MT4 EA编写入门（最易学经典）本人精心整理
【第六课】:阴阳太极首先教你第一招：阴阳太极打开你的metaeditor打开你的my1ea002我先用中文编写一次你就明白我们等下要编写什么我们要编写。。。
如果（没有任何单和 青bar //上升的趋势）{可以下注买上的单}
如果（没有任何单和 红bar //代表下降低趋势）{可以下注买下的单}
ok就这么简单
你还记得要要求ea的编写方程式吗？对，就是if(){}
编写结果如下：//+------------------------------------------------------------------+//| my1ea.mq4 |//| http://www.mt4ea,com |//+------------------------------------------------------------------+#property copyright "Copyright ?2009, 柒侠伍义"#property link "http://www.mt4ea,com"
//+------------------------------------------------------------------+//| expert initialization function |//+------------------------------------------------------------------+int init(){//----
//----return(0);}//+------------------------------------------------------------------+//| expert deinitialization function |//+------------------------------------------------------------------+int deinit(){//----
//----return(0);}//+------------------------------------------------------------------+//| expert start function |//+------------------------------------------------------------------+int start(){//----
if(OrdersTotal()==0&& Close>Open){OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,Ask+TakeProfit*Point,"macd sample",16384,0,Green);}
if(OrdersTotal()==0&& Close<Open){OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,Bid-TakeProfit*Point,"macd sample",16384,0,Red);}//----return(0);}//+------------------------------------------------------------------+ OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,Bid-TakeProfit*Point,"macd sample",16384,0,Red);OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,Ask+TakeProfit*Point,"macd sample",16384,0,Green);
以上两个OrderSend是从macd samplecopy & press 过来的
还没有结束。。。。
把这两个改一改就可以了OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,Bid-TakeProfit*Point,"macd sample",16384,0,Red);OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,Ask+TakeProfit*Point,"macd sample",16384,0,Green);
Lots改成1TakeProfit改成2000 改成Bid+200*Point0 改成Ask-200*Point
变成OrderSend(Symbol(),OP_SELL,1,Bid,3,Bid-+200*Point,Bid-200*Point,"macd sample",16384,0,Red);OrderSend(Symbol(),OP_BUY,1,Ask,3,Ask-200*Point,Ask+200*Point,"macd sample",16384,0,Green);按《编写》如果0错误 0警告你的my1ea002成功了
