原理解析：
A0赋值:(2*C+H+L)/4
均线赋值:A0的3日简单移动平均>REF(A0的3日简单移动平均,1)
A1赋值:(收盘价-7日内最低价最低值)/(7日内最高价最高值-7日内最低价最低值)*100
A2赋值:EMA(C计算的获利盘比例*100,5)
A3赋值:MA(SMA(C-1日前的C,3,1)/SMA(H-1日前的C,3,1),3)*100
A1的6日[1日权重]移动平均
输出D:K的3日简单移动平均,COLORFF0000,LINETHICK1
输出J:3*K-2*D,LINETHICK1
A4赋值:SMA(C-2日前的C和0较大值,6,1)/SMA(C-2日前的C的绝对值,6,1)*100
A5赋值:MA(3*SMA((C-21日内L最低值)/(21日内H最高值-21日内L最低值)*100,5,1)-2*SMA(SMA((C-21日内L最低值)/(21日内H最高值-21日内L最低值)*100,5,1),3,1),3)
输出低吸:IF(A4上穿14 OR A5>1日前的A5 AND K上穿A2AND K<40,10,0)
IF(A2>80 AND 95上穿K,85,100)
输出跌幅较大:K<5 AND 3日内C最低值/20日内C最高值<0.8,COLOR00FF00
当满足条件跌幅较大时,在0和30之间画柱状线
A6赋值:统计2日满足K上穿A2的天数=1 AND K上穿A5AND A5/1日前的A5>0.9 AND K<50
A7赋值:K上穿DAND D<10 OR K上穿DAND K上穿A5AND D<18
{DRAWTEXT(FILTER((A6 OR A7)AND K>1日前的K,5)AND 均线 ,D,'金叉')
DRAWTEXT(D上穿KAND A5上穿KAND D>85,D,'死叉')
DRAWTEXT(FILTER(K>1日前的KAND (K上穿10OR K上穿A2)AND 统计3日满足A4<14的天数>=1,3),15,'虎口拔牙')
输出}无限风光:A2>85 AND K>85 OR A2>90 OR K>90,LINETHICK0,COLORFFFF00
STICKLINE(无限风光,A2和K较大值,100,6,1),COLORFFFF00
DRAWICON(A3上穿-300AND K<10,5,1)
A8赋值:上次1日前的K上穿D距今天数
二次金叉赋值:(A8<15 AND D<50 AND K>A8+1日前的K AND K上穿DAND A5<60)
当满足条件二次金叉 AND 均线时,在K和'二次金叉'位置书写文字
}A9赋值:2日内C最低值当满足条件二次金叉 AND A9时,在K和'底背离'位置书写文字
{DRAWTEXT(LONGCROSS(J,K,7)AND CROSS(J,A2)AND A2<30 AND A2>1日前的A2,K,'穿三线')
}{DRAWTEXT(84上穿A4AND K上穿A4,90,'虎口脱险'),COLOR00FF00
}A10:=MA((A0-MA(A0,13))/(0.15*AVEDEV(A0,13)),3)
DRAWICON(A10上穿-15AND J>1日前的J,5,1)
DRAWICON(20上穿A10,100,2)
输出卖点准备: IF(D上穿K AND K>85,70,100),LINETHICK1,COLORSTICK
输出买点准备: IF(K上穿D AND K<10,35,-0.6),LINETHICK1,COLOR00FF00
