求：前17天D大于80，今天筹码空间小于5选股公式？
筹码空间源码：
筹码空间:IF(WINNER(CLOSE),WINNER(CLOSE)*100,20),VOLSTICK;
VAR1:=LLV(LOW,21);
VAR2:=HHV(HIGH,21);
K: EMA((CLOSE-VAR1)/(VAR2-VAR1)*100,6),COLORRED,LINETHICK2;
D: EMA(0.667*REF(K,1)+0.333*K,2),COLORCYAN,LINETHICK2;
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);
趋势:EMA(0.667*REF(VAR8,1)+0.333*VAR8,2),COLORFF00AA,LINETHICK2;
DRAWICON(LONGCROSS(D,K,0.1),D,2);
DRAWICON(LONGCROSS(K,D,0.1),K,1);
 

 

解答如下：

筹码空间:=IF(WINNER(CLOSE),WINNER(CLOSE)*100,20);
VAR1:=LLV(LOW,21);
VAR2:=HHV(HIGH,21);
K:=EMA((CLOSE-VAR1)/(VAR2-VAR1)*100,6);
D:=EMA(0.667*REF(K,1)+0.333*K,2);
REF(筹码空间<5 AND D>80,17);
