控盘线:MA(EMA(WINNER(C),3),40)*20,COLORGRAY,LINETHICK3;
红色启动埋伏:(EMA(IF(LOW<=LLV(LOW,30),(SMA(ABS(LOW-REF(LOW,1)),30,1))/(SMA(MAX(LOW-REF(LOW,1),0),30,1)),0),3))*(10),COLORRED,LINETHICK2;
(CROSS(控盘线,红色启动埋伏) AND 控盘线<10)*10,COLORGREEN,LINETHICK2;
红色启动埋伏说明有主力进入,但不是买点,买点在控盘线上穿红色启动埋伏线或者控盘线变黄,控盘线由黄变灰为短期卖点,下穿红色启动埋伏线为出场时机。
