现在优化如下：
1、可选择交易额（类型1）和交易量（类型2）。其中：成交额单位为“万元”；成交量单位为“手”。
2、加入名义换手率、实际换手率、历史换手衰减系数及均线等多项元素，完全可代替系统vol或amo公式。
类型选择:=1;
极值周期:=6;
显示标线:=0;
显示均线:=1;
均线周期1:=5;
均线周期2:=10;
买额:=L2_AMO(0,0)+L2_AMO(1,0),NODRAW;
卖额:=L2_AMO(0,1)+L2_AMO(1,1),NODRAW;
买量:=L2_VOL(0,0)+L2_VOL(1,0),NODRAW;
卖量:=L2_VOL(0,1)+L2_VOL(1,1),NODRAW;
成交:IF(类型选择=1,AMO/10000,VOL),NODRAW,COLORYELLOW;
主力:IF(类型选择=1,(买额+卖量)/20000,(买量+卖量)/2),COLORRED,NODRAW;
净值:IF(类型选择=1,(买额-卖额)*0.0001,买量-卖量),NODRAW,COLORWHITE;
买比:IF(类型选择=1,买额/AMO*100,买量/VOL*100),NODRAW,COLORRED;
卖比:IF(类型选择=1,卖额/AMO*100,卖量/VOL*100),NODRAW,COLORGREEN;
净比:买比-卖比,NODRAW,COLORMAGENTA;
成交增幅:(成交-REF(成交,1))/REF(成交,1)*100,NODRAW;
主力增幅:(主力-REF(主力,1))/REF(主力,1)*100,NODRAW;
主力活跃度:净值/REF(成交,1)*100,NODRAW;
名义换手:VOL/CAPITAL*100,NODRAW,COLORWHITE;
实际换手:VOL/FINANCE(46)*10000,NODRAW,COLORYELLOW;
衰减系数:1/(1-(FINANCE(46)/(CAPITAL*100))),NODRAW,COLORRED;

NOTEXT2:IF(显示标线=1,HHV(成交,极值周期)/2,DRAWNULL),COLORWHITE;
