将大智慧短期压力支撑画线指标改成通达信的

编写要求：

input: N(5,1,100); A1:=ref(h,N)=hhv(h,2*N+1); B1:=filter(A1,N); C1:=backset(B1,N+1); D1:=filter(C1,n);{高点} A2:=ref(l,N)=llv(l,2*N+1); B2:=filter(A2,N); C2:=backset(B2,N+1); D2:=filter(C2,N);{低点} E1:=(ref(llv(l,2*N),1)+ref(hhv(h,2*N),1))/2; E2:=(h+l)/2;{高低点出现在同一K线上时可作取舍} H1:=(D1 AND not(D2 AND E1>=E2)) OR barstatus=2 OR barscount(c)=1; L1:=(D2 AND not(D1 AND E1=E2); X1:=ref(barslast(H1),1)+1; F1:=backset(H1 AND count(L1,X1)>0,llvbars (if(L1,l,10000),X1)); G1:=F1>ref(F1,1); I1:=backset(G1,2); LD:=I1>ref(I1,1);{过滤后低点} L2:=LD OR barstatus=2 OR barscount(c)=1; X2:=ref(barslast(L2),1)+1; F2:=backset(L2 AND count(H2,X2)>0,hhvbars (if(H2,h,0),X2)); G2:=F2>ref(F2,1); I2:=backset(G2,2); HD:=I2>ref(I2,1);{过滤后高点} R1:=backset(barstatus=2,barslast(HD)+1); S1:=R1>ref(R1,1); {前一高} T1:=backset(barstatus=2,barslast(LD)+1); U1:=T1>ref(T1,1); {前一低} R2:=backset(S1,ref(barslast(HD),1)+2); S2:=R2>ref(R2,1); {前二高} T2:=backset(U1,ref(barslast(LD),1)+2); U2:=T2>ref(T2,1); {前二低} 短期压力:drawline(S2,h,S1,h,1),Colorred; 短期支撑:drawline(U2,l,U1,l,1),Colorgreen;

解答：

?{参数 N(5,1,100);}

A1:=REF(H,N)=HHV(H,2*N+1);
