有請老師怎么寫(MACD穿越取值問題）

DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:EMA(DIFF,9);

OO:=VALUEWHEN(CROSS(DIFF,0),O);//DIFF上穿0軸時 K線的開盤價
CC:=VALUEWHEN(CROSS(DIFF,0),C);//DIFF上穿0軸時 K線的收盤價

僅供參考！

DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:EMA(DIFF,9);

OO:=VALUEWHEN(CROSS(DIFF,0),O);//DIFF上穿0軸時 K線的開盤價
CC:=VALUEWHEN(CROSS(DIFF,0),C);//DIFF上穿0軸時 K線的收盤價

OO1:=VALUEWHEN(CROSS(0,DIFF),O);//DIFF下穿0軸時 K線的開盤價
CC1:=VALUEWHEN(CROSS(0,DIFF),C);//DIFF下穿0軸時 K線的收盤價
