把“秘密买卖点”改写为选股公式

编写条件：

这个指标是原来在论坛里看到的（谢谢原作者），源码如下： {N 1 10 7} 顶:80,COLORGREEN; 底:20,COLORRED; 熊市顶:70; LC:=REF(CLOSE,1); 趋势:SMA(MAX(CLOSE-LC,0),N,1)/SMA(ABS(CLOSE-LC),N,1)*100,COLORYELLOW; 底1:IF(趋势<20,40,20),COLORRED; 卖出1:IF(趋势>80,60,80),COLORGREEN; 买1:STICKLINE(FILTER(REF(趋势,1)<20 AND 趋势>REF(趋势,1),5),20,40,2,0),COLORRED; 趋势↓:STICKLINE(FILTER(REF(趋势,1)>80 AND 趋势REF(趋势,1),5),40 ,'买入1' ),COLORRED; DRAWTEXT(FILTER(REF(趋势,1)>80 AND 趋势REF(趋势,1),5),20,40,2,0) ,COLORMAGENTA; DRAWTEXT(FILTER(REF(趋势,1)<30 AND 趋势>REF(趋势,1),5),40 ,'买入2' ),COLORMAGENTA;

编写方法：

&nbsp;N:=7;

LC:=REF(CLOSE,1);

趋势:=SMA(MAX(CLOSE-LC,0),N,1)/SMA(ABS(CLOSE-LC),N,1)*100,COLORYELLOW;

xg1:REF(趋势,1)<20 AND 趋势>REF(趋势,1);

 

N:=7;

LC:=REF(CLOSE,1);

趋势:=SMA(MAX(CLOSE-LC,0),N,1)/SMA(ABS(CLOSE-LC),N,1)*100,COLORYELLOW;

xg2:REF(趋势,1)<30 AND 趋势>REF(趋势,1);
