## Quick Start

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

-- All EntropyIO fills for a day
SELECT timestamp, coin, base_symbol, side, price, size, direction
FROM read_parquet('s3://hydromancer-reservoir/by_dex/io/fills/perp/all/date=2026-08-22/fills.parquet')
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/io/fills/perp/all/date=2026-08-22/fills.parquet')
GROUP BY base_symbol ORDER BY volume_usd DESC;
```
