跟庄分时指标改选股预警公式_股票入门

跟庄分时指标，请老师按思路改选股预警三公式：

1机买上穿机卖选股预警！

2机买先后上穿散买散卖选股预警！

3机卖=0，散买散卖下跌，机买先后上穿散买散卖选股

很感谢踏雪无痕的回复！

解答如下：

1.

A1:=(DVOL/C)/2;

A2:=SUM(IF(A1>100 AND

CLOSE>REF(CLOSE,1),A1,0),0);

A3:=SUM(IF(A1>100 AND

CLOSE<REF(CLOSE,1),A1,0),0);

A4:=SUM(IF(A1<100 AND

CLOSE>REF(CLOSE,1),A1,0),0);

A5:=SUM(IF(A1<100 AND

CLOSE<REF(CLOSE,1),A1,0),0);

A6:=A2+A3+A4+A5;

机买:=(A2/A6)*100;

机卖:=(A3/A6)*100;

CROSS(机买,机卖);

2.

A1:=(DVOL/C)/2;

A2:=SUM(IF(A1>100 AND

CLOSE>REF(CLOSE,1),A1,0),0);

A3:=SUM(IF(A1>100 AND

CLOSE<REF(CLOSE,1),A1,0),0);

A4:=SUM(IF(A1<100 AND

CLOSE>REF(CLOSE,1),A1,0),0);

A5:=SUM(IF(A1<100 AND

CLOSE<REF(CLOSE,1),A1,0),0);

A6:=A2+A3+A4+A5;

机买:=(A2/A6)*100;

散买:=(A4/A6)*100;

散卖:=(A5/A6)*100;

CROSS(机买,散买)

AND CROSS(机买,散卖);
