+# Tessera Analytics Hyperliquid Order-Flow OHLCV (1-minute) — free sample
+
+A growing monthly sample of [`gold_ohlcv_1m`](https://tesseralytics.dev/datasets/gold_ohlcv_1m), the
+order-flow-enriched 1-minute OHLCV dataset served by [Tessera Analytics](https://tesseralytics.dev):
+open / high / low / close and volume for every minute, plus the order-flow context raw candles can't
+show — the aggressor buy/sell volume split, cumulative volume delta (CVD), distinct taker counts,
+taker fees and realized PnL, and the hourly forward-filled funding rate.
+
+**Coverage:** BTC, ETH, SOL, HYPE · 2026-08 → 2026-08 (UTC, month-grained) ·
+178,506 rows · 25 columns · 1-minute bars, one gzipped CSV per coin per month
+(`ohlcv_1m_<COIN>_<YYYY-MM>.csv.gz`). A new month is appended a few days after it closes.
+
+| Coin | Months | Rows | CSV (gz) |
+|---|---|---|---|
+| BTC | 1 (2026-08→2026-08) | 44,628 | 4.8 MB |
+| ETH | 1 (2026-08→2026-08) | 44,626 | 4.5 MB |
+| SOL | 1 (2026-08→2026-08) | 44,625 | 4.1 MB |
+| HYPE | 1 (2026-08→2026-08) | 44,627 | 4.6 MB |
+
+## Source & provenance
+
+Produced by the Tessera Analytics gold pipeline (Rust workers orchestrated by Dagster): raw Hyperliquid L1
+trade and funding data is ingested nightly from the Hyperliquid node archive, transformed through
+bronze → silver → gold stages, and published as Parquet. Each month's file is exported from the same
+production partition the API serves once that partition is final — the sample is **refreshed monthly**
+(appended, never truncated); the live API gets nightly updates. Per-month revisions are tagged
+(`v<YYYY-MM>` of the push that first added that month).
+
+## Quickstart
+
+Load locally (the sample is plain gzipped CSV):
+
+```python
+import polars as pl
+df = pl.read_csv("ohlcv_1m_BTC_*.csv.gz")
+print(df.select("time", "close", "cvd").tail())
+```
+
+Or pull live data with the official [`tessera-api`](https://pypi.org/project/tessera-api/) Python SDK
+(free API key, no card, at [tesseralytics.dev](https://tesseralytics.dev)):
+
+```python
+import tessera
+client = tessera.TesseraClient()  # reads $TESSERA_API_KEY
+df = client.read("gold_ohlcv_1m", "BTC", "2026-05")
+print(df.select("time", "close", "cvd").tail())
+```
+
+The [MCP server](https://tesseralytics.dev/mcp-server) exposes the same datasets to Claude and other
+MCP clients; the full dataset catalog is at
+[tesseralytics.dev/datasets](https://tesseralytics.dev/datasets).
+
+## Data dictionary
+
+`time` is the **start** of the minute (UTC; each bar covers [time, time+1min), so lag one bar before
+joining to point-in-time data). All columns are non-null.
+
+| Column | Meaning |
+|---|---|
+| `time` | Minute-bar start timestamp, UTC |
+| `coin` | Market symbol (this sample: BTC, ETH, SOL, HYPE) |
+| `open` / `high` / `low` / `close` | Candle prices for the minute |
+| `volume` | Total traded volume in the minute |
+| `buy_vol` / `sell_vol` | Volume on aggressor-buy / aggressor-sell fills |
+| `aggressor_delta` | `buy_vol − sell_vol` (per-bar) |
+| `cvd` | Running cumulative `aggressor_delta`, continuous across day/month boundaries (not reset within a file) |
+| `trade_count` | Number of trades in the minute |
+| `unique_takers` | Distinct taker accounts in the minute |
+| `vwap` | Minute VWAP |
+| `total_fees` / `taker_fees` / `maker_fees` | Fee aggregates for the minute |
+| `taker_open_long_vol` / `taker_open_short_vol` / `taker_close_long_vol` / `taker_close_short_vol` | Taker volume by open/close, long/short leg |
+| `closed_pnl_long` / `closed_pnl_short` | Realized PnL by side |
+| `funding_rate` | Hourly funding rate, forward-filled from funding events |
+| `bootstrap_source` | Running-state carry-over (`carried_from_prior` once history exists, `cold_start` at genesis) |
+
+## Known gaps
+
+Scattered minute-level gaps — 54 missing minutes of 178,560 (0.03%) so far, where the upstream Hyperliquid node archive had no data. No hour is fully missing.
+
+## Limitations
+
+- **Sample window:** this sample starts 2026-08 and grows month by month; the full dataset on
+  the API has complete multi-month history (from October 2025). The first sample month's CVD /
+  funding state is already stitched to the prior month's, so running-state columns are continuous
+  even where the sample itself begins mid-history.
+- Running state (`cvd`, `funding_rate`) is per-coin continuous across appended months.
+- Fees, realized PnL, funding, and open/close leg volumes reflect Hyperliquid's taker/maker model
+  only — this is DEX perp data, not CEX data.
+
+## Go beyond the sample
+
+Pro ($29/mo) unlocks the full history (from October 2025) plus all coins — including HIP-3 markets —
+and the `gold_funding_1h` and `gold_positioning_1h` datasets, via the same API. Free tier: `gold_ohlcv_1m`
+for BTC/ETH/SOL/HYPE, trailing 30 days, free key at [tesseralytics.dev](https://tesseralytics.dev).
