通达信黑马趋势副图指标公式源码无未来

通达信附图指标黑马趋势，无未来函数，配合主图使用效果更佳，不喜勿喷谢谢！
A1:3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1);  

黑马线:EMA(A1,5),LINETHICK2,COLOR6600FF;  

A2:=(黑马线-REF(黑马线,1))/REF(黑马线,1)*100;  

A3:=EMA(C,5);  

A4:=((C-LLV(L,21))/(HHV(H,21)-LLV(L,21)))*100;  

趋势线: (MA(3*SMA(A4,6,1)-2*SMA(SMA(A4,5,1),5,1),2)),LINETHICK2,COLORYELLOW;  
A5:=(HHV(H,60)-C)/(HHV(H,60)-LLV(L,60))*100;  
DRAWTEXT(FILTER(REF(黑马线,1)>90 AND A2<0,7),黑马线,'跑'),COLOR00FF00;  
DRAWTEXT(CROSS(A1,黑马线)AND 黑马线

DRAWTEXT(CROSS(黑马线,A5)AND 趋势线<80,黑马线,'追涨'
