优化短线精灵指标(通达信)

买卖点一目了然，要说的只有灰线下挖坑区属于超跌区
以下是代码：

VAR1:=(2*CLOSE+HIGH+LOW+OPEN)/5;
VAR2:=LLV(LOW,5);
VAR3:=HHV(HIGH,5);
SK: EMA((VAR1-VAR2)/(VAR3-VAR2)*100,5);
SD: EMA(0.667*REF(SK,1)+0.333*SK,4);
VAR4:=IF(crOSS(SD,SK) AND SK>=60,60,80);
VAR5:=IF(CROSS(SK,20) OR CROSS(SK,SD) AND SK>20,20,10);
买进: VAR5;
卖出: VAR4;
高抛: 80, POINTDOT;
低吸: 20, POINTDOT;
强弱: 50, POINTDOT;
VAR6:=LLV(LOW,55);
VAR7:=HHV(HIGH,34);
VAR8:=EMA((VAR1-VAR6)/(VAR7-VAR6)*100,3);
VAR9:=(SK+VAR8)/2;
VARA:=EMA(0.667*REF(VAR8,1)+0.333*SK,2);
VARB:=EMA(VAR9,5);
VARC:=EMA(0.667*REF(VARB,1)+0.333*VARB,2);
IF(VARB>=40,20,0);

应要求再补两个选股公式：
低位金叉选股：
VAR1:=(2*CLOSE+HIGH+LOW+OPEN)/5;
VAR2:=LLV(LOW,5);
VAR3:=HHV(HIGH,5);
SK:= EMA((VAR1-VAR2)/(VAR3-VAR2)*100,5);
SD:= EMA(0.667*REF(SK,1)+0.333*SK,4);
VAR4:=IF(CROSS(SD,SK) AND SK>=60,60,80);
VAR5:=CROSS(SK,20) OR CROSS(SK,SD) AND SK<40;
买进: VAR5;
-----------------------------------------------
超跌选股：（此公式选出的股慎用，小心选上弱势股一直跌）
VAR1:=(2*CLOSE+HIGH+LOW+OPEN)/5;
VAR2:=LLV(LOW,5);
VAR3:=HHV(HIGH,5);
SK:= EMA((VAR1-VAR2)/(VAR3-VAR2)*100,5);
SD:= EMA(0.667*REF(SK,1)+0.333*SK,4);
VAR4:=IF(CROSS(SD,SK) AND SK>=60,60,80);
VAR5:=IF(CROSS(SK,20) OR CROSS(SK,SD) AND SK>20,20,10);
VAR6:=LLV(LOW,55);
VAR7:=HHV(HIGH,34);
VAR8:=EMA((VAR1-VAR6)/(VAR7-VAR6)*100,3);
VAR9:=(SK+VAR8)/2;
VARA:=EMA(0.667*REF(VAR8,1)+0.333*SK,2);
VARB:=EMA(VAR9,5);
VARC:=EMA(0.667*REF(VARB,1)+0.333*VARB,2);
VARB<40 AND VAR5;
