Unit reference

The short version

• volume is always lots, not shares — multiply by 100 for shares.
• amount differs by endpoint: CNY on K-line / quote, CNY-10k (万元) on /v1/snapshot.
• Market cap is CNY-100m (亿元), share count is shares, turnover rate is a percent value (0.31 = 0.31%).
• Every price is in CNY, and every numeric value is a string.

How to verify it yourself

Do not take the descriptions on faith — run a price cross-check. Two steps:

Step 1 — take one day of K-line and compute amount ÷ (volume × 100):

4797250000 ÷ (38331 × 100) = 1251.5

Step 2 — see whether that number falls inside the day’s low ~ high. The range that day was 1236.05 ~ 1268, and 1251.5 lands inside it.

That single check proves two things at once: volume is in lots (you must multiply by 100 to get shares), and amount is in CNY. If either unit were wrong, the result would be off by 100x or 10,000x — obvious at a glance.

The same check holds on a second day: 3260060000 ÷ (26366 × 100) = 1236.5, inside that day’s 1230.88 ~ 1245.87.

Common misuses

• Treating amount as CNY-10k — on K-line / quote it is CNY; assuming CNY-10k is off by 10,000x.
• Treating volume as shares — it is lots; multiply by 100 for shares.
• Mixing amount across endpoints — /v1/kline is CNY, /v1/snapshot is CNY-10k; the same name differs by 10,000x.
• Treating turnover as a fraction — 0.31 means 0.31%, not 31%.
