本程序用于判断收盘价格突破ma15提示箭头并声音报警，向上破ma15出现蓝色箭头，向下破ma15出现红色箭头 ma参数可调，目前定义是15均线，可根据自己要求修改 ma-alert.mq4和ma-alert.ex4文件放在mt4所在目录\experts\indicators目录下 但是没有声音.谢谢.不胜感激. //+------------------------------------------------------------------+ //| Custom ma-alert.mq4 | //| Copyright 2007, 暗袖盈香 | //| 领域外汇论坛 http://www.fxxxt.cn | //+------------------------------------------------------------------+ #property indicator_chart_window #property indicator_buffers 2 #property indicator_color1 Blue //渣，蓝色箭头 #property indicator_color2 Red //沽，红色箭头 extern int shift = 0; extern int ma_period = 15; //ma参数值 double ma1; //ma的值 double buy, sell; int init() { //---- indicators SetIndexStyle (0, DRAW_ARROW, EMPTY, 1); SetIndexArrow (0, 233); SetIndexBuffer (0, buy); SetIndexEmptyValue (0, 0.0); SetIndexStyle (1, DRAW_ARROW, EMPTY, 1); SetIndexArrow (1, 234); SetIndexBuffer (1, sell); SetIndexEmptyValue (1, 0.0); //---- return(0); } int start() { for(int i = Bars - 1; i >= 0; i --) { ma1 = iMA(Symbol() , NULL , ma_period , 0 , MODE_SMA , PRICE_CLOSE , i ); buy = 0; sell = 0; // if(Close > ma1 && Open < ma1) //当前根烛开盘低于已定义均线，收盘高于已定义均线 { buy = Low - 20*Point; } if(Close < ma1 && Open > ma1) //当前根烛开盘高于已定义均线，收盘低于已定义均线 { sell = High + 20*Point; } } }ma-alert.mq4
