A、指标说明：
｛容维中华方圆图信号为"▲，◆，□，●"等，图中的均线趋势线也是容维原码的；多空转向的的信号设置为"蓝★卖 红★买"。当出现了白色 □ 提示后，又接着出现红▲图或者红★图甚至一起出现时，就应该特别研究下是否该进场了；当出现了绿色 ● 圆顶图提示后，应该开始减仓了，如果有接着出现了蓝★卖出信号，则不用犹豫了，清仓吧。｝

C、选股公式：
一、
{红▲、红★同时出现选股}
X:=EMA(((SLOPE(CLOSE,21) * 20) + CLOSE),68);
Y:=EMA(CLOSE,10);
红▲:=CROSS(Y,X);
c1:=(CLOSE+LOW+HIGH)/3;
c2:=EMA(c1,6);
c3:=EMA(c2,5);
红★:=CROSS(c2,c3);
红▲ and 红★;

二、
{白色□选股}
VAR1:=LLV(LOW,21);
VAR2:=HHV(HIGH,21);
AK1:=EMA((((CLOSE - VAR1) / (VAR2 - VAR1)) * 100),5);
AK:=EMA((((CLOSE - VAR1) / (VAR2 - VAR1)) * 50),13);
AB:=CROSS(AK1,AK);
VAR3:=LLV(LOW,55);
VAR4:=HHV(HIGH,34);
VAR5:=EMA((((CLOSE - VAR3) / (VAR4 - VAR3)) * 100),3);
VAR6:=((AK + VAR5) / 2);
VAR8:=EMA(VAR6,5);
BB:=EMA(((0.667 * REF(VAR8,1)) + (0.333 * VAR8)),2);
BB1:=(CROSS(AK1,BB) AND (BB < 30));
CD:=(BB1 * 0.6);

白色□:AB =1;

三、
{红▲选股}
X:=EMA(((SLOPE(CLOSE,21) * 20) + CLOSE),68);
Y:=EMA(CLOSE,10);
红▲:CROSS(Y,X);

四、
{红★选股}
c1:=(CLOSE+LOW+HIGH)/3;
