spider project to get buy_sell_volume from 4 Futures Exchanges in Chinese Mainland

Project description

主要功能

下载国内四大期货交易所历史成交与持仓排名数据。

脚本执行时间

  • 交易所与期货公司结算步骤完成后,网站公布当天数据。若结算延迟,则可能影响数据的正常发布;

  • 如果进行每日更新,则更新脚本的启动时间设置在当日下午五点之后,非交易日无数据。

交易所数据区别

2020年1月1日前,商品期货数据统计口径均按双边计算,金融期货按单边计算;之后均按单边计算。

  • CFFEX

    同一交易日所有品种持仓排名数据不在同一个页面呈现,以各自品种分开呈现;

  • INE

    暂无SC品种成交持仓排名数据公布;

  • DCE

    通过下载压缩包并解析txt文件来获取单个交易日数据,但部分交易日压缩包无数据;

    2008-08-28, 2011-12-02, 2013-11-27, 2013-11-28, 2013-11-29,

    2016-01-04, 2016-01-07, 2018-04-09, 2018-05-02

  • CZCE

    网页结构不统一,需要区别对待,公布品种级别的汇总数据。

交易所公布标准

  • CFFEX 单边持仓达到1万手以上(含)和当月合约前20名结算会员的成交量、持仓量
  • DCE 根据相关规则,期货品种信息公布活跃月份(双边持仓量大于、等于2万手)合约,期权品种信息公布活跃月份(标的期货合约双边持仓量大于、等于2万手)合约系列 。
