# timeseries-1mn-stocks (TsFile)

Apache TsFile version of
[`chuyin0321/timeseries-1mn-stocks`](https://huggingface.co/datasets/chuyin0321/timeseries-1mn-stocks).

## Overview

**OHLCV** (open / high / low / close / volume) market series for many stocks. Each record is
one stock's open/high/low/close price and volume at a point in time.

- **Tickers:** `symbol`, **1500** stocks (e.g. `A`, `AAPL`, … `ZYNE`).
- **Coverage:** 1962-01-01 to 2023-09-11.
- **Scale:** 378,090 rows; `(symbol, datetime)` is unique.
- A small number of missing OHLCV values are kept as null (not imputed).

## Schema (TsFile structure)

- **Time** (INT64, milliseconds) — the bar timestamp.
- **symbol** (TAG) — the ticker, 1500 devices. Query one with `WHERE symbol='AAPL'`.
- **open / high / low / close / volume** (FIELD, DOUBLE) — the OHLCV measurements.

## Usage

Read `data.tsfile` with the Apache TsFile Java or Python SDK.
