Reference

# Unit reference
 The same field name can carry different units on different endpoints: volume is always lots, but amount is CNY on K-line and CNY-10k on snapshot. Mixing them up throws the value off by 100x to 10,000x.

## 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**.




## Field by field

| 
 | Field 
 | Appears on 
 | Unit 
 | Basis 




 

| 
 | `open` `last` `high` `low` 
 | kline / quote 
 | CNY 
 | magnitude of live responses 



| 
 | `volume` 
 | kline / quote / snapshot / orderbook 
 | **lots** (×100 = shares) 
 | `/v1/orderbook` description: “volume is in lots (×100 = shares)” 



| 
 | `amount` 
 | **kline / quote** 
 | **CNY** 
 | price cross-check (below) 



| 
 | `amount` 
 | **snapshot** 
 | **CNY-10k** 
 | `/v1/snapshot` description: “`volume` lots · `amount` CNY-10k · market cap CNY-100m · share count shares” 



| 
 | Market cap (float / total) 
 | snapshot 
 | CNY-100m 
 | same 



| 
 | Share count (float / total) 
 | snapshot 
 | shares 
 | same 



| 
 | `turnover` 
 | kline / quote / snapshot 
 | percent value (`0.31` = 0.31%) 
 | three descriptions say “same name, same value (unit %)” 



| 
 | Order-book sizes `b1_v`–`a5_v` 
 | orderbook 
 | lots 
 | `/v1/orderbook` description 







## 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%.
