那个老师把这个公式改成通达信选股公式选出当天收盘收出现红色信号的股票

Question

A7:=C-REF(C,1);
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
SHORT:=7; LONG:=19;
RMA:=EMA(CLOSE,SHORT);
NMA:=EMA(CLOSE,LONG);
UP:DRAWLINE(L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),0);
DOWN:DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0);
买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2))) AND REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1);
趋势区:=IF((EVERY(DOWN>=REF(DOWN,1),1)),4,2)COLOR0000FF,LINETHICK3;
低买:IF(((CROSS(趋势区,2.1))),5,0),STICK,COLORRED,LINETHICK3;
高卖:IF(((CROSS(3.9,趋势区))),-5,0),STICK,COLORFF9150,LINETHICK3;

Answer 1

{ok.收盘收出现红色信号出现}
SHORT:=7;
LONG:=19;
RMA:=EMA(CLOSE,SHORT);
NMA:=EMA(CLOSE,LONG);
DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0);
趋势区:=IF((EVERY(DOWN>=REF(DOWN,1),1)),4,2);
低买:((CROSS(趋势区,2.1)));

追问

老师这个信号会消失吗？

追答

‘DRAWLINE’是通达信特有的划线函数，一旦赋值后，信号就会有漂移，换言之，使用时一定要小心使用。

Answer 2

A7:=C-REF(C,1);
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
SHORT:=7; LONG:=19;
RMA:=EMA(CLOSE,SHORT);
NMA:=EMA(CLOSE,LONG);
UP:=DRAWLINE(L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),0);
DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0);
买进:=(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2))) AND REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1);
趋势区:=IF((EVERY(DOWN>=REF(DOWN,1),1)),4,2);
XG:CROSS(趋势区,2.1);

这个有未来函数，信号会消失。
