fooltrader数据协议

该文档定义了fooltrader的数据协议,包括数据字段的含义,文件的存储目录结构,文件的格式,elastic search的mapping,kafka的schema.

1. 基础概念

  • 证券类型(type)
    stock,future,bond等
  • 交易所(exchange)
    sz,sh等
  • 代码(code)
    000338,600388等
  • 唯一标识标(security_id)
    结构为type_exchange_code,比如stock_sz_000338,代表A股中的潍柴动力.

2. 目录结构

2.1 存储根目录

设置环境变量FOOLTRADER_STORE_PATH="the/path/to/store/data" 或者在settings.py里面

#fooltrader的数据根目录
FOOLTRADER_STORE_PATH = '/home/xuanqi/workspace/github/fooltrader/data'

价格为不复权数据,利用复权因子,可以非常方便的得出前复权和后复权数据,算法为:
后复权价格=价格*复权因子
前复权价格=价格/最新的复权因子
可以看出,后复权价格是不变的,而前复权却依赖时间

c. tick数据

时间,价格,成交额,成交量,方向(买:1,卖:-1,中性:0)
timestamp,price,volume,turnover,direction
09:47:50,11.74,544,638656,-1
09:47:47,11.74,5483,6437088,0
09:47:44,11.75,572,672852,1

目前api读取的是文件,但提供了存储到es的方法,字段名称和含义是统一的,可以非常方便的在es和kibana中进行分析.

3.4. 事件数据

a. 业绩预告

description:描述,changeStart:变动范围最小值,preEPS:每股收益前值,type:类型(预减,预增),reportPeriod:业绩报告期,reportDate:这个公告发出的日期,change:变动

{
  "description": "预计2015年1月1日-2015年3月31日归属于上市公司股东的净利润为盈利:60,000万元–70,000万元,比上年同期下降:约54%-61%。",
  "changeStart": -0.61,
  "preEPS": 0.14,
  "type": "预减",
  "securityId": "stock_sz_000002",
  "reportPeriod": "2015-03-31",
  "id": "stock_sz_000002_2015-04-03",
  "reportDate": "2015-04-03",
  "change": -0.54
}

需要注意的是,为了不使用"未来函数",策略里面应该以reportDate为获取该数据的依据.
