ｍｔ４的指标，很简单，只是我对编程没有细胞，还是请版主帮帮忙，谢谢版主。 指标要求：在图上划出２条线，第一条10个周期的平均线加上５％，也就是当日10周期平均值乘以1.05；第二条是10个周期的平均线减去５％，也就是当日10周期平均值乘以0.95 这个１０个周期可以更改，５％也可以更改，这个指标也可以应用到其他周期，入４Ｈ、１Ｈ等等的周期。

偶也是属于对指标编写没有细胞的人。。。。。。嘿嘿 还请朋友们帮忙哈

这个有实际意义吗? 比如EURUSD某点MA为1.17 时候如果+5%就是1.2285了, 这时MA已经在图形高点外 都显示不出来了. 还是改了一个，设置MA_Scale参数即可设置缩放比例，比如MA_Scale为1.01表示扩大1%, 0.995表示 缩小0.5%, 默认为1.01. 其他参数同标准MA，也支持SMA, EMA, SMMA, LWMA. 如果需要同一个图上显示多个不同缩放的MA指标, 则可以按标准MA同样的方式进行分次不同颜色添加. 具体代码如下，是以MT4自带的MA指标为基础修改的. //+------------------------------------------------------------------+ //| MA_Scale.mq4 | //| Copyright ?2004, MetaQuotes Software Corp. | //| http://www.metaquotes.net/ | //+------------------------------------------------------------------+ #property copyright "Copyright ?2004, MetaQuotes Software Corp." #property link "http://www.metaquotes.net/" #property indicator_chart_window #property indicator_buffers 1 #property indicator_color1 Red //---- indicator parameters extern int MA_Period=10; extern int MA_Shift=0; extern int MA_Method=0; extern double MA_Scale=1.01; //---- indicator buffers double ExtMapBuffer; //---- int ExtCountedBars=0; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { int draw_begin; string short_name; //---- drawing settings SetIndexStyle(0,DRAW_LINE); SetIndexShift(0,MA_Shift); IndicatorDigits(MarketInfo(Symbol(),MODE_DIGITS)); if(MA_Period<2) MA_Period=13; draw_begin=MA_Period-1; //---- indicator short name switch(MA_Method) { case 1 : short_name="EMA("; draw_begin=0; break; case 2 : short_name="SMMA("; break; case 3 : short_name="LWMA("; break; default : MA_Method=0; short_name="SMA("; } IndicatorShortName(short_name+MA_Period+")"); SetIndexDrawBegin(0,draw_begin); //---- indicator buffers mapping SetIndexBuffer(0,ExtMapBuffer); //---- initialization done return(0); } //+------------------------------------------------------------------+ //| | //+------------------------------------------------------------------+ int start() { if(Bars<=MA_Period) return(0); ExtCountedBars=IndicatorCounted(); //---- check for possible errors if (ExtCountedBars<0) return(-1); //---- last counted bar will be recounted if (ExtCountedBars>0) ExtCountedBars--; //---- switch(MA_Method) { case 0 : sma(); break; case 1 : ema(); break; case 2 : smma(); break; case 3 : lwma(); } //---- done return(0); } //+------------------------------------------------------------------+ //| Simple Moving Average | //+------------------------------------------------------------------+ void sma() { double sum=0; int i,pos=Bars-ExtCountedBars-1; //---- initial accumulation if(pos=0) { sum+=Close[pos]; ExtMapBuffer[pos]=(sum/MA_Period)*MA_Scale; sum-=Close[pos+MA_Period-1]; pos--; } //---- zero initial bars if(ExtCountedBars<1) for(i=1;i2) pos=Bars-ExtCountedBars-1; //---- main calculation loop while(pos>=0) { if(pos==Bars-2) ExtMapBuffer[pos+1]=Close[pos+1]*MA_Scale; ExtMapBuffer[pos]=(Close[pos]*pr+ExtMapBuffer[pos+1]*(1-pr)/MA_Scale)*MA_Scale; pos--; } } //+------------------------------------------------------------------+ //| Smoothed Moving Average | //+------------------------------------------------------------------+ void smma() { double sum=0; int i,k,pos=Bars-ExtCountedBars+1; //---- main calculation loop pos=Bars-MA_Period; if(pos>Bars-ExtCountedBars) pos=Bars-ExtCountedBars; while(pos>=0) { if(pos==Bars-MA_Period) { //---- initial accumulation for(i=0,k=pos;i=0) { ExtMapBuffer[pos]=(sum/weight)*MA_Scale; if(pos==0) break; pos--; i--; price=Close[pos]; sum=sum-lsum+price*MA_Period; lsum-=Close; lsum+=price; } //---- zero initial bars if(ExtCountedBars<1) for(i=1;i
