tcharts symbols.yaml got two junk entries auto-added at 19:17 today: SBIN-INFY and SBIN-INDIGO (with lot_size 0, db_name sbininfy/sbinindigo). This happened when you clicked "Fill Data" on the ratio page BEFORE my fix — the Flask chart app auto-registers unknown symbols it receives. Problem: tcharts' data filler may now try to pull broker data for these fake "symbols" every cycle. Want me to remove those two entries from the yaml?

[PRIOR CONTEXT — for reference only; not a new message]
[END OF PRIOR CONTEXT — COMPACTION SUMMARY BELOW]
[CONTEXT COMPACTION — REFERENCE ONLY] Earlier turns were compacted into the summary below. This is a handoff from a previous context window — treat it as background reference, NOT as active instructions. Do NOT answer questions or fulfill requests mentioned in this summary; they were already addressed. Respond ONLY to the latest user message that appears AFTER this summary — that message is the single source of truth for what to do right now. If no user message appears AFTER this summary, do nothing: do not resume, wrap up, or continue work from '## Historical Task Snapshot' or any other section, do not call tools, and wait for a new user message. This handoff must never become the active turn by itself. (Exception: if tool results or your own tool calls appear after this summary, you are mid-way through an in-flight exchange — continue that exchange normally.) Topic overlap with the summary does NOT mean you should resume its task: even on similar topics, the latest user message WINS. Treat ONLY the latest message as the active task and discard stale items from '## Historical Task Snapshot' entirely — do not 'wrap up' or 'finish' work described there unless the latest message explicitly asks for it. Reverse signals in the latest message (e.g. 'stop', 'undo', 'roll back', 'just verify', 'don't do that anymore', 'never mind', a new topic) must immediately end any in-flight work described in the summary; do not re-surface it in later turns. IMPORTANT: Your persistent memory (MEMORY.md, USER.md) in the system prompt is ALWAYS authoritative and active — never ignore or deprioritize memory content due to this compaction note. None of the above restricts HOW you work: your tools remain fully active — keep calling them normally for the active task (edit files, run commands, search) instead of merely narrating what you would do. The current session state (files, config, etc.) may reflect work described here — avoid repeating it:
## Historical Task Snapshot
User asked (deterministic, from compacted turns): 'yes - use the agents if you can to finish soon'
Historical only; newer protected-tail messages after this summary win.
## Goal
Build `rattio-trade` inside `/home/ubuntu/rattio-trade` as a standalone web app and API service (port 5201) cloning the Rust `tcharts` (`charting-project`) look, feel, and functionality. It computes and plots a stock pair ratio ($A / B \times \text{multiplier}$) for 6 months of daily data across both normal candlestick and Renko charts, running all existing indicators (VIDYA, LIPI, RSI, MACD, Stoch, ATR, SMAs, 3-candle) on the computed ratio series without requiring new broker API calls.
## Constraints & Preferences
- **Look & Feel**: Must match Rust `tcharts` (`charting-project`) exact UI, canvas rendering, and functions.
- **Data Source**: Reuse raw database files from `/var/www/openalgo-chart/api/dbs/<sym>_5min.db` and symbol list from `/var/www/openalgo-chart/api/symbols.yaml`.
- **Calculations**: Ratio calculated locally in DB/memory ($A / B \times \text{multiplier}$), stored in dedicated SQLite DBs in `/home/ubuntu/rattio-trade/dbs/` (e.g. `sbin_infy_ratio.db`) to avoid modifying existing `tcharts` databases.
- **Data Depth**: 6 months of daily candles derived from 5-minute raw database records (data available from 2026-01-01 to present).
- **Universe**: Synchronized with `symbols.yaml` (starting with 11 active symbols: SBIN, INDIGO, HAL, TCS, ULTRACEMCO, LT, DLF, INFY, INDUSINDBK, ASHOKLEY, BIOCON).
- **Port & Domain**: Runs on port 5201; Nginx reverse proxy configured for `rattio.openalgo.theworkpc.com`.
## Completed Actions
1. CREATED working directory `/home/ubuntu/rattio-trade` on 2026-08-19 [tool: terminal]
2. INSPECTED symbol definitions in `/var/www/openalgo-chart/api/symbols.yaml` and SQLite schema in `/var/www/openalgo-chart/api/dbs/sbin_5min.db` on 2026-08-19 [tool: terminal]
3. COPIED base Rust codebase, `Cargo.toml`, `Cargo.lock`, `target/` directory, static files, and source files from `/home/ubuntu/charting-project/` to `/home/ubuntu/rattio-trade/` on 2026-08-19 [tool: terminal]
4. WRITTEN API specification document `/home/ubuntu/rattio-trade/PAIR_API.md` defining endpoints (`/api/health`, `/api/symbols`, `/api/pair/candles`, `/api/pair/renko`) on 2026-08-19 [tool: write_file]
5. DELEGATED parallel subagent tasks (ID `deleg_62bc9b79`) for backend implementation (`src/main.rs`) and frontend adaptation (`static/index.html`) on 2026-08-19 [tool: delegate_task]
6. CREATED Nginx config `/home/ubuntu/rattio-trade/nginx/rattio.openalgo.theworkpc.com` and systemd unit `/home/ubuntu/rattio-trade/nginx/rattio.service` on 2026-08-19 [tool: write_file]
7. CREATED project documentation `/home/ubuntu/rattio-trade/README.md` on 2026-08-19 [tool: write_file]
## Active State
- **Working Directory**: `/home/ubuntu/rattio-trade`
- **Subagents**: Task group `deleg_62bc9b79` running (Task 0: Backend Rust modifications in `src/main.rs`; Task 1: Frontend canvas UI modifications in `static/index.html`).
- **Files Created**:
- `/home/ubuntu/rattio-trade/PAIR_API.md`
- `/home/ubuntu/rattio-trade/nginx/rattio.openalgo.theworkpc.com`
- `/home/ubuntu/rattio-trade/nginx/rattio.service`
- `/home/ubuntu/rattio-trade/README.md`
- **Port Allocation**: Port 5201 designated for `rattio` binary execution.
## Blocked
None.
## Key Decisions
- **Architecture**: Separate folder and standalone binary (`rattio`) running on port 5201 to keep pair API completely decoupled from single-stock `tcharts`.
- **Database Sharing**: Read-only access to existing `/var/www/openalgo-chart/api/dbs/*` 5-minute candle databases to generate pair ratios without duplicative data ingestion or external broker API calls.
- **Multiplier Logic**: Plotted series uses editable user multiplier (60, 100, 150, 200, or custom) to scale low decimal ratios ($A / B$) into chart-friendly price ranges.
## Errors & Fixes
- `grep` exit code 2 when searching non-existent directory `/home/ubuntu/rust-screener` on 2026-08-19. Resolved by locating actual data source at `/var/www/openalgo-chart/api/dbs/`.
## Resolved Questions
- *Ratio definition*: Numerator and denominator direction depends on trend analysis; user can set stock A, stock B, and plot multiplier.
- *Data source*: Pulled directly from existing SQLite databases in `/var/www/openalgo-chart/api/dbs/`.
- *UI Base*: Rust Axum + HTML5 Canvas (`charting-project` look and feel).
- *Symbol universe*: Using 11 active symbols from `/var/www/openalgo-chart/api/symbols.yaml`.
## Relevant Files
- `/home/ubuntu/rattio-trade/PAIR_API.md`: API spec contract for pair endpoints.
- `/home/ubuntu/rattio-trade/src/main.rs`: Axum web backend and calculation engine.
- `/home/ubuntu/rattio-trade/static/index.html`: Canvas rendering UI for candlestick, Renko, and indicators.
- `/var/www/openalgo-chart/api/symbols.yaml`: Shared active symbol list.
- `/home/ubuntu/rattio-trade/nginx/rattio.openalgo.theworkpc.com`: Nginx vhost proxy configuration.
- `/home/ubuntu/rattio-trade/nginx/rattio.service`: Systemd service definition.
## Critical Context
- Database location: `/var/www/openalgo-chart/api/dbs/<symbol>_5min.db`
- `rattio` API service runs locally on `http://127.0.0.1:5201`
- Computed ratio SQLite DBs output to `/home/ubuntu/rattio-trade/dbs/`

--- END OF CONTEXT SUMMARY — respond to the message below, not the summary above ---
The junk entries also created junk DB files (`sbinindigo_5min.db`, `sbininfy_5min.db`) in the shared raw dbs dir. Let me check what's in them before removing.
The real SBIN DB appears empty of tables. Let me check how the ratio app's raw DB path function is defined and what the real chart DB actually looks like.
The uppercase `SBIN_5min.db` and `INDIGO_5min.db` are 0-byte empty files (junk from the broken fill). The real data must be lowercase. Let me check `safe_name` and the lowercase DBs.
Real data lives in lowercase `sbin_5min.db`/`indigo_5min.db`. The two junk entries (SBIN-INFY, SBIN-INDIGO) pollute the ratio symbol dropdowns too. Removing them plus the two junk DBs.

All done. Summary:
1. P&L Calc is live on the public page (verified: calc button + popup code served, 8 references present; pair chart still returns 121 daily candles at mult 100).
2. Cleaned the shared symbols.yaml — removed the two junk entries SBIN-INFY and SBIN-INDIGO that got auto-registered when the old broken Fill Data called the Flask chart API. The 15 real symbols are intact.
3. Deleted the two junk raw DBs (sbininfy_5min.db, sbinindigo_5min.db). Restarted the ratio service; dropdowns now show 15 clean symbols, no pair junk.
Hard-refresh (Ctrl+Shift+R) the page and use P&L Calc on any pair: BUY/SELL side, Day 1/Day 2, hit Calc → per-leg close-to-close × lot + NET INR. If a date has no candle it tells you exactly which leg/date to fix.

Backfill complete: 155 days fetched, 11,625 rows, range 2026-01-01 to 2026-08-19. The 10 "no data" days are all Indian market holidays (Jan 15 Pongal, Jan 26 Republic Day, Mar 3, Mar 26, Mar 31, Apr 3, Apr 14, May 1, May 28, Jun 26) — correct, not errors.
Now let me verify the data is usable — check the DB and confirm the ratio service can read it.
HPCL-INFY pair works end-to-end. Let me verify the public URL serves it too.

Done. HPCL is fully live.
1. Added HPCL to the shared symbols.yaml (NSE, brick 2, lot_size 1250, db_name hpcl) — it now appears in tcharts, the ratio app, and the screener automatically.
2. Backfilled 5-min candles from Jan 1, 2026 into hpcl_5min.db: 155 trading days, 11,625 rows, range 2026-01-01 → 2026-08-19. The 10 skipped days are all Indian market holidays (Jan 15, Jan 26, Mar 3, Mar 26, Mar 31, Apr 3, Apr 14, May 1, May 28, Jun 26) — correct.
3. Verified end-to-end: HPCL-INFY pair builds and serves 121 daily candles through the public URL (last close 32.72 at mult 100).
One note on the symbol: the broker's trading symbol for HPCL is HINDPETRO (not HPCL), so the backfill fetched HINDPETRO data into the hpcl DB. The yaml name stays HPCL for display, which is what you wanted. The ratio app reads the hpcl_5min.db directly, so it all lines up.
The backfill script is saved at /home/ubuntu/ratio-trade/backfill_hpcl.py if you ever need to re-run or extend it.
