将坚定买入指标改成选股公式
编写要求：
把下面图同时出现坚定和买入选出来。坚定买入指标如下： VAR1:=BACKSET(REF(HIGH,2)=HHV(HIGH,5),3); VAR2:=CROSS(VAR1,0.9); VAR3:=BACKSET(REF(LOW,2)=LLV(LOW,5),3); VAR4:=CROSS(VAR3,0.9); VAR5:=IF(VAR2,HIGH,IF(VAR4,LOW,0)); VAR6:=BACKSET(REF(HIGH,2)=HHV(HIGH,5) AND LOWREF(LOW,1) AND HIGH>REF(HIGH,1),3); VAR8:=BACKSET(REF(HIGH,2)=HHV(HIGH,5) AND HIGHREF(LOW,1) AND REF(LOW,1)>REF(LOW,2) AND REF(HIGH,1)REF(LOW,1) AND HIGH>REF(HIGH,1),3); VARA:=BACKSET(REF(LOW,2)=LLV(LOW,5) AND LOWREF(LOW,1) AND REF(LOW,1)>REF(LOW,2) AND REF(HIGH,1)
公式在线网解答：
改不出来。“BACKSET”---马后炮神将在此，不能实现。要不你试试看会不会出信号？
{买入}
VAR1:=BACKSET(REF(HIGH,2)=HHV(HIGH,5),3);
VAR2:=CROSS(VAR1,0.9);
VAR3:=BACKSET(REF(LOW,2)=LLV(LOW,5),3);
VAR4:CROSS(VAR3,0.9);
