获取对应周期的北向南向数据
提示
- 该数据通过
get_market_data_ex接口获取 - 获取历史数据前需要先用
download_history_data下载历史数据,可选字段为"northfinancechange1m"：一分钟周期北向数据,"northfinancechange1d"：日线周期北向数据 - VIP权限数据
#方式1：内置python
获取对应周期的北向数据
内置python
C.get_north_finance_change(period)
参数：
| 字段名 | 数据类型 | 描述 |
|---|---|---|
period | str | 数据周期 |
返回结果：
- 根据
period返回一个dict，该字典的key值是北向数据的时间戳，其值仍然是一个dict，其值的key值是北向数据的字段类型，其值是对应字段的值。该字典数据key值有：
| 字段名 | 数据类型 | 描述 |
|---|---|---|
| hgtNorthBuyMoney | int | HGT北向买入资金 |
| hgtNorthSellMoney | int | HGT北向卖出资金 |
| hgtSouthBuyMoney | int | HGT南向买入资金 |
| hgtSouthSellMoney | int | HGT南向卖出资金 |
| sgtNorthBuyMoney | int | SGT北向买入资金 |
| sgtNorthSellMoney | int | SGT北向卖出资金 |
| sgtSouthBuyMoney | int | SGT南向买入资金 |
| sgtSouthSellMoney | int | SGT南向卖出资金 |
| hgtNorthNetInFlow | int | HGT北向资金净流入 |
| hgtNorthBalanceByDay | int | HGT北向当日资金余额 |
| hgtSouthNetInFlow | int | HGT南向资金净流入 |
| hgtSouthBalanceByDay | int | HGT南向当日资金余额 |
| sgtNorthNetInFlow | int | SGT北向资金净流入 |
| sgtNorthBalanceByDay | int | SGT北向当日资金余额 |
| sgtSouthNetInFlow | int | SGT南向资金净流入 |
| sgtSouthBalanceByDay | int | SGT南向当日资金余额 |
示例1 通过内置python获取：
示例
# coding = gbk
def init(C):return
# 获取市场北向数据
def handlebar(C):print(C.get_north_finance_change('1d'))返回值
