# K-line field reference
 A K-line row has 8 fields — date, open, last, high, low, volume, amount, turnover. Two things trip people up most: the close price field is named last, not close; and every numeric value is a string, not a number.

## What the response looks like

 A real response from `GET /v1/kline?code=sh600519&count=2`:

```
{
 "ok": true,
 "endpoint": "kline",
 "tier": "free",
 "elapsed_ms": 701,
 "source": "multi",
 "data": [
 { "date": "2026-09-30", "open": "1239.53", "last": "1258.62", "high": "1268",
 "low": "1236.05", "volume": "38331", "amount": "4797250000", "turnover": "0.31" }
 ]
}
```
 The five outer fields are **the same on every endpoint**: `ok` (success), `endpoint` (name), `tier` (current tier), `elapsed_ms` (latency), `source` (where the data came from). The market data itself lives in the `data` array.


## The eight fields

 
 | 

| 
 | Field 
 | Meaning 
 | Unit / format 




 

| 
 | `date` 
 | Trading day 
 | `YYYY-MM-DD` 



| 
 | `open` 
 | Open price 
 | CNY 



| 
 | `last` 
 | **Close price** 
 | CNY 



| 
 | `high` 
 | High 
 | CNY 



| 
 | `low` 
 | Low 
 | CNY 



| 
 | `volume` 
 | Volume 
 | lots (1 lot = 100 shares) 



| 
 | `amount` 
 | Turnover value 
 | CNY 



| 
 | `turnover` 
 | Turnover rate 
 | percent value (`0.31` = 0.31%) 







## The two mistakes people make most


### Why is the close price called last instead of close?

 Because the same field means **latest price** during the session and **close price** after it. One name covers both, so you never have to switch field names based on the clock. If you are porting code, the mapping is `close → last`.


### Why are the numbers strings?

 `"1258.62"` is a string, not a number. This is deliberate — it **preserves precision**. Floating point across languages produces artefacts like `1258.6200000000001`, and prices and amounts are precision-sensitive. Convert on your side:

```
import requests

r = requests.get("https://api.ashareapi.com/v1/kline",
 params={"code": "sh600519", "count": 250}).json()

for row in r["data"]:
 close = float(row["last"]) # string -> float
 amount = float(row["amount"])
```

## Common misuses

 

- **Treating volume as shares** — it is **lots** (1 lot = 100 shares); multiply by 100 for shares.


- **Treating turnover as a fraction** — `0.31` means 0.31%, not 31%.


- **Reading data without checking ok** — on failure `data` may be empty or absent. Check `ok` first.


- **Looking for an adjust parameter** — the adjustment convention is fixed; the endpoint neither needs nor accepts one.
