根据融大的轨道理论写个选股公式

选股一 ：
1.股价突破中上轨。
2.成交量是昨天的倍量。
3.kdj的J值小于50.
选股二：1.股价突破下轨
2.成交量是昨天的倍量
3.kdJ的J值小于50
源码如下：CC:=ABS((2*CLOSE+HIGH+LOW)/4-MA(CLOSE,20))/MA(CLOSE,20);
DD:=DMA(CLOSE,CC);
上:(1+7/100)*DD,crOSSDOT,COLORGRAY;
下:(1-7/100)*DD,CROSSDOT,COLORGRAY;
中:(上+下)/2,CROSSDOT,COLORF0F000;
危:(1+14/100)*DD,COLORGRAY;
机:(1-14/100)*DD,COLORGRAY;
 

 

CC:=ABS((2*CLOSE+HIGH+LOW)/4-MA(CLOSE,20))/MA(CLOSE,20);
DD:=DMA(CLOSE,CC);
上:=(1+7/100)*DD;
下:=(1-7/100)*DD;
中:=(上+下)/2;
XG:(cross(c,上) or cross(c,下)) and v>2*ref(v,1) and kdj.j<50;
