求通达信选股公式

用macd的dif曲线为副图主线，在曲线上升的时候曲线显示红色，dif曲线上升途中第一次出现成交量达到50天量在曲线上标记买,dif减去dea的值比前一天小的时候标记卖，我取了一段简单涂了下，基本是这个意思，再麻烦解释下出现买的标记时如何选股谢谢,

这是你说的意思的指标公式

DIF:EMA(CLOSE,12)-EMA(CLOSE,26);

DEA:EMA(DIF,9);

MACD:(DIF-DEA)*2,COLORSTICK;

IF(DIF>REF(DIF,1) AND DIF>DEA AND DIF>0,DIF,DRAWNULL),COLORRED,LINETHICK2;

IF(DIF<REF(DIF,1) AND DIF>DEA AND DIF>0,DIF,DRAWNULL),COLORGREEN,LINETHICK2;

X1:=DIF>0 AND DIF>REF(DIF,1) AND DIF>DEA;

X2:=DIF<REF(DIF,1) AND DIF>0 AND MACD<REF(MACD,1) AND DIF>DEA;

DRAWTEXT((REF(BARSLAST(X1 AND REF(X1,1)=0)<BARSLAST(CROSS(V,MA(V,50))),1)=1 AND REF(V<MA(V,50),BARSLAST(X1 AND REF(X1,1)=0)) AND CROSS(V,MA(V,50))) OR (X1 AND REF(X1,1)=0 AND V>MA(V,50)),DIF*1.1,'买')COLORYELLOW;

DRAWTEXT(X2 AND REF(X2,1)=0,DIF*1.1,'卖')COLORWHITE;

下面是条件选公式

DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);

DEA:=EMA(DIF,9);

MACD:=(DIF-DEA)*2;

X1:=DIF>0 AND DIF>REF(DIF,1) AND DIF>DEA;

XG:(REF(BARSLAST(X1 AND REF(X1,1)=0)<BARSLAST(CROSS(V,MA(V,50))),1)=1 AND REF(V<MA(V,50),BARSLAST(X1 AND REF(X1,1)=0)) AND CROSS(V,MA(V,50))) OR (X1 AND REF(X1,1)=0 AND V>MA(V,50));

追问

你好公式设计的基本满意，只是DIF值范围要包括0轴下方，在0轴下方也有上行的趋势，dif值域取全部，截了个图这个图里面的卖是0轴下方的情况，

需要修改下，公式设计的基本满意，麻烦你再修改下这个公式谢谢

DEA:EMA(DIF,9);
MACD:(DIF-DEA)*2,COLORSTICK;
IF(DIF>REF(DIF,1),DIF,DRAWNULL),COLORRED,LINETHICK2;
IF(DIFREF(DIF,1);
X2:=DIFMA(V,50)),DIF*1.1,'买')COLORYELLOW;

你好，卖点那里滞后了一些，我截了图麻烦你看下，红色箭头标出来的两个应该标记卖的地方没有标记，这两处dif-dea的值比前一天减小了应该卖出标记，麻烦再看看修改下谢谢！
