取指标数据
通过获取系统自带的MACD指标数据，进行变色重建，实现起来非常方便，可以直接取到需要的数据。需要先建立指标句柄，再用CopyBuffer()函数取数据。
intmacd_handle =0;macd_handle =iMACD(Symbol(),Period(),12,26,9,PRICE_CLOSE);//取指标数据CopyBuffer(macd_handle,0,0,rates_total,macdBuffer);CopyBuffer(macd_handle,1,0,rates_total,signalBuffer);
填充缓冲区
生成自定义指标，其实就是填充缓冲区的过程，将指标线、柱图、填充区、箭头缓冲区数据进行赋值，就可以实现我们需要的效果。
在填充箭头缓冲区时，需要更改箭头的样式，并且只是在双线出现金叉、死叉时才赋值，所以还需要将0值位置设为空绘制区PLOT_EMPTY_VALUE。
PlotIndexSetInteger(5,PLOT_ARROW,225); PlotIndexSetInteger(6,PLOT_ARROW,226); PlotIndexSetDouble(5,PLOT_EMPTY_VALUE,0); PlotIndexSetDouble(6,PLOT_EMPTY_VALUE,0);
需要注意的是，采用循环遍历赋值的方式，循环变量起始值在初始加载指标时为1，加载之后为prev_calculated - 1，这样在循环体内，即加载了所有历史数据，也实时更新最新数据，不会重新计算所有历史值。
//给缓冲区赋值,起始值intstart =1;if(prev_calculated >1) { start = prev_calculated -1; }for(inti = start; i < rates_total; i++) {//循环体 }

文华技术人员：
1楼指标注释部分与执行部分混在一起了
您重新上传一下 正常格式的源码，我们分析看下。
另外1楼图片没有上传成功，您可以在如图位置上传图片
MT4指标和文华指标言语相差过大，需要联系相关同事来进行修改。
