解答如下：

当日成交:=amount*BIGORDER(1,2)/10000-amount*BIGORDER(2,2)/10000;

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

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

HSL:=((XVL/40)/1.15);

主买:=SUM(HSL,10);

主卖:=EMA(主买,6);

量柱:=主买-主卖;

XG:CROSS(量柱,0)and 当日成交>150;
