Mình có thêm một chỉ báo mới cho các bạn nè. Cái đây còn ghê hơn nữa, lướt sóng cực chuẩn lun

Công thức Metastock:

sx:=Input("date of first point [ mmddyyyy ]",1,12350000,1032000);
sxt:=Input("intraday time of first point[ 24 hour - hhmm ]",0,2460,0);
ex:=Input("date of second point [ mmddyyyy ]",1,12350000,1032001);
ext:=Input("intraday time of second point[ 24 hour - hhmm ]",0,2460,0);
prs:=Input("scaling factor for slope calculation",1,100000,1);
ops:=Input("shift value for affine display",0,100000,0);
sdt:= (Month()=Int(sx/1000000)) AND
(DayOfMonth()=Rnd(Frac(Int(sx/10000)/100)*100)) AND
(Year()=Rnd(Frac(sx/10000)*10000)) AND
(Hour()= Int(sxt/100)) AND
(Minute()=Rnd(Frac(sxt/100)*100));
edt:=Month()=Int(ex/1000000) AND
DayOfMonth()=Rnd(Frac(Int(ex/10000)/100)*100) AND
Year()=Rnd(Frac(ex/10000)*10000) AND
(Hour()= Int(ext/100)) AND
(Minute()=Rnd(Frac(ext/100)*100));
rise:=LastValue((ValueWhen(1,edt,C)-ValueWhen(1,sdt,C))*prs);
run:=LastValue(ValueWhen(1,edt,Cum(1))-ValueWhen(1,sdt,Cum(1)));
sl:=rise/run;
tr:=((C-LastValue(ValueWhen(1,sdt,C)))-(Cum(1)-LastValue(ValueWhen(1,sdt
,Cum(1))))*sl);
tr+ops
