量化交易学习笔记-3月4日

短暂的股灾让人成长！
敦煌种业 3.01% 东方电气 5.20% 沙特 etf 0.60%
3月3日总结：再次对肖萌当时说的需要把股票分类深刻的理解。不同市值，不同板块的股票确实又会不同的表现。 在中国股市可能真的要适应中国国情。另外就是不要看别人的评论，自己内心不坚定的情况下，很容易收到影响。一定要基于数据说话。我简单的认为白银应该和黄金一样，但是实际上并没有数据支撑，吃到了最大的损失。
今天试试板块战法，敦煌种业太高了，我换上相关的冠衣股份，东方电气太高了，换了我自己算法支撑的望变电气 和 森源电气 ，看看 6 字头和 0 字头明天的表现差异。
3-4日购买：  603191 望变电气
002358 森源电气
600251 冠衣股份
