紧急求助!EA中如何调用该指标?
紧急求助!EA中如何调用该指标? 我有两年的外汇交易经验,今年以来运用一套超短线策略帐户资金开始出现增长。对于编程我有一些经验,对于EA我还是新手。 我想将我的策略用EA来实现。等EA基本做出来的时候与大家分享和改进。 现在的问题是:EA中用到指标slope direction line实现基本的趋势判断,但我不知到如何正确调用。 double iCustom( string symbol, int timeframe, string name, ... , int mode, int shift) 其中int mode是什么?具体对于slope direction line而言,mode应该是什么?下面语句中问号应该是什么? if(iCustom(NULL,PERIOD_M30,"Slope Direction Line",10,2,4,?,0)==?) {.....//趋势向上} slope direction line代码如下 //+------------------------------------------------------------------+ #property copyright "MT4 release WizardSerg <a href="mailto:wizardserg@mail.ru"wizardserg@mail.ru/a>, ?? ???????
