【通达信】筹码90%、70%两个成本集中度都小于10的选股公式（已解答：熊市新手2008）

{70%成本集中度}
A1:=COST(85)-COST(15);
B1:=(COST(85)+COST(15))/2;
C70:A1/B1*100;
{90%成本集中度}
A2:=COST(95)-COST(5);
B2:=(COST(95)+COST(5))/2;
C90:A2/B2*100;
10;
15;
************************************************

A1:=COST(85)-COST(15);
B1:=(COST(85)+COST(15))/2;
C70:=A1/B1*100;
A2:=COST(95)-COST(5);
B2:=(COST(95)+COST(5))/2;
C90:=A2/B2*100;

XG:C70<10 AND C90<10;是两个指标，上面的是副图，下面的才是选股的：
