## Quick Start

```sql
INSTALL httpfs;
LOAD httpfs;
SET s3_region = 'ap-northeast-1';

-- BTCD fills for a day
SELECT timestamp, side, price, size, direction, address
FROM read_parquet('s3://hydromancer-reservoir/by_dex/para/fills/perp/all/date=2026-04-10/fills.parquet')
WHERE coin = 'para:BTCD'
ORDER BY timestamp;

-- Volume by market
SELECT base_symbol, sum(price * size) as volume_usd, count(*) as trades
FROM read_parquet('s3://hydromancer-reservoir/by_dex/para/fills/perp/all/date=2026-04-10/fills.parquet')
GROUP BY base_symbol ORDER BY volume_usd DESC;
```
