PowerLanguage概述 5

1300=1:00PM、130000=1:00:00PM。

在PL中的日期是以YYYMMdd格式，其中YYY表示自1900至今的年份，MM表示月，dd表示日。这种格式又叫EL格式。如2013年1月4日的EL格式为1130104。 F.变量

变量用来存储数值、字符串或逻辑值（true/false）。存在变量中的值可在整个脚本中通过变量名称来引用，并可用在任何时间有脚本改变。变量使用前需要先声明。更多信息，请看关键字Variable G.数组

数组是多元素的变量，更多信息，请看关键字Array 二、脚本如何执行

PowerLanguage公式可用在由MultiCharts创建的图表和投资组合回测（Portfolio Backtester）中。

可用的PL公式分为两个主要类型：指标（Indicators）和信号（Signals）。

一个指标是一个可视的技术分析工具，用来分析市场条件、定义和预测趋势以及市场模式。指标即是一个可视化的数学公式，包含一个或多个画线、直方图、一系列点或穿越状态、高价和低价、左右的tick或在一个图上包含以上全部的信息。指标的计算只能用价格、成交量数据。

一个信号是一个机械的技术分析工具，用来系统地根据一系列交易规则指定进场或出场点位。交易点位在图表上以文字和箭头标示。策略可以容易地由多个信号组合。由信号指定的进出场点位，可以用来发送委托单到交易商，完成全自动的交易执行。

根据它们不同的使用目的，指标和信号对于价格数据的计算有不同的方式。下面分别阐述两者。

在阐述前，需要先了解两个基本概念：完成bar和指标运算参考的最大bars数量。 A.完成bar

当一个bar已经收盘并且无法加入额外的tick时，可认为此bar是一个完成bar。

*基于时间的图表，一旦设定的bar周期的时间间隔已过，下一个时间戳的第一笔tick已接收到，那么这个bar为已收盘；或者三秒内没有再收到额外的tick，也视为这个bar已经结束。

*基于tick的图表，一旦定义的bar数量已经到来，则这个bar视为已结束。

| PowerLanguage概述

5

6 PowerLanguage概述

*基于范围的图表，一旦接收的新tick的价格超出原始的价格范围，则这个bar视为已结束。

*基于量的图表，一旦接收到的tick为当前bar所带来的成交量达到定义的合约数目，则这个bar视为已结束。

*基于变动的图表，一旦接收到的tick为当前bar所带来的的价格达到定义的价格变动数，则这个bar视为已结束。 B.指标运算参考的最大Bars数量

一个公式脚本可以参考前面bars的值来用于当前bar的计算。当在脚本中参考了前面N根bar，则公式可以从第N+1根bar开始可以看到绘图或委托行为。为了能让脚本开始执行计算， 前面预留了bars数目，叫做指标运算参考的最大Bars数量，或MaxBarsBack。MaxBarsBack的值可以选择「自动检测」或「用户指定」（可在设置指标->属性中设定）。

当选择为「自动检测」时，MaxBarsBack将会初始化为指标中引用的最大数据偏移量（即最大的N Bars Ago中的N值）。然而，脚本中引用的数据偏移如果是变量，MaxBarsBack的初始值可能会太小；在这种情形下，MaxBarsBack的值将自动增加5或乘以1.618，产生一个较高的值，在重新计算指标。

MaxBarsBack自动检测的过程可能会导致：在指标第一次应用到图表上时，某些函数在图上最开始的一些bar的计算重复。为了避免这种情况，MaxBarsBack可以设定为「用户指定」。

选择最小的MaxBarsBack来满足一个特定的指标或信号的计算，可手动设定这个值。推荐的初始值为50。 1.指标执行方式

指标的目的是在图表上绘出可视的数学公式，绘图的创建基于一个或多个价格数据系列。

当指标被插入到图表中时，第一次的计算是对于完成bar一个接着一个的计算，并从图上第一个bar开始。整个脚本对于每个完成bar都执行一次。在每个bar上，依据计算结果，指标脚本可以向外输出图形、文字、改变绘图颜色、音频警报等。如果指标脚本中含有前面bar的引用值，那么指标执行输出的第一个Bar将跟随“指标参考运算的最大Bars数量”的不同而不同。

一旦图上所有的完成bar都执行完成，一个指标将继续执行图上最后一个bar，以tick by tick的运算，不等待这根bar的形成。一个未完成bar是自上一个bar完成以来，接收到的所有tick的总和。新的一笔tick接收时，整个脚本将会在那根Bar执行，直到此bar已完

6

PowerLanguage概述

PowerLanguage概述 7

全形成并且下一个Bar已开始。指标脚本对于未完成bar的方式和已完成bar相同，并可以在基于未完成bar的计算结果上做出行动。

请注意只有最后的未完成bar在每一个新的tick收到时会重新计算，并非整个数据系列。

指标在一个bar的执行过程叫做重新计算或更新。默认指标更新是基于每笔tick资料的。但是，在某些情形下，它可能出现不良状况；

每笔tick更新大量的复杂指标需要更多实质性的系统资源。每笔tick资料都更新的操作可以在MultiCharts的设置中关闭。 2.信号执行方式

信号是策略的基本组件。信号实质上比指标更复杂，需要考虑大量的因素。信号支持回测和自动交易执行。

当信号被插入到图表中时，第一次的计算是对于完成bar一个接着一个的计算，并从图上第一个bar开始。整个脚本对于每个完成bar都执行一次。在每个bar上，依据计算结果，信号脚本可以执行一个或多个交易委托。委托单会在图上标记箭头或其他标识，可伴有弹出框或音频警报等。如果信号脚本中含有前面bar的引用值，那么信号执行输出的第一个Bar将跟随“指标参考运算的最大Bars数量”的不同而不同。

默认，一旦图上所有的完成bar都执行完成，一个信号将中断执行，直到新的完成bar已形成，然后全部脚本会在新的bar再次执行。

信号执行方式可以选择启用bar内交易来调整。当开启bar内交易执行状态为已启用时，信号对于最新的bar计算不用等到它的完成。而是，每当新的一笔tick接收到时，最新的bar就会重新计算一次，直到这根bar的完成并且下一根bar已经开始。一个未完成bar是自上一个bar完成以来，接收到的所有tick的总和。启用bar内模式，信号脚本对于未完成bar的方式和已完成bar相同，并可以在基于未完成bar的计算结果上做出行动。

请注意只有最后的未完成bar在每一个新的tick收到时会重新计算，并非整个数据系列。 A.委托单执行优先级

一个信号可以在一个bar中执行多个委托单。委托单可以由相同或不同的语句执行。

根据执行语句类型的不同，委托单的执行分为3组： 1.由 This Bar [On] Close语句执行

2.由 Next Bar [At] Market和Next Bar [At] Open语句执行

3.由Next Bar [At] Price Limit和Next Bar [At] Price Stop语句执行

| PowerLanguage概述

7

8 PowerLanguage概述

在一个委托组内，委托单执行的优先级排序是基于当前部位（持仓）的：

委托单执行优先级表 数值高者优先级高 持仓部位 无持仓(Flat) 多头(Long) 1 1 多头进场(Long Entry) 1 2 空头进场(Short Entry) - 1 多头出场(Long Exit) - - 空头出场(Short Exit) 空头(Short) 2 1 - 1 多个同方向的委托被分配的相对于彼此的优先级，是基于委托语句在信号脚本中的列表顺序而顺序执行。当多个信号组合来创建一个策略时，由不同信号执行的、同方向的委托被分配的相对于彼此的优先级，是基于委托单所在信号出现在信号标签中的顺序。先插入到图表中的信号顺序靠前。

一旦委托单被排序后，优先级最高的先执行。有一个重要注意事项：与当前持仓部位方向相反的进场委托，不是简单的只平掉当前的持仓，而是会反向开仓。比如：当持有1手空头(Short)时，1手多头(Long)的进场委托，结果将会是平掉空头持仓，并且建立1手多头持仓。

考虑到持仓部位的变化、委托单执行的结果，余下的委托单将会再排序，最高优先级的委托仍然先执行。

这个过程一直重复，直到全部的委托单都已执行，或直到剩下的委托没有可以被执行的。比如：只剩出场委托单，而当前已经没有持仓。

如果所剩的进场委托方向和当前持仓部位相同，那么在部位限制启用（打勾）的状态下，这些委托单可以被执行。部位限制的设定可最多允许N笔与目前仓位同向的进场委托单（详细见策略属性->属性->部位限定）。

剩下的不可执行的委托单会被丢弃。

B.委托单执行优先级举例：

在如下委托中：空头出场(SX)、空头进场(SE)、多头进场(LE)、多头出场(LX)、多头进场(LE)，当前持仓部位为空头，则多个委托单执行状况如下：

1.委托单的顺序根据优先级以降序排列：多头进场(LE)、多头进场(LE)、空头出场(SX)、空头进场(SE)SX SE LE LX LE （不可执行委托：多头出场(LX)） 2. 多头进场(LE)执行；当前持仓为多头 SX SE √ LX LE 8

PowerLanguage概述

PowerLanguage概述 9

3.委托单的顺序根据优先级以降序排列：空头进 场(SE)、多头进场(LE)、多头出场(LX)（不可执行委 托：空头出场(SX)） 4. 空头进场(SE)执行；当前持仓为空头 5. 委托单的顺序根据优先级以降序排列：多头进场(LE)、空头出场(SX)（不可执行委托：多头出场 (LX)） 6. 多头进场(LE)执行；当前持仓为多头 7. 委托单的顺序根据优先级以降序排列：多头出场(LX)（不可执行委托：空头出场(SX)） 8.多头出场(LX)执行；当前无持仓 9.只剩一个空头出场(SX)的委托，不可执行，将被丢弃。 SX √ SX √ √ LX LE SX √ √ √ √ LX √ √ √ √ √ SX √ 以上委托单执行结果，将从一个空头持仓变成无持仓。 三、字典阅读

本书为MultiCharts软件的编程语言PowerLanguage的字典功能，提供了详细的中文说明。

章节依照公式编辑器的字典顺序而排，即按照功能和字母顺序。文字所使用的颜色代表不同类型含义。经测试的注意事项，会以红色标识；无特别指定类型的，会以灰色标识。重点事项，会以加粗标识。其他分别举例如下： 函数 Getaccount（来自第1章 Getaccount语法） 关键字 Alert（来自第2章 Alert语法） 全局变量 Value1~ Value999，Condition1~ Condition99 变量 ID(来自第2章 AlertEnable范例） 参数 Overnight（来自第6章 False范例） 数组 ArrayName1（来自第9章 Array语法） 数值 3（来自第1章 Getaccount范例） 字符串 \（来自第1章 Getaccount范例） 跳跃字 Of（来自第7章 Ago范例） 其中全局变量为PowerLanguage内置的变量，使用较为方便快捷， | PowerLanguage概述

无需自定义。自定义的变量，程序的可读性较强。

各字典的标题中如有单斜线“/”分开的两个或多个，它们是同等的含义。如：第7章中Close/C，都是收盘价的含义，而C是Close的简写。

对于特定的行情趋势或反转点等其他情形，我们希望能够在图上有特别的标识，方便观看和判断。那么，在MultiCharts图表窗口中，使用绘图工具可以增加向上或向下的箭，而此功能也可以用策略程序来实现，本章则详细说明了程序实现画箭头的方法。

取得箭头物件的颜色（RGB色码或传统色码）。 Arw_GetColor(ObjectID) ObjectID——数值表达式，箭头物件的编号。 数值——箭头颜色编码； -2——无效的箭头物件编号。 ObjectID是在箭头物件被创建时Arw_New对应的返回值。 第3章 Arrow drawing画箭头
