通达信突破N天预警指标公式

N:=5;
上趋势:=MA(LOW,20)*1.2,COLOR0080FF,LINETHICK2;
次上趋势:=MA(LOW,20)*1.1,COLORYELLOW;
次下趋势:=MA(HIGH,20)*0.9,COLORWHITE;
下趋势:=MA(HIGH,20)*0.8,COLORGREEN,LINETHICK2;
ZD:=(C-REF(C,1))/REF(C,1)*100;
HDZF:=(HHV(H,20)-C)/(HHV(H,20)-LLV(L,20));
趋势强度:=IF(C>次上趋势,IF(C>上趋势,4,3),IF(C>次下趋势 AND C<次上趋势,2,IF(C<下趋势,0,1)));
N天强势:趋势强度>2 AND REF(趋势强度>2,N-1);
