经济常识：并线开花选股

　　a:=max(ma(c,120),ma(c,250))
cross(ma(c,20),a) and v>ref(v,1)

　　是不是这个三线开花,看源码下面网址里的图片,对照一下.

　　求通达信三线开花的盘中预警公式

　　哪三条线说清楚 。我估计你也是看到网上的三线开花主图了。是不是这个主图。附三个选股指标，一并送你：
一、主图指标：
ma20:ma(c,20),colorwhite,linethick2;
ma120:ma(c,120),colorffcccc,linethick2;
ma250:ma(c,250),colorffcc66,linethick2;
乖离线:=((c-ref(ma20,1))/20+ma20)*1.20;
tt1:=cross(ma20,ma120) and cross(ma20,ma250) and v>ref(v,1);
tt2:=ma20>ref(ma20,2) and v>ref(v,1) and cross(c,ma20);
STICKLINE(TT1,l,l-0.09,4,0),coloryellow;
DRAWTEXT(TT1,l-0.13,金叉),coloryellow;
STICKLINE(cross(c,ma120) and cross(c,ma250) and cross(c,ma20),l,l-0.09,4,0),coloryellow;
DRAWTEXT(cross(c,ma120) and cross(c,ma250) and cross(c,ma20),l-0.13,并线开花),coloryellow;
STICKLINE(tt2,l,l-0.09,4,0),coloryellow;
DRAWTEXT(tt2,l-0.13,买点1),coloryellow;
STICKLINE(cross(c,乖离线;
DRAWTEXT(cross(c,乖离线;
STICKLINE(ma250>=ref(ma250,1) and ma20>=ref(ma20,1) and cross(c,ma250),l,l-0.09,4,0),colorffcc66;
DRAWTEXT(ma250>=ref(ma250,1) and ma20>=ref(ma20,1) and cross(c,ma250),l-0.13,牛象),colorffcc66;

Va1:=(C+v3-v1+macd);
Va4:=(C+v2-v1+macd);
短线),linethick2,Coloryellow;
二、下面是三个选股指标：
MA20:=MA(C,20);
MA120:=MA(C,120);
MA250:=MA(C,250);
乖离线:=((C-REF(MA20,1))/20+MA20)*1.20;
买点1:CROSS(MA20,MA120) AND CROSS(MA20,MA250) AND V>REF(V,1);
----------------------------------------
MA20:=MA(C,20);
MA120:=MA(C,120);
买点2:MA120>=REF(MA120,1) AND CROSS(C,MA20) AND CROSS(C,MA120) AND V>REF(V,1);
========================
MA20:=MA(C,20);
MA120:=MA(C,120);
MA250:=MA(C,250);
并线开花:CROSS(C,MA120) AND CROSS(C,MA250) AND CROSS(C,MA20);

　　请高手老师帮忙编一个60 120 180 250四线开花的选股公式。谢谢！

　　c1:=cyc.cyc1;
c2:=cyc.cyc2;
c3:=cyc.cyc3;
c4:=cyc.cyc∞;
c>o
&&
cross(c,c1)
&&
cross(c,c2)
&&
cross(c,c3)
&&
cross(c,c4);

　　“问财选股”输入     月线轴上金叉    即可，还可以改变选股条件进行选股，用法类似。

　　能不能编写一个MACD周线和月线同时在零轴上金叉的选股公式呢

　　不要炒股了，那都是骗你钱的。
