根据上一篇下载的数据，现在每天更新day数据
需要保证股票当日新上市下载，退市保留，停牌复牌识别、是否发生复权（决定前复权价格是否变化）
数据更新
1、大盘指数数据（399001, 399005, 399006, 399300，999999）

2、A股股票数据与概括文件
## R

文件夹内不能随便新建文件！！！ ## 1.设置截至日期（若补当日数据，五点之后执行） new.date <- "20171221" end.date <- paste(substr(new.date, 1, 4), substr(new.date, 5, 6), substr(new.date, 7, 8), sep = "-") ## 2.摘取当日在市股票代码 stock.code.df <- w.wset(‘sectorconstituent‘, paste0("date=", end.date, ";sectorid=a001010100000000")) if(stock.code.df$ErrorCode == 0){ # if(gsub("-", "", as.Date(stock.code.df$Time)) == new.date){ stock.code.sh.sz <- stock.code.df$Data$wind_code # }else{ # print("获取时间出错") # } }else{ print(paste0("获取数据出错，错误代码", stock.code.df$ErrorCode)) } new.stock.code <- substr(stock.code.sh.sz, 1, 6) # str(stock.code.sh.sz) ## 3.获取上一次数据日期 old.file.name <- gsub("股票数据", "", dir("股票数据")) last.data.day <- old.file.name[which.max(old.file.name)] ## 是否需要改为数值型比较 ## 4.数据上一次所有股票代码 old.stock.code <- gsub(".csv", "", dir(paste0("股票数据/股票数据", last.data.day))) ## 5.创建新的文件夹 dir.create(paste0("股票数据/股票数据", new.date)) ## 6.股票补全部分 ## 概括性文件变量 ## 退市数据保留执行以下部分代码，不保留执行已有那一行注释代码 all.stock.code <- unique(c(new.stock.code, old.stock.code)) general.information <- data.frame(array(dim=c(length(all.stock.code), 5))) # general.information <- data.frame(array(dim=c(length(stock.code.sh.sz), 5))) colnames(general.information) <- c("stock.code", "stock.name", "type", "starttime", "endtime") ##
