用于免费数据的(主力持仓).请老师做个从绿变红的选股公式. 谢谢! VAR1:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN)); 主买:=IF(CLOSE>OPEN,VAR1*(HIGH-LOW),IF(CLOSEOPEN,VAR1*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE0,ZL,ZL+DT,1,0),COLORRed; STICKLine(DT<0,ZL+DT,ZL,1,0),COLORGreen; DRAWTEXTABS(0,0,'【主力持仓】'),colorffffff,LINETHICK1;

编写方法：

&nbsp;VAR1:=vol/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

主买:=IF(CLOSE>OPEN,VAR1*(HIGH-LOW),IF(CLOSE<OPEN,VAR1*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));

主卖:=IF(CLOSE>OPEN,VAR1*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,VAR1*(HIGH-LOW),VOL/2));

主力买入量:=(主买*0.5+主卖*0.1)/2;

ZL:=SUM(主力买入量,60)/SUM(V,60)*100;

DT:=ZL-REF(ZL,1);

 

REF(DT,1)<0 AND DT>0;
