bar的绝对编号：
  1. Value1=Text_New(Date,Time,low-5 point,NumToStr(symbol_currentbar,0));
复制代码
bar的相对编号：
  1. Value2=Text_New(Date,Time,high + 5 point,NumToStr(currentbar,0));
复制代码
【currentbar】与【BarNumber】异同
  1. Value3=Text_New(Date,Time,high+5 point,NumToStr(BarNumber,0));
复制代码
最大bar数量（maxbarsback）【强制预留bar数量】

输出前5个bar的绝对编号与价格
  1. switch symbol_currentbar begin

  3. case 5 : begin

  5. print("BarNumber=",symbol_currentbar,",time[0]=",time[0],",close[0]=",close[0]);

  7. print("BarNumber=",symbol_currentbar-1,"time[1]=",time[1],",close[1]=",close[1]);
  8.       
  9. print("BarNumber=",symbol_currentbar-2,"time[2]=",time[2],",close[2]=",close[2]);
  10.       
  11. print("BarNumber=",symbol_currentbar-3,"time[3]=",time[3],",close[3]=",close[3]);
  12.       
  13. print("BarNumber=",symbol_currentbar-4,"time[4]=",time[4],",close[4]=",close[4]);

  15. end;
  16. end;

最大bar数量（maxbarsback）【强制预留bar数量】对指标无效。大家可以测试一下，在信号上面是有效的，当策略的回溯周期大于强制预留的maxbarsback时会报错。
