股市轮回主要是底部筑底，启动拉升，回踩关键点位，再次筑底拉升，然后卖出获利，其中筑底和回踩关键点位是两个重要的关注点，是介入点的操作信号，具体的形态分析可以通过股票公式中的指标源码进行分析。

　　【底部介入指标】

　　讲解的是通过量能的买卖以及进出量的变化关系，选择买卖点以及短线介入的点位，具体的源码公式如下：

　　AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

　　买量:=IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE

　　卖量:=IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE

　　进出量:=买量+卖量,COLOR00FFFF;

　　五日内净流入:=SUM(进出量,5),LINETHICK1,COLORLIBLUE;

　　N:=9;M:=14;N1:=6;

　　TYP := (HIGH + LOW + CLOSE)/3;

　　R9+(3*R12-2*(EMA(R12,10)));

　　R16:=(HIGH+LOW+CLOSE)/3;

　　R17:=(R16-MA(R16,34))/(0.015*AVEDEV(R16,34));
