大单流入指标 = VOL * 大单买入量 - 大单卖出量其中，VOL代表股票当日成交量，大单买入量和卖出量需要根据具体的数据源进行定义。

N:=10; AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN)); 买量:=IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE<OPEN,AA*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2)),LINETHICK0; 卖量:=IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-AA*(HIGH-LOW),0-VOL/2)),LINETHICK0,COLORCYAN; 大单动向:(买量+卖量)*10000/FINANCE(7),COLOR00FFFF,NODRAW;这个公式通过计算大单买入量和卖出量的差值，来衡量主力资金的净流入强度。
