Fetch NISA account trading rankings from major Japanese securities brokerages.

> **Note on ranking frequency:** Rakuten rankings are updated **monthly** (around the 2nd of each month), while SBI rankings are updated **weekly**. This means SBI data changes every week, but Rakuten data only changes once a month. Historical queries reflect these different update cycles.

## Installation

```bash
pip install pynisa
```

## Quick Start

### Python API

```python
import pynisa

# Fetch top 10 NISA stock ranking from Rakuten
result = pynisa.ranking("rakuten")
result.data    # pandas DataFrame
result.period  # "2026年2月1日～2026年2月28日"

# US stocks from SBI
result = pynisa.ranking("sbi", "us_stock_buy", count=5)

# Historical ranking (requires database)
result = pynisa.ranking("sbi", date="2026-03-07")

# Force live fetch (skip database)
result = pynisa.ranking("rakuten", live=True)

# Rank history for a ticker
result = pynisa.history("rakuten", "7974")

# List available dates
pynisa.dates("sbi")  # ["2026-03-14", "2026-03-07", ...]

# Sync database manually
pynisa.sync(force=True)
```

### CLI

```bash
# JP stock rankings from all brokerages (side by side)
nisa
```

## Supported Brokerages

| Brokerage | Asset Types | Update Frequency |
|-----------|------------|-----------------|
| Rakuten Securities (楽天) | JP/US/CN/ASEAN stocks, JP/Foreign ETFs | **Monthly** (~2nd of month) |
| SBI Securities | JP/US/CN stocks, US/CN ETFs, Funds | **Weekly** |

## Database

pynisa maintains a SQLite database of historical rankings, automatically downloaded from GitHub Releases on first use. The database is updated by GitHub Actions:

- **Every Monday** — captures SBI's weekly update
- **3rd of each month** — captures Rakuten's monthly update

The database is stored at `~/.cache/pynisa/nisa.db` and auto-synced when stale (> 1 day).
