Computes a grouped numeric summary and numeric row ordering for up to 200 trading journal observation records (entry_price, exit_price) using local analytical engines — no live data or external lookups.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability trading-journal-observations-grouped-numeric-summary-numeric-row-9336684b -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and row ranking on my trading journal entries? I have 4 trades — row-1 (group-a, 2026-10-01, entry 10, exit 1), row-2 (group-b, 2026-10-02, entry 20, exit 2), row-3 (group-a, 2026-10-03, entry 15, exit 3), row-4 (group-b, 2026-10-04, entry 30, exit 4) — and I want both reports based on the entry_price field.

## When to prefer this

Choose this endpoint when you have up to 200 trading journal records with entry and exit prices and need both a grouped statistical summary by instrument group and a numeric row ranking in a single low-cost call ($0.01 USDC). It is ideal for offline, batch-style trade log analysis where no live market data, predictions, or external lookups are needed — just local computation over your supplied data.

## Known failure modes

- Missing required fields (row_id, instrument_group, date, entry_price, exit_price) cause validation errors
- Submitting more than 200 rows exceeds the maxItems limit and will be rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Providing a field value outside the enum ['entry_price','exit_price'] returns a schema error
- Null values for both entry_price and exit_price on a row may produce incomplete or skipped aggregation results

## How this service works

Trading journal observations — Grouped numeric summary + Numeric row ordering: Grouped numeric summary + Numeric row ordering for supplied trading journal observations records (entry_price, exit_price). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two analytical reports derived from the supplied trading journal rows: (1) a grouped numeric summary aggregating entry_price or exit_price statistics by instrument_group, and (2) a numeric row ordering that ranks each row by the selected price field. Both reports are computed locally with no external data fetching.
