# S&P 500 1-Minute OHLCV (TsFile)

Apache TsFile version of
[`jwigginton/timeseries-1mn-sp500`](https://huggingface.co/datasets/jwigginton/timeseries-1mn-sp500).

## Overview

Minute-level **OHLCV** (open / high / low / close / volume) bars for **S&P 500** tickers.

- **Coverage:** 2024-02-26 09:30 → 2024-03-11 16:00, **1-minute** granularity.
- **Scale:** 392,924 rows across **503 tickers**.
- Each row is one 1-minute bar for one ticker; `(symbol, datetime)` is unique.

## Schema (TsFile structure)

- **Time** (INT64, milliseconds) — the bar timestamp.
- **symbol** (TAG) — the ticker, 503 devices. Query one with `WHERE symbol='AAPL'`.
- **open / high / low / close / volume** (FIELD, DOUBLE) — the OHLCV measurements.

Missing OHLCV values in the source are kept as null (not imputed, not dropped).

## Usage

```python
from tsfile import TsFileReader
reader = TsFileReader("sp500_1mn.tsfile")
schemas = reader.get_all_table_schemas()   # table: "sp500_1mn"
```
