版主帮忙看下"分时进出"指标为什么无法显示!

分时进出

AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

买量:=IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE<OPEN,AA*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));

卖量:=(IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-AA*(HIGH-LOW),0-VOL/2)))*-1;

差量:=买量-卖量;

进出比:SUM(差量,0)*240/VOL/(BARSSINCE(C)+1);

在副图显示一条直线,版主帮忙修改一下!
