网友求助：
A1:=MAX(MA(C,20),MA(C,30));
A2:=MAX(A1,MA(C,60));
A3:=MAX(A2,MA(C,120));
A4:=MAX(A3,MA(c,250));
B1:=MIN(MA(C,20),MA(C,30));
B2:=MIN(B1,MA(C,60));
B3:=MIN(B2,MA(C,120));
B4:=MIN(B3,MA(C,250))
(A4-B4)/A4<=0.03;
A2:=MAX(A1,MA(C,60));
A3:=MAX(A2,MA(C,120));
A4:=MAX(A3,MA(c,250));
B1:=MIN(MA(C,20),MA(C,30));
B2:=MIN(B1,MA(C,60));
B3:=MIN(B2,MA(C,120));
B4:=MIN(B3,MA(C,250))
(A4-B4)/A4<=0.03;
解答如下：
A1:=MAX(MA(C,20),MA(C,30));
A2:=MAX(A1,MA(C,60));
A3:=MAX(A2,MA(C,120));
A4:=MAX(A3,MA(C,250));
B1:=MIN(MA(C,20),MA(C,30));
B2:=MIN(B1,MA(C,60));
B3:=MIN(B2,MA(C,120));
B4:=MIN(B3,MA(C,250));
XG:(A4-B4)/A4<=0.03;
A2:=MAX(A1,MA(C,60));
A3:=MAX(A2,MA(C,120));
A4:=MAX(A3,MA(C,250));
B1:=MIN(MA(C,20),MA(C,30));
B2:=MIN(B1,MA(C,60));
B3:=MIN(B2,MA(C,120));
B4:=MIN(B3,MA(C,250));
XG:(A4-B4)/A4<=0.03;
