将机构买盘大于机构卖盘2倍修改为盘中预警公式

编写要求：

这是源代码a1:=(VOL/CLOSE)/3;a2:=SUM((IF(((a1>40) AND (CLOSE>(REF(CLOSE,1)))),a1,0)),0);a3:=SUM((IF(((a1>40) AND (CLOSE<(REF(CLOSE,1)))),a1,0)),0);a4:=SUM((IF(((a1<40) AND (CLOSE>(REF(CLOSE,1)))),a1,0)),0);a5:=SUM((IF(((a1<40) AND (CLOSE<(REF(CLOSE,1)))),a1,0)),0);a6:=((a2+a3)+a4)+a5;a7:=IF((BARSTATUS=2),((100*a2)/a6),0);a8:=((IF((BARSTATUS=2),((100*a3)/a6),0)));a9:=((IF((BARSTATUS=2),((100*a4)/a6),0)));a10:=((IF((BARSTATUS=2),((100*a5)/a6),0)));机构买盘:(a2),linethick3,ColorFF55FF;机构卖盘:(a3),linethick3,ColorFFFF55;散户买盘:(a4),Color5555FF;散户卖盘:(a5),Color55FF55;DRAWTEXTREL(1003,870,'机构买盘'),linethick2,ColorFF55FF;DRAWTEXTREL(1003,570,'机构卖盘'),linethick2,ColorFFFF55;DRAWTEXTREL(1003,320,'散户买盘'),linethick2,Color5555FF;DRAWTEXTREL(1003,50,'散户卖盘'),linethick2,Color55FF55;if ((BARSTATUS=2) ) Then DRAWTEXTREL(1020,750,''+FLOOR(a7)+'%'),linethick2,ColorFF55FF;if ((BARSTATUS=2) ) Then DRAWTEXTREL(1020,460,''+FLOOR(a8)+'%'),linethick2,ColorFFFF55;if ((BARSTATUS=2) ) Then DRAWTEXTREL(1020,200,''+FLOOR(a9)+'%'),linethick2,Color5555FF;if ((BARSTATUS=2) ) Then DRAWTEXTREL(1020,-50,''+FLOOR(a10)+'%'),linethick2,Color55FF55;在此基础上如果可以加即时量比大于1.5就更好了我在此先谢过老师了·

解答：

a1:=(VOL/CLOSE)/3;
