QuantDB 字段单位速查手册 — 全部数据集实测验证的单位、口径与陷阱（个股 volume=股/amount=万元、指数 volume=手、L2原始逐笔 l2_data/tick_data、technical % vs l1 小数、dividend_rate 百分数、PG 前缀 symbol）。用 QuantDB 数据做分析/回测/报告、判断成交量/成交额/股息率/换手率单位、读逐笔委托/成交/十档盘口、排查数据口径不一致时使用。触发词：字段单位、成交量单位、成交额单位、股还是手、万元、股息率、数据口径、L2、逐笔、委托、成交明细、十档盘口、tick_data、wind.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add qusong0627/quantmind/quantdb-fields@sha256:0a05f1b7ade0f822The line at the top of this page pins the label git:20260919.2eecb38, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
