+
+Crypto market datasets collected as a by-product of our own research and
+published so they are not lost. One sub-folder per dataset; each appended
+nightly where collection is still running.
+
+| folder | what | coverage | cadence |
+|---|---|---|---|
+| `polymarket_updown_orderbook/` | Polymarket Up/Down (5m/15m) order books, 10 levels, BTC/ETH/SOL/XRP/BNB, with Binance spot reference | 2026-05-24 → present | appended nightly (previous UTC day) |
+

+
+## polymarket_updown_orderbook
+
+Continuous top-10-level order book snapshots for Polymarket's short-dated
+**crypto Up/Down markets** (5-minute and 15-minute, BTC/ETH/SOL/XRP/BNB),
+captured roughly every 2 seconds, with the Binance spot price, the market's
+strike and the time left to resolution on every row.
+
+- **Granularity:** one row per (market, snapshot); ~250 000 rows/day.
+- **Both outcomes:** the `Up` and `Down` books are recorded side by side.
+- **Layout:** `polymarket_updown_orderbook/data/date=YYYY-MM-DD/book_depth.parquet`
+  (Hive-style day partitions).
+
+Polymarket's CLOB API is live-only; to our knowledge no public archive of the
+order books of these short-dated markets exists.
+
+### Schema
+
+| column | type | meaning |
+|---|---|---|
+| `ts` | int64 | snapshot time, Unix seconds (UTC) |
+| `ts_ms` | float64 | snapshot time, Unix milliseconds (v2 rows; absent/null before 2026-06-11) |
+| `market` | string | market slug, e.g. `btc-updown-5m-1779622200` (asset-period-windowStart) |
+| `asset` | string | `btc`, `eth`, `sol`, `xrp`, `bnb` (others may appear for some periods) |
+| `period_min` | int64 | market length in minutes: 5 or 15 |
+| `condition_id` | string | Polymarket condition id (public market identifier, 0x…) |
+| `win_start_ts` | int64 | window start, Unix seconds (v2) |
+| `secs_left` | int64 | seconds until the window closes / market resolves |
+| `in_window` | bool | whether the market window is currently open |
+| `favored` | string | which side is priced above 0.5 at snapshot time (`Up`/`Down`) |
+| `spot` | float64 | Binance spot price of the underlying (REST ticker) fetched with the snapshot |
+| `spot_ts_ms` | float64 | timestamp of that spot observation, Unix ms (v2) |
+| `strike_spot` | float64 | first spot at/after window start = the market's strike (v2) |
+| `Up` | string (JSON) | `{"bids":[[price,size],…],"asks":[[price,size],…]}` — up to 10 levels each, best first |
+| `Down` | string (JSON) | same for the Down outcome |
+
+Prices in `Up`/`Down` are outcome-token prices in USDC (0–1); sizes are in
+shares. Parse with `json.loads` (Python) or `json_extract` (DuckDB).
+Schema v1 (19 days before 2026-06-11) has 11 columns; v2 has 15. Reading
+with `union_by_name`/`diagonal` concat handles both.
+
+### Quick start
+
+```python
+import polars as pl, json
+df = pl.read_parquet(
+    "hf://datasets/Barthel/variouscryptodata/polymarket_updown_orderbook/data/date=2026-08-21/book_depth.parquet")
+row = df.filter(pl.col("asset") == "btc").row(0, named=True)
+book = json.loads(row["Up"])
+print(book["bids"][0], book["asks"][0], row["spot"], row["secs_left"])
+```
+
+```sql
+-- DuckDB
+SELECT asset, period_min, count(*)
+FROM read_parquet('hf://datasets/Barthel/variouscryptodata/polymarket_updown_orderbook/data/*/*.parquet', union_by_name=true)
+GROUP BY 1,2 ORDER BY 1,2;
+```
+
+### Collection notes (read before modelling)
+
+- Best-effort single-host capture: short gaps (seconds to minutes) occur around
+  reconnects and host maintenance; treat `ts` spacing as irregular.
+- Snapshot cadence is ~2 s per market; several markets are active at once.
+- `spot` is the Binance spot price fetched by the collector at snapshot time,
+  not Polymarket's resolution oracle; use it for analysis, not as ground truth
+  for settlement.
+- Nothing here is investment advice; no trading strategy is included.
+- Every upload is scanned automatically for credentials before publishing.
