原理解析：
A赋值:34日内L最低值
XD赋值:SMA(L-1日前的L的绝对值,34,1)
CD赋值:SMA(L-1日前的L和0较大值,34,2)
如果L<=A返回XD/CD否则返回-3
输出抢反弹:收盘买<0 AND 收盘买>1日前的收盘买 AND REF(EVERY(收盘买<1日前的收盘买,3),1),画黄色
RSV赋值:(收盘价-9日内最低价最低值)/(9日内最高价最高值-9日内最低价最低值)*100
RSV的3日[1日权重]移动平均
K的3日[1日权重]移动平均
J赋值:3*K-2*D
X2赋值:2日内J最低值=8日内J最低值
输出B:CROSS(J,1日前的J+0.01) AND X2 AND J<20 AND 收盘买<0 AND 收盘买>1日前的收盘买,COLORRED
B2:CROSS(J,1日前的J+0.01) AND X2 AND J<20,COLORMAGENTA
当满足条件B2时,在0.35和'★关注★'位置书写文字
B3:=抢反弹 AND 1日前的B2
DRAWBAND(B2,RGB(255,100,30),B3,RGB(255,20,20))
当满足条件B3时,在0.45和'★不买更后悔★'位置书写文字
B4:=抢反弹 AND 1日前的B2OR 2日前的B2
当满足条件B3时,在0.35和'★反弹确认★'位置书写文字
当满足条件B3时,在0和0.43之间画柱状线
当满足条件B时,在0和0.43之间画柱状线
当满足条件B时,在0.35和'★不买后悔★'位置书写文字
B8:=REF((CROSS(J,REF(J+0.01,1)) AND X2 AND J<20),2) AND 抢反弹
当满足条件B8时,在0.8和'★阶段底部确认★'位置书写文字
DRAWBAND(B2,RGB(255,100,50),B8,RGB(255,30,30))
