I now have the complete picture of the RATIO app. Let me check a few remaining details — active symbols, port availability, and what broker MCP is wired up.
All context gathered: 16 active symbols with lot sizes in yaml, port 5202 free, nginx pattern clear. One more check — verifying the Shoonya broker API returns lot sizes (since you said "rest of info from broker mcp"):
The broker quotes API doesn't return lot_size. Let me check how brick size and mult interact in the reference app — that's core to your "brick 2 plots" requirement:

- Reference app: /home/ubuntu/ratio-trade (Rust, port 5201), pair series = A/B component-wise, computed DBs per mode, mult = output-time scaling, UI sends brick size in display units
- symbols.yaml has all 16 active symbols with exact lot sizes (SBIN 750, DLF 950, INFY 400...)
- Shoonya quotes API verified live — it does NOT return lot_size (so lot info must come from yaml or search_scrip)

Only the formula was confirmed (ratio of notionals); the rest timed out so I'll proceed with the recommended defaults, which match your own saved-pair usage (all 4 saved pairs use mult=100 + brick 2 — so mult=100 default makes "brick 2" work immediately, exactly as you asked).

It belongs to the same category as Claude Code (Anthropic), Codex (OpenAI), and OpenClaw — autonomous coding and task-execution agents that use tool calling to interact with your system. Hermes works with any LLM provider (OpenRouter, Anthropic, OpenAI, DeepSeek, local models, and 15+ others) and runs on Linux, macOS, and WSL.\n\nWhat makes Hermes different:\n\n- **Self-improving through skills** — Hermes learns from experience by saving reusable procedures as skills. When it solves a complex problem, discovers a workflow, or gets corrected, it can persist that knowledge as a skill document that loads into future sessions. Skills accumulate over time, making the agent better at your specific tasks and environment.\n- **Persistent memory across sessions** — remembers who you are, your preferences, environment details, and lessons learned. Pluggable memory backends (built-in, Honcho, Mem0, and more) let you choose how memory works.\n- **Multi-platform gateway** — the same agent runs on Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, and 10+ other platforms with full tool access, not just chat.\n- **Provider-agnostic** — swap models and providers mid-workflow without changing anything else. Credential pools rotate across multiple API keys automatically.\n- **Profiles** — run multiple independent Hermes instances with isolated configs, sessions, skills, and memory.\n- **Extensible** — plugins, MCP servers, custom tools, webhook triggers, cron scheduling, and the full Python ecosystem.\n\nPeople use Hermes for software development, research, system administration, data analysis, content creation, home automation, and anything else that benefits from an AI agent with persistent context and full system access.\n\n**This skill helps you work with Hermes Agent effectively** — setting it up, configuring features, spawning additional agent instances, troubleshooting issues, finding the right commands and settings, and understanding how the system works when you need to extend or contribute to it.\n\n**Docs:** https://hermes-agent.nousresearch.com/docs/\n\n## Quick Start\n\n```bash\n# Install\ncurl -fsSL https://raw.githubuserco

The native MCP needs ~48s before retry. Meanwhile, I'll use the Flattrade and Kotak OpenAlgo REST APIs (their API keys are in config.yaml) to fetch the 5 missing futures lot sizes:
BANKNIFTY = 30 confirmed. But "LT" matched BOSCHLTD (substring trap) — rejecting that. Let me search precisely for LT, HPCL (NSE symbol HINDPETRO), and CUPID:

All 15 F&O symbols verified from broker MCP. Critically, the MCP shows 3 lot sizes CHANGED vs the old yaml — TCS 225 (yaml had 175), INDUSINDBK 700 (yaml 600), HPCL 2025 (yaml 1250), plus BANKNIFTY 30 (yaml 15). This is exactly why you want the MCP refresh. CUPID has no F&O contract → excluded.

The nginx change needs your approval — the command was blocked awaiting consent. Status so far:
**Built and verified locally:**
- /home/ubuntu/finratio-trade/ — Rust fork of ratio-trade, port 5202, compiled clean
- Formula verified EXACT: (priceA × lotA) / (priceB × lotB) — DLF-INFY = (676.15×950)/(1110.8×400) = 1.4456754 ✓
- Lot sizes MCP-verified from futures contracts (NFO/MCX): TCS 225, INDUSINDBK 700, HPCL 2025, BANKNIFTY 30, CRUDEOILM 10, LT 175, others unchanged; CUPID excluded (no F&O contract)
- Renko brick 2 plots correctly on the monetary ratio (bricks step in 2s: 134→132→134...)
- Own yaml (/home/ubuntu/finratio-trade/symbols.yaml) with verified lots, displayed in UI ("lot 950" next to dropdowns) and in chart legend (DLF×950 / INFY×400 ×100)
- All backends calculations in Rust; data from existing candle DBs; options trading surface stripped out
**Pending your OK (2 commands):**
1. Add nginx `/finratio/` → 127.0.0.1:5202 block to the tcharts vhost (backup saved at /tmp/tcharts.nginx.bak, new config tested-ready at /tmp/tcharts.nginx.new)
2. Install systemd service `finratio` and start it
**Also pending:** the bi-monthly cron job to re-verify lot sizes from broker MCP and update the yaml.
Say the word and I'll apply the nginx + systemd + cron steps.

Final check — confirming the existing /ratio/ app is untouched and both run side by side:
Done. FINRATIO is live at https://tcharts.openalgo.theworkpc.com/finratio/
**What was built** (all backend calc in Rust, same architecture as the reference):
1. **Monetary ratio** — (price A × lot A) ÷ (price B × lot B), component-wise on every 5-min bar, exactly as you specified. Verified to full precision: DLF-INFY = (676.15×950)/(1110.8×400) = 1.4456754 ✓. With mult=100 the chart reads ~144, and **renko brick 2 plots correctly** (verified on the public URL).
2. **Lot sizes from futures on the broker MCP** (NFO; MCX for CRUDEOILM) — and this surfaced real changes vs the old yaml: **TCS 225** (was 175), **INDUSINDBK 700** (was 600), **HPCL 2025** (trades as HINDPETRO; was 1250), **BANKNIFTY 30** (was 15). CUPID excluded — no F&O contract exists. Prices remain NSE equity candles from the existing DBs.
3. **Own yaml** at /home/ubuntu/finratio-trade/symbols.yaml (ratio-trade's yaml untouched), with lot sizes shown in the UI next to each dropdown ("lot 950") and in the chart legend (DLF×950 / INFY×400 ×100).
4. **Bi-monthly MCP refresh**: cron job `finratio-lot-refresh` (43d413490eab) runs the 1st of every 2nd month at 07:00 IST — script-only, no LLM. It re-verifies every lot from the brokers, and if anything changed it rewrites the yaml, deletes the stale computed DBs, and restarts the service. Tested end-to-end (planted a wrong lot → auto-corrected to 225 from broker).
5. **Clean separation**: port 5202, own DBs (`<a>_<b>_finratio_computed.db`), own saved_pairs.json, no options/trading surface, existing /ratio/ and tcharts untouched (all three verified 200).
One note: cron output from this session is local-only — check `cronjob list` after Sep 1 to see the refresh ran, or ask me to re-point its delivery to Telegram if you want it pushed to you.

Good catch — and there's a precise mathematical reason. Let me show you with live numbers from both apps:

2026-08-27 21:56
ASSISTANT (hermes, glm-5.3-flash)
It's not a bug — it's math, and your live numbers prove it perfectly:
**With fixed lot sizes, the monetary ratio is the price ratio × a constant:**
```
(A × lotA) / (B × lotB) = (lotA/lotB) × (A/B)
```
For DLF-INFY: lotA/lotB = 950/400 = **2.375**. And the actual chart data I just pulled:
| Date | /ratio/ close | /finratio/ close | ÷ |
|------|--------------|------------------|-------|
| Aug 26 | 60.0446 | 142.6060 | 2.375 |
| Aug 27 | 60.8705 | 144.5675 | 2.375 |
Every bar differs by *exactly* 2.375. Multiplying a whole series by a constant stretches the Y-axis but cannot change the shape — same swings, same renko turns, same indicator signals. So the charts are guaranteed identical while lots stay fixed. That's also why your x-factor (mult) never changes the picture — it's another constant.
**Where the monetary version actually differs from plain ratio:**
1. **When lots change.** Exchanges revise lot sizes — TCS went 175→225, INDUSINDBK 600→700, HPCL 1250→2025 just in this cycle. At each revision the constant changes, so the monetary series steps level while the plain price ratio doesn't. (Within each constant-lot regime the shape still matches the price ratio — nothing can change that.)
2. **The value has a meaning the price ratio doesn't:** 1.4457 = one DLF lot carries 1.45× the rupee exposure of one INFY lot. It's directly the **hedge ratio in lots** — long 1 DLF lot ≈ short 1.45 INFY lots for a rupee-neutral pair. The plain ratio 0.61 tells you nothing like that.
If you expected the two charts to *look* different day-to-day, the version that genuinely diverges from the price ratio is the **difference/spread** (notionalA − notionalB in rupees, P&L of holding 1 lot each) — the basket mode that already exists in the reference app. Say the word and I'll add it as a mode toggle on /finratio/ the same way.
2026-08-27 21:56
USER (hermes, glm-5.3-flash)
so my understanding - ratio chart is only price - sbin/dlf whatever the close on chart and divide it - whereas finratio is sbin close x lot / dlf close x lot - and bec lots are different - there would be diff mathamaticallu

ASSISTANT (hermes, glm-5.3-flash)
You've got both formulas exactly right. Let me pull SBIN-DLF live from both apps to show the one nuance:

2026-08-27 22:03
ASSISTANT (hermes, glm-5.3-flash)
Your formulas are both exactly right. But the conclusion needs one correction — **different lots change the numbers, not the shape:**
SBIN-DLF, same bar from both apps:
- ratio: (1042.90 / 676.15) = 1.5424 → ×100 = 154.24
- finratio: (1042.90×750) / (676.15×950) = 782,175 / 642,342 = 1.2177 → ×100 = 121.77
finratio/ratio = 121.77/154.24 = **0.78947 = 750/950 exactly**. Every bar on the chart differs by that same constant. Lots being different (750 ≠ 950) just scales the whole series down by 0.7895 — it stretches the Y-axis but doesn't bend the line. Same swings, same renko turns, same VIDYA crossovers. That's why the two charts look identical in shape.
So in plain terms:
- **ratio** = relative value of the two PRICES (0.79–1.54 territory)
- **finratio** = relative value of the two POSITIONS in rupees — 1.2177 literally means one SBIN lot carries 1.22× the rupee exposure of one DLF lot. It's your hedge ratio in lots, on the chart.
The only time finratio's math genuinely diverges from price-ratio over time is when an exchange changes a lot size (like TCS 175→225 recently) — the monetary level then steps to reflect the new exposure while the price ratio is blind to it.
If you want a chart that is mathematically a different animal day-to-day — not just rescaled — that's the **difference**: (A×lotA) − (B×lotB) in rupees, the actual P&L of holding 1 lot of each. Additive instead of multiplicative, so its shape really does differ from both. Want me to add it as a mode on /finratio/?
2026-08-27 22:03
USER (hermes, glm-5.3-flash)
additive or substraction chart would not help - bec in ratio i know when price goes below sma50 it is sell but in addition or substraction i would not know which to buy and which to sell - unless i say buy both when the chart is above sma 50
2026-08-27 22:07
ASSISTANT (hermes, glm-5.3-flash)
Exactly right — and you've hit the structural reason:
In a ratio, the **direction itself tells you the legs**. Ratio below SMA50 = A weakening against B → sell A, buy B (or swap the pair). Rising = the reverse. The numerator/denominator structure makes every signal a complete instruction: which to buy, which to sell, always.
In an additive/subtraction chart that information is gone. The line rising only tells you the *combination* moved up — it can't tell you whether A led, B led, or both rose together. "Chart above SMA50 → buy" only works as "buy both," and that's a different trade: it buys the strong leg and the weak leg alike. If A rallied because B collapsed, the additive chart can be rising while you'd be buying the very leg that's breaking down. The ratio never has that ambiguity — one series, two roles, numerator and denominator.
So: no change to the app. Your framework stays —
- **ratio / finratio** for the pair decision (above SMA50 = long A / short B, below = swap), finratio additionally telling you the rupee hedge ratio between the lots
- additive charts would only make sense as a "buy both / sell both" momentum rule, which is not the trade you're running — so I won't add the mode
/finratio/ stays as deployed: same decision logic as your ratio workflow, plus the lot-weighted hedge ratio on the Y-axis.

Confirmed: zero outbound HTTP in the Rust code — `reqwest` sits unused in Cargo.toml (a leftover from the stripped options module), all series data comes from the local 5-min candle DBs. I'll remove reqwest entirely so "no broker calls" is compile-verifiable.
One design note before I change the formula: the raw subtraction (A×lotA − B×lotB) is the rupee **gap** between the two positions' face values. For your SMA50 rule the chart works the same way — spread above its SMA50 = A-leg gaining ground in rupees. Building it now:
