大智慧经验公式“主力仓位”

这公式不用什么分笔交易数据，根据经验写出来的，与那些分笔数据弄出来的图十分接近，感觉它或许更可靠一点

{主力仓位}

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,P)/sum(v,P)*1000,LINETHICK1;
 dt:=ZL-ref(ZL,1);
