飞狐突破下降线选股源码公式：
n:=3;
指數跌幅:(indexc/ref(indexc,20)-1)*100, linethick0;
當日漲幅:(c/ref(c,1)-1)*100, linethick0;
波段漲幅:(c/ref(c,20)-1)*100, linethick0;
A1:=REF(H,N)=HHV(H,2*N+1);
B1:=FILTER(A1,N);
C1:=BACKSET(B1,N+1);
HD:=FILTER(C1,N);
A:=BACKSET(ISLASTBAR,BARSLAST(HD)+1);
HD1:=A>REF(A,1);
B:=BACKSET(HD1,REF(BARSLAST(HD),1)+2);
HD2:=B>REF(B,1);
下降線:LINEVALUE(HD2,H,HD1,H,0,0);
//E:=(ref(h,1)-ref(h,2))<0 and (ref(h,10)-ref(h,20))<0, linethick0;

突破:指數跌幅<-1 and 當日漲幅>1 and 波段漲幅<-5 and CROSS(C,下降線) and vol>ma(v,5) and vol>1000 and c>10,linethick0;
