通达信软件本身没有主力机构资金指标，但可以把你认为的满足条件的主力机构资金编写成指标显示出来这个是可以的。
例如可以在通达信编写个指标公式看到这只个股机构有多少家，持股多少这个是可以做到的。
B. 求通达信用的机构资金公式源码
送你一个我珍藏的机构资金的公式,通达信机构资金流指标公式,源码下面网址里有演示图片.
MA21:MA (CLOSE,21),COLOR00FF00;
MA30:MA(CLOSE,30),COLOR0000FF;
买线:=EMA (C,2);
卖线:=EMA(SLOPE(C,21)*20+C,42);
BUY1:=CROSS(买线,卖线);
SEL:=CROSS(卖线,买线);DRAWTEXT(BUY1,LOW*0.95,'B'),COLORWHITE,LINETHICK5;
DRAWTEXT (SEL,HIGH*1.05,'S'),COLORWHITE,LINETHICK5;
STICKLINE(买线>=卖线,LOW,HIGH,0.1,0),COLORYELLOW;
STICKLINE(买线>=卖线,CLOSE,OPEN,3,3),COLORYELLOW;
STICKLINE(买线<卖线,CLOSE,OPEN,3,3),COLORGREEN;
STICKLINE(买线<卖线,LOW,HIGH,0.1,0),COLORGREEN;
STICKLINE(CROSS(买线,卖线) OR CROSS(卖线,买线),OPEN,CLOSE,2.5,0),COLORWHITE;
主力多空:=C;
V1:=DMA((((HIGH + LOW) + (CLOSE * 2)) / 4),0.9);
HY1:=REF(EMA(V1,3),1);
多空趋势:=MA((CLOSE - HY1) * 10,2);
操盘:STICKLINE(多空趋势>=0 AND 多空趋势>=REF(多空趋势,1),0,多空趋势,3,3),COLORYELLOW;
减仓:STICKLINE(多空趋势>=0 AND 多空趋势< REF(多空趋势,1),0,多空趋势,3,3),COLORYELLOW;
反弹:STICKLINE(多空趋势<0 AND 多空趋势>=REF(多空趋势,1),0,多空趋势,3,3),COLORGREEN;
寻底:STICKLINE(多空趋势<0 AND 多空趋势< REF(多空趋势,1),0,多空趋势,3,3),COLORGREEN;
简要说明：用法同MACD，底背离买入，顶背离卖出
C. 如何编写通达信主力资金进出指标公式
JGV:=(L2_VOL(0,0) - L2_VOL(0,1))*VOL/10000;
DHV:=(L2_VOL(1,0) - L2_VOL(1,1))*VOL/10000;
ZHV:=(L2_VOL(2,0) - L2_VOL(2,1))*VOL/10000;
SHV:=(L2_VOL(3,0) - L2_VOL(3,1))*VOL/10000;
机构资金:EMA(JGV,60)*60/CAPITAL,COLORMAGENTA;
游资资金:EMA(DHV,60)*60/CAPITAL,COLOR3399FF ;
中户版资权金:EMA(ZHV,60)*60/CAPITAL,COLORCYAN;
散户资金:EMA(SHV,60)*60/CAPITAL,COLORGREEN;
D. 通达信可用的 资金博弈指标的 源代码
散户:(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100,LINETHICK1,COLORYELLOW;
中户:(CLOSE-LLV(LOW,10))/(HHV(HIGH,10)-LLV(LOW,10))*100,LINETHICK1,COLORGREEN;
大户内:(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100,LINETHICK1;
机构容:(CLOSE-LLV(LOW,30))/(HHV(HIGH,30)-LLV(LOW,30))*100,LINETHICK2,COLORRED;
