这是一个成交量的公式，请老师做个选股公式。要求：出现红箭头当天的成交量柱状，要大于上次出现红箭头的成交量柱状。柱状也就是指的筹码空间。源码如下：
筹码空间:IF(WINNER(CLOSE),WINNER(CLOSE)*100,20),VOLSTICK;
TX80:80,POINTDOT, COLORYELLOW;
DX20:20,POINTDOT, COLORGREEN;
VAR1:=LLV(LOW,21);
VAR2:=HHV(HIGH,21);
K: EMA((CLOSE-VAR1)/(VAR2-VAR1)*100,6),COLORRED;
D: EMA(0.667*REF(K,1)+0.333*K,2),COLORGREEN;
VAR3:=LLV(LOW,55);
VAR4:=HHV(HIGH,34);
VAR5:=EMA((CLOSE-VAR3)/(VAR4-VAR3)*100,3);
VAR6:=(K+VAR5)/2;
VAR7:=EMA(0.667*REF(VAR5,1)+0.333*K,2);
VAR8:=EMA(VAR6,5);
VAR9:EMA(0.667*REF(VAR8,1)+0.333*VAR8,2);
DRAWICON(LONGCROSS(D,K,0.1),D,2),COLORRED;
DRAWICON(LONGCROSS(K,D,0.1),K,1),COLORGREEN;
