问题 According this solution Struts2 handle multiple actions... I know the Struts2 DMI can handle multiple acitons in single form easily. Recently, Struts2 turned off DMI mechanism for security issue. Now, we use WILDCARD MAPPINGS to map all actions in struts.xml example: <action name="*/*" class="action.{1}Action" method="{2}"> ... </action> In WILDARD MAPPINGS, it has a little problem to deal with mapping multiple actions/methods in single form. <s:form action="actionA/method2" theme="simple" >

DMI指标配合阶段高低价的量化交易策略

DMI指标 趋势交易者的主要目标是在趋势方向上买入或卖出资产。仅从资产价格中读取方向信号可能很困难并且经常会产生误导,因为价格通常在两个方向上波动并且在低波动率和高波动率之间变化特征。 定向运动指示器(也称为定向运动指标或DMI)是评估价格方向和强度的有用工具。它由J. Welles Wilder于1978年创建,他也创造了流行的相对强弱指数(RSI)。DMI对趋势交易策略特别有用,因为它区分强弱趋势,允许交易者只进入具有真实动量交易标的。DMI适用于所有时间范围,可应用于任何交易标的(股票,共同基金,交易所交易基金,期货,商品,数字货币和法定货币)。 虽然它的计算有些复杂,但DMI会告诉您何时做多或做空。在这里,我们将详细介绍如何分析DMI指标,并向您展示它可以揭示哪些信息,以帮助您获得更好的利润。 DMI趋势线 DMI是给定时期内范围扩展的移动平均值(默认值为14天)。正向移动指标(+DMI)衡量价格向上移动的强度;负向移动指标(-DMI)衡量价格向下移动的强度。这两条线反映了牛与熊的相应强度。 每个DMI由一条单独的线表示。首先,看看两条DMI线中哪条线位于顶部。一些短线交易者称这条顶部的线是主DMI线。主DMI更强,更有可能预测价格方向。为了让买家和卖家改变主导地位,两条线必须金叉或者死叉。 当底部的DMI穿过顶部的主DMI时发生交叉。交叉似乎是一个明显的多头/空头信号

1.Shell语言是什么类型的语言? SHELL语言是指UNIX操作系统的命令语言,同时又是该命令语言的解释程序的简称。 Shell本身是一个用C语言编写的程序,它是用户使用Unix/Linux的桥梁,用户的大部分工作都是通过Shell完成的。Shell既是一种命令语言,又是一种程序设计语言。作为命令语言,它交互式地解释和执行用户输入的命令;作为程序设计语言,它定义了各种变量和参数,并提供了许多在高级语言中才具有的控制结构,包括循环和分支。 它虽然不是Unix/Linux系统内核的一部分,但它调用了系统核心的大部分功能来执行程序、建立文件并以并行的方式协调各个程序的运行。因此,对于用户来说,shell是最重要的实用程序,深入了解和熟练掌握shell的特性极其使用方法,是用好Unix/Linux系统的关键。 2.Shell语言的执行方式有哪些? bash script-name 或者 sh script-name;   这是当脚本文件本身没有可执行权限(即文件权限属性x位为-号)时常使用的方法,或者脚本文件开头没有指定解释器时需要使用的方法。 推荐使用这种方法 。 path/script-name或者./script-name; 指在当前路径下执行脚本(脚本需要有执行权限),需要将脚本文件的权限改为可执行(即文件权限属性为x位)。具体方法为:chmod a+x script-name
