单笔数差！图标出现时为买入时机：
0,LINETHICK1,ColorA6A6A6;
单差:sum(ORDERNUM(2,0)-ORDERNUM(1,0),0),LINETHICK1,Colorred;
笔差:sum(TRANSACTNUM(1,0)-TRANSACTNUM(2,0),0),LINETHICK1,Color1F7BFD;
金叉:=cross(笔差,单差);
DRAWICON(金叉,单差*0.8,2),LINETHICK1,Colorwhite;
分时DDX：
DDX:(ordervol(1,2)-ordervol(2,2))/capital*100,colorstICK,LINETHICK2;
ZDDDX:=(transactvol(1,2)-transactvol(2,2))*100/capital;
主动DDX:SUM(ZDDDX,0),Color87BEFF;
DDX累积:SUM(ddx,0),ColorYellow;
