由于外汇黄金交易的时间很长，我们不可能实时盯盘，经常由于错过信号而错过赚钱机会，那么有一款能够检测并发出警报的程序就很有必要了。mt5 提供的周期众多列入M1 M2 M3 M4 H1,H2,H6等比mt4多出不少，那我们如何编写优雅的警报代码呢！下面请听我徐徐道来：首先我们准备个数组 用于存储各个图表周期 各个数组名_chart_period[]ENUM_TIMEFRAMES//数据类型_chart_period[]= {PERIOD_M1,PERIOD_M2,PERIOD_M3,PERIOD_M4,PERIOD_M5,PERIOD_M6,PERIOD_M10,PERIOD_M12,PERIOD_M15, PERIOD_M30,PERIOD_H1,PERIOD_H2,PERIOD_H2,PERIOD_H3,PERIOD_H4,PERIOD_H6,PERIOD_H8,PERIOD_H12,PERIOD_D1 };然后 我们声明一个类 在类里面声明必要的bands(布林带)指标参数，和存储布林带上下轨值的数组在声明一个 working 函数用于判断值和发出警报1.for 图表周期2.引动指标赋值给句柄3.句柄拷贝到数组4.数组进行k线穿越判断5.发出警报(设置警报间隔秒数具体可以参考下文class bands {private:int bands_h;//句柄int bands_period;//布林周期double dev;//偏差double bands_mean[],bands_up[],bands_down[];//中上和下值数组
public:void working();//工作函数
bands(int bands_periods=14,double devs=2)//有参构造 { bands_period=bands_periods; dev=devs; } ~bands(){}; };//+------------------------------------------------------------------void bands::working() { int len = ArraySize(_chart_period);//获取图表周期长度 for(int i=0;i<len;i++) { bands_h=iBands(Symbol(),_chart_period,bands_period,0,dev,PRICE_CLOSE);//获取句柄 指标.句柄至数组(bands_h,bands_mean,bands_up,bands_down,0,5);
bool k_up = 交易.K线穿越某值(Symbol(),_chart_period,1,3,0,bands_up[1],bands_up[0]); bool K_down = 交易.K线穿越某值(Symbol(),_chart_period,2,3,0,bands_down[1],bands_down[0]);
if(k_up&&交易.单位时间do1(30)) { Alert(Symbol()+" "+EnumToString(_chart_period)+" 向 上上上 穿越布林带上轨了"); } if(K_down&&交易.单位时间do2(30)) { Alert(Symbol()+" "+EnumToString(_chart_period)+" 向 下下下 穿越布林带下轨了"); } } }//+------------------------------------------------------------------+最后 就是调用了 我们需要准备个EA模版1.引入类2.创造类对象3.调用工作函数
