老師您好！

　　請幫忙寫一個ＳＬＯＷＫＤ上穿５０時聲音報警．另外寫一個ＳＬＯＷＫＤ金叉和死叉聲音報警．謝謝！

該指標中K D兩個值，您要的是哪一個上穿50報警？

老師:是D值謝謝

RSV:= (CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
FASTK:=SMA(RSV,3,1);
K:=SMA(FASTK,3,1);
D:=SMA(K,M3,1);
PLAYSOUND(CROSS(D,50),'A');
PLAYSOUND(CROSS(K,D),'J');

僅供參考；

老師!請問如果要將K上穿D和K下穿D分開表達是不是這樣寫:
RSV:= (CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
FASTK:=SMA(RSV,3,1);
K:=SMA(FASTK,3,1);
D:=SMA(K,M3,1);
PLAYSOUND(CROSS(K,D),);

RSV:= (CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
FASTK:=SMA(RSV,3,1);
K:=SMA(FASTK,3,1);
D:=SMA(K,M3,1);
PLAYSOUND(CROSS(D,K),);
