XG:=REF(MA(C,5),1)<MA(C,5) AND REF(MA(C,10),1)<MA(C,10) AND REF(MA(C,20),1)<MA(C,20)
AND REF(MA(C,30),1)<MA(C,30) AND EVERY(C>MA(C,30),20);
XG2:=ABS(MA(C,5)-MA(C,10)>REF(MA(C,5)-MA(C,10),1)) AND
ABS(MA(C,5)-MA(C,20)>REF(MA(C,5)-MA(C,20),1)) AND
ABS(MA(C,5)-MA(C,30)>REF(MA(C,5)-MA(C,30),1)) AND
EVERY(C>MA(C,30),20);
XG3:=EVERY(C>MA(C,30),20);
X1:FILTER(XG,5);
X2:FILTER(XG2,5);
X3:FILTER(XG3,5);

{X1,X2 是原来的条件，二选一，X3是现条件。};
