股票投资，抄底很难，因为抄底要知道什么时间洗盘结束，就是知道洗盘结束，也不一定是买点。今天给大家提供一套主图和附图指标，供大家买卖股票的参考。

附图提示洗盘结束，主图线变红买入。

界面如下:

/usr/bin 对/bin目录的一些补充

EMA21:=EMA(C,10),COLORYELLOW;

沪市上证指数 2010 年 1 月 6 日 BBD 指标出现负值之后，连续维持在负值状况，股指连续 22 个交易日调整。见图 1-4。

VAR2:=LLV(LOW,10);

我喜欢用 Mod-p（一个 xmonad 中 dzen 菜单栏的快捷方式，但是在大多数传统的桌面环境中该功能的快捷键是 Alt-F2）来启动程序（LCTT 译注：xmonad 是一种平铺桌面；dzen 是 X11 窗口下管理消息、提醒和菜单的程序）。这个设置在不运行多个 emacs 们 (emacsen)时很方便，因为这样就不会在试图捕获另一个打开的文件时出问题。这中方法很简单：创建一个叫 em 的脚本并将它放到我自己的环境变量中。就像这样：

GJJ:=EMA(攻击流量,8);

三是，在AI领域，由于技术原因，更多的论文是开源代码的，一方面，促进了更多人参与进来改进迭代；另一方面，科研跟工程实现无缝连接，一篇论文可以拉动从核心代码到平台，到具体应用很大范围的价值扩散。一篇论文很可能就是一个领域，一条赛道，甚至直接驱动业务价值和客户价值的大幅提升。

1.断点调试，源码分析

可以从源码了解到，不仅仅支持flv，ts，还有mp3，AAC等格式。SrsLiveEntry表示是一一对应关系，url与source的映射关系。对应源码如下：
