2016-9-3 使用Yahoo的接口也能夠獲取到數(shù)據(jù) https://github.com/lukaszbanasiak/yahoo-finance

通達(dá)信網(wǎng)站為券商系統(tǒng)提供交易數(shù)據(jù)下載，如：上證所有證券日線(xiàn)shlday.zip,深證所有證券日線(xiàn)szlday.zip。shlday.zip下載加壓后會(huì)得到sh000001.day、sh000002.day等312個(gè)獨(dú)立的數(shù)據(jù)文件，sh000001.day代表了上證股票000001的所有日線(xiàn)數(shù)據(jù)。

1.日線(xiàn)數(shù)據(jù)格式

1-4字節(jié) Date:LongInt; //日期5-8字節(jié) OPen:LongInt; //開(kāi)盤(pán)*100(元)9-12字節(jié) High:LongInt; //最高價(jià)*100(元)13-16字節(jié) Low:LongInt; //最低價(jià)*100(元)17-20字節(jié) Close:LongInt; //收盤(pán)*100(元)21-24字節(jié) Amount；//成交額25-28字節(jié) Volume:LongInt; //Volume 成交量(股)29-32字節(jié) // Reserved 保留值

2.python程序

本程序代碼將給定日線(xiàn)數(shù)據(jù)文件內(nèi)容輸出到csv文件以供后續(xù)程序分析用。

2.2.說(shuō)明

1. 函數(shù) open(path,”rb”) 參數(shù)’rb’ 指定只讀二進(jìn)制打開(kāi)
2. struct.unpack(“l(fā)”, stock_date) 將二進(jìn)制數(shù)據(jù)解碼為integer類(lèi)型
