请教师帮写分时图强势的数据信号出現后维持超过200分鐘不消退的选股公式。

A1:=(VOL/CLOSE)/3;

A2:=SUM((IF(((A1>0.29) AND (CLOSE>(REF(CLOSE,1)))),A1,0)),0);

A3:=SUM((IF(((A1>0.29) AND (CLOSE<(REF(CLOSE,1)))),A1,0)),0);

DIF:=(EMA(CLOSE,380)-EMA(CLOSE,800))*50;

DEA:=EMA(DIF,40);

MACD:=(DIF-DEA)*5;

DIF>=DEA and MACD>0 and A2>A3;

解释以下：

A1:=(VOL/CLOSE)/3;

A2:=SUM((IF(((A1>0.29) AND (CLOSE>(REF(CLOSE,1)))),A1,0)),0);

A3:=SUM((IF(((A1>0.29) AND (CLOSE<(REF(CLOSE,1)))),A1,0)),0);

DIF:=(EMA(CLOSE,380)-EMA(CLOSE,800))*50;

DEA:=EMA(DIF,40);

MACD:=(DIF-DEA)*5;

AA:=DIF>=DEA and MACD>0 and A2>A3;

LAST(AA)>=200;{剖析周期时间：分时图}
