修改股票技术指标，请大神帮忙把这个技术指标，由绿变红改为选股公式！通达信软件可以用的！多谢了？

VAR4:=3*SMA((CLOSE-LLV(LOW,75))/(HHV(HIGH, 75)-LLV(LOW,75))*100, 20, 1)-2*SMA(SMA((CLOSE-LLV(LOW,75))/(HHV(HIGH,75)-LLV(LOW,75))*100, 20, 1), 15, 1);

VAR5:=3*SMA((OPEN-LLV(LOW,75))/(HHV(HIGH, 75)-LLV(LOW,75))*100, 20, 1)-2*SMA(SMA((OPEN-LLV(LOW,75))/(HHV(HIGH,75)-LLV(LOW,75))*100, 20, 1), 15, 1);

VAR6:=100-VAR5;

VAR7:=100-VAR4;

XG:REF(VAR7>=REF(VAR6, 1),1) AND VAR7<REF(VAR6, 1);

哈哈
