請高手幫忙編個指標MACD上穿0軸同時CCI上穿100只在當天K線的最低價處做出符號標記，順便編個選股公式，謝謝

AA:=CROSS("MACD.DIF","MACD.DEA") AND CROSS("MACD.DEA",0) AND CCI>=100;

BB:=DRAWICON(AA,MACD>0,1);

MA1:MA(CLOSE,5);

MA2:MA(CLOSE,10);

MA3:MA(CLOSE,20);

MA4:MA(CLOSE,60);

MA5:MA(CLOSE,120);

MA6:MA(CLOSE,250);

DRAWICON(BB,L*0.97,1);

----------

1）選股公式；

AA:CROSS("MACD.DIF","MACD.DEA") AND CROSS("MACD.DEA",0) AND CCI>=100;

2）放寬條件；

AA:CROSS("MACD.DIF","MACD.DEA") AND CROSS("MACD.DIF",0) AND CCI>=100;
