請高手把這個指標改成預警公式，謝謝了，真的急用中…………

A7:=C-REF(C,1);

A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);

SHORT:=7;?LONG:=19;

RMA:=EMA(CLOSE,SHORT);

NMA:=EMA(CLOSE,LONG);

UP:=DRAWLINE(L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),0);

DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0);

徐莨蘋買進:(LLV(A8,2)=LLV(A8,7)?AND?COUNT(A8<0,2)?AND?CROSS(A8,MA(A8,2)))?AND?REF(DOWN,1)<REF(DOWN,2)?AND?UP>REF(DOWN,1);
