帮忙修改指标

请问可以帮忙修改下这个指标吗？在最新标记的圈或者×上画一条白色的直线， 如果还能图中的最高点，最低点也画一条直线的话更好，Params Numeric turnpoint(4);//转折点数 Numeric minpoint(1);//最小区间Vars plot plt; Array<Numeric> xdata; Array<Numeric> ydata; Global Array<Array<Numeric>> qx(0); Global Numeric k; Tick tickdata; Series<Numeric> flag; global Numeric baseprice; Global Numeric lastdatetime; Numeric i; Numeric j; Numeric n; Numeric tempprice; Numeric tempdatetime;Events OnInit() { plt.figure();//独立画板 //data[0].HideKline; } OnBar(ArrayRef<Integer> indexs) { GetTick(tickdata,0); tempprice=IIF(Frequency=="tick",tickdata.last,Close); tempdatetime=IIF(Frequency=="tick",tickdata.datetime,date+time); if(BarStatus==0) { baseprice=tempprice; k=-1; flag=0; qx[0][0]=baseprice; } Else { if(lastdatetime<>tempdatetime) { if(flag<>-1 and tempprice<=baseprice-turnpoint) { flag=-1; k=k+1; qx[0][k]=baseprice; qx[1][k]=0; } if(flag<>1 and tempprice>=baseprice+turnpoint) { flag=1; k=k+1; qx[0][k]=baseprice; qx[1][k]=0; } if(flag==1) { while(tempprice>=baseprice+minpoint) { qx[1][k]=qx[1][k]+1; baseprice=baseprice+minpoint; //Commentary("baseprice="+text(baseprice)); } } Else if(flag==-1) { while(tempprice<=baseprice-minpoint) { qx[1][k]=qx[1][k]-1; baseprice=baseprice-minpoint; } } lastdatetime=tempdatetime; } } //PlotNumeric("baseprice",baseprice); if(BarStatus==2) { //Commentary(TextArray(qx)); for i=0 to GetArraySize(qx[0])-1 { n=qx[1][i]; for j=1 to abs(n) { xdata[0]=(i+1)*10; ydata[0]=qx[0][i]+j*n/abs(n)*minpoint; if(n > 0 ) plt.icon(Text(j), xData[0], yData[0], "ICO14"); Else plt.icon(Text(j), xData[0], yData[0], "lvyuan"); } } } }
