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
