同花顺LEVEL-2 BBD是什么意思

       是个公式,BBD源码如下,演示下面网址里有

       p2:=SUBSAMEDAY(&BIGBUYCOUNT2);

       b2:=SUBSAMEDAY(&WAITBUYCOUNT2);

       p3:=SUBSAMEDAY(&BIGBUYCOUNT1);

       b3:=SUBSAMEDAY(&WAITBUYCOUNT1);

       n2:=SUBSAMEDAY(&BIGSELLCOUNT2);

       m2:=SUBSAMEDAY(&WAITSELLCOUNT2);

       n3:=SUBSAMEDAY(&BIGSELLCOUNT1);

       m3:=SUBSAMEDAY(&WAITSELLCOUNT1);

       主力量比:SUM(p2+b2+p3+b3-n2-m2-n3-m3,0)/V*;

       特单量比:SUM(p3+b3-n3-m3,0)/V*;

       大单量比:SUM(p2+b2-n2-m2,0)/V*;

       主被量比:(SUM(p2+p3-n2-n3,0)-SUM(b2+b3-m2-m3,0))/V*;
