求助，MQL5获取分形指标数组的值不正确，不知道哪儿出错了！
没有错，这个很大的值1.797693134862316e+308 是EMPTY_VALUE，表示没有fractal。

。。。。。
//我也是搞了一个早上才解决，需要通过循环来获取值，自己封装了一个，源码如下： int Fractals(double &data0[],double &data1[],int count,string symbol,ENUM_TIMEFRAMES period) { int h=iFractals(symbol,period);//iCustom(symbol,period,"Examples\\Fractals");// ArraySetAsSeries(data0,true); ArraySetAsSeries(data1,true); int a; a=CopyBuffer(h,0,0,count,data0); a=CopyBuffer(h,1,0,count,data1); //IndicatorRelease(h); return(a); } void getFractals(double &FractalUp[],double &FractalDn[],int geshu) { ArrayResize(FractalUp,geshu); ArrayResize(FractalDn,geshu); ArrayInitialize(FractalUp,0); ArrayInitialize(FractalDn,0); double FractalUpzhi[],FractalDnzhi[]; int bars=Bars(Symbol(),0); Fractals(FractalUpzhi,FractalDnzhi,bars,Symbol(),0); int jishuup=0; for(int i=0; i<bars; i++) { if(jishuup>(geshu-1)) { break; } if(FractalUpzhi[i]!=EMPTY_VALUE) { FractalUp[jishuup]=FractalUpzhi[i]; jishuup++; } } int jishudn=0; for(int i=0; i<bars; i++) { if(jishudn>(geshu-1)) { break; } if(FractalDnzhi[i]!=EMPTY_VALUE) { FractalDn[jishudn]=FractalDnzhi[i]; jishudn++; } } }

返回的数组数值很奇怪： (GOLD,H1) 1.797693134862316e+308
这个double类型的数组是什么鬼，不应该是个价格数据吗？？请求高手求助帮忙解决，谢谢
