一个用Python编写的股票数据（沪深）爬虫和选股策略测试框架 - 爱你一万年123
一个用Python编写的股票数据（沪深）爬虫和选股策略测试框架
一个股票数据（沪深）爬虫和选股策略测试框架，数据基于雅虎YQL和新浪财经。
- 根据选定的日期范围抓取所有沪深两市股票的行情数据。
- 根据指定的选股策略和指定的日期进行选股测试。
- 计算选股测试实际结果（包括与沪深300指数比较）。
- 保存数据到JSON文件、CSV文件。
- 支持使用表达式定义选股策略。
- 支持多线程处理。

运行时参数
--storepath c://test --output csv --startdate 2015-09-01 --enddate 2015-12-07 --charset utf-8 --testfile ./portfolio_test.txt --reload Y --portfolio Y --thread 10能干什么
如果你想基于沪深股市行情数据进行一些工作，它可以帮助你导出指定时间范围内所有沪深A股的行情数据和一些技术指标，包括代码、名称、开盘、收盘、最高、最低、成交量、均线、KDJ等。
还有些什么问题
行情数据目前来源于雅虎YQL，每日数据的更新时间不太稳定（一般在中国时间午夜左右）。
环境
Python 3.4以上
pip install requestspip install pymongo
使用
python main.py [-h] [--reload {Y,N}] [--portfolio {Y,N}] [--output {json,csv,all}] [--storepath PATH] [--thread NUM]
[--startdate yyyy-MM-dd] [--enddate yyyy-MM-dd]
[--targetdate yyyy-MM-dd] [--testrange NUM] [--testfile PATH]
可选参数
-h, --help 查看帮助并退出 --reload {Y,N} 是否重新抓取股票数据，默认值：Y
--portfolio {Y,N} 是否生成选股测试结果，默认值：N
--output {json,csv,all} 输出文件格式，默认值：json
--charset {utf-8,gbk} 输出文件编码，默认值：utf-8
--storepath PATH 输出文件路径，默认值：~/tmp/stockholm_export
--thread NUM 线程数，默认值：10
--startdate yyyy-MM-dd 抓取数据的开始日期，默认值：当前系统日期-100天（例如2015-01-01）
--enddate yyyy-MM-dd 抓取数据的结束日期，默认值：当前系统日期
--targetdate yyyy-MM-dd 测试选股策略的目标日期，默认值：当前系统日期
--testrange NUM 测试日期范围天数，默认值：50
--testfile PATH 测试文件路径，默认值：./portfolio_test.txt

行情数据抓取范例
获取从当前日期倒推100天(不是100个交易日)的所有沪深股票行情数据。
执行完成后，数据在当前用户文件夹下./tmp/stockholm_export/stockholm_export.json
python main.py如果想导出csv文件
python main.py --output=csv选股策略测试范例
选股策略范例文件内容如下(包括在源码中)
选股策略”method 1”是:前前个交易日的KDJ指标的J值小于20+前个交易日的KDJ指标J值小于20+当前交易日的KDJ指标J值比上个交易日大40+当前交易日成交量变化大于100%
## Portfolio selection methodology sample file[method 1]:day(-2).{KDJ_J}<20 and day(-1).{KDJ_J}<20 and day(0).{KDJ_J}-day(-1).{KDJ_J}>=40 and day(0).{Vol_Change}>=1
以当前系统日期为目标日期进行倒推60天得选股策略测试。
不重新抓取行情数据并执行测试命令。
执行完毕后，会将测试结果按照每天一个文件的方式保存在./tmp/stockholm_export/。
文件名格式为result_yyyy-MM-dd.json(例如result_2015-03-24.json)。
python main.py --reload=N --portfolio=Y通过更改测试文件中的选股策略公式，可以随意测试指定时间范围内的选股效果。
