概述

各种股票软件，例如通达信、同花顺、大智慧，都可以实时查看股票价格和走势，做一些简单的选股和定量分析，但是如果你想做更复杂的分析，例如回归分析、关联分析等就有点捉襟见肘，所以最好能够获取股票历史及实时数据并存储到数据库，然后再通过其他工具，例如SPSS、SAS、EXCEL或者其他高级编程语言连接数据库获取股票数据进行定量分析，这样就能实现更多目的了。
为此，首先需要找到可以获取股票数据的接口，新浪、雅虎、腾讯等都有接口可以实时获取股票数据，历史数据选择了雅虎接口，收盘数据选择了腾讯接口。
（1）项目结构
（2）数据库连接池

（5）获取股票历史数据
采用雅虎的接口：http://ichart.yahoo.com/table.csv?s=<string>&a=<int>&b=<int>&c=<int>&d=<int>&e=<int>&f=<int>&g=d&ignore=.csv
参 数：s — 股票名称
a — 起始时间，月
b — 起始时间，日
c — 起始时间，年
d — 结束时间，月
e — 结束时间，日
f — 结束时间，年
g— 时间周期。
（一定注意月份参数，其值比真实数据-1。如需要9月数据，则写为08。）
示例 查询浦发银行2010.09.25 – 2010.10.8之间日线数据
http://ichart.yahoo.com/table.csv?s=600000.SS&a=08&b=25&c=2010&d=09&e=8&f=2010&g=d
返回：
Date,Open,High,Low,Close,Volume,Adj Close
2010-09-30,12.37,12.99,12.32,12.95,76420500,12.95
2010-09-29,12.20,12.69,12.12,12.48,79916400,12.48
2010-09-28,12.92,12.92,12.57,12.58,63988100,12.58
2010-09-27,13.00,13.02,12.89,12.94,43203600,12.94
因为数据量比较大，需要跑很久，所以也可以考虑多线程模式来获取相关数据，单线程模式：

（6）获取实时价格和现金流数据
A：实时价格数据采用腾讯的接口：沪市：http://qt.gtimg.cn/q=sh<int>，深市：http://qt.gtimg.cn/q=sz<int>
如获取平安银行的股票实时数据：http://qt.gtimg.cn/q=sz000001，会返回一个包含股票数据的字符串：
v_sz000001="51~平安银行~000001~11.27~11.27~11.30~316703~151512~165192~11.27~93~11.26~ 4352~11.25~4996~11.24~1037~11.23~1801~11.28~1181~11.29~2108~11.30~1075~11.31~1592~11.32~ 1118~15:00:24/11.27/3146/S/3545407/17948|14:56:59/11.26/15/S/16890/17787| 14:56:56/11.25/404/S/454693/17783|14:56:54/11.26/173/B/194674/17780|14:56:51 /11.26/306/B/344526/17777|14:56:47/11.26/16/B/18016/17773~ 20151029150142~0.00~0.00~11.36~11.25~ 11.26/313557/354285045~ 316703~35783~0.27~7.38~~11.36~11.25~0.98~1330.32~1612.59~1.03~12.40~10.14~";
数据比较多，比较有用的是：1-名称；2-代码；3-价格；4-昨日收盘；5-今日开盘；6-交易量（手）；7-外盘；8-内盘；9-买一；10-买一量；11-买二；12-买二量；13-买三；14-买三量；15-买四；16-买四量；17-买五；18-买五量；19-卖一；20-卖一量；21-卖二；22-卖二量；23-卖三；24-卖三量；25-卖四；26-卖四量；27-卖五；28-卖五量；30-时间；31-涨跌；32-涨跌率；33-最高价；34-最低价；35-成交量（万）；38-换手率；39-市盈率；42-振幅；43-流通市值；44-总市值；45-市净率
B：现金流数据仍然采用腾讯接口：沪市：http://qt.gtimg.cn/q=ff_sh<int>，深市：http://qt.gtimg.cn/q=ff_sz<int>
例如平安银行的现金流数据http://qt.gtimg.cn/q=ff_sz000001：
v_ff_sz000001="sz000001~21162.20~24136.40~-2974.20~-8.31~14620.87~11646.65~2974.22~ 8.31~35783.07~261502.0~261158.3~平安银行~20151029~20151028^37054.20^39358.20~ 20151027^39713.50^42230.70~20151026^82000.80^83689.90~20151023^81571.30^71743.10";
比较重要的：1-主力流入；2-主力流出；3-主力净流量；4-主力流入/主力总资金；5-散户流入；6-散户流出；7-散户净流量；8-散户流入/散户总资金；9-总资金流量；12-名字；13-日期
采用多线程、数据库连接池实现股票实时价格和现金流数据的获取：

（7）加入到系统任务计划中收集盘后数据
（8）收集后的数据可以用以分析了，例如：
求取10月28日主力净流入最大的股票：select * from stock_cash_tencent where main_net_cash = (select max(main_net_cash) from stock_cash_tencent where date = '20151028' )
原来是“兴蓉环境”，当日放量上涨，次日收跌，连续多日有主力资金流入。
excel中做分析：
平安银行的资金流量分析
