{STICKLINE(C>0,37,50,4,0),COLOR003800;
37,COLORGRAY;
50,COLORGRAY;}
AA:=SMA(MAX(C-REF(C,1),0),8,1)/SMA(ABS(C-REF(C,1)),8,1)*100,COLORFFB5FF;
BB:=90-AA,COLORFFFF7F;
X0:=((C-LLV(L,33))/(HHV(H,33)-LLV(L,33)))*67;
X1:=MA(3*SMA(X0,33,1)-2*SMA(SMA(X0,43,1),5,1),2);
X2:=IF(X1>REF(X1,1),X1,X1+2*(X1-REF(X1,1)));
趋势:=(EMA(X2,7))+20,COLOR0068FF;
X_L1:=(O+C*3+L+H)/6;
X_L2:=V*X_L1;
X_L3:=REF(SUM(X_L2,5)/SUM(V,5),1);

A1:=COUNT(BARSLAST(趋势<REF(趋势,1)),BARSLAST(趋势<REF(趋势,1)));
A2:=CROSS(AA,BB);
A3:=CROSS(AA,50);
A4:=A2 OR A3;
A1 AND A4 AND C>=X_L3;
