Metastock System ...

Good friends, i would like ask, if you help me to design a simple Metastock system or metastock expert, with the following condictions:

Buy signal: when i put a uptrendline in the chart and the prices close below of this uptrenline and this bar is blanc (close above open).

Sell signal: when i put a downtrendline in the chart and the prices close above of this downtrenline(close below open).

Best regards

Sorry but the conditions are wrong. The new condictions are obvious:

Buy signal: when i put a downtrendline in the chart and the prices close above of this downtrenline and this bar is blanc (close above open).

Sell signal: when i put a uptrendline in the chart and the prices close below of this uptrenline and this bar is black (close below open).

Best regards

Dear Goin

As far as I understand Metastock does not have a function to recognize the user drawn trend line unlike Amibroker in which line studies made by the user can be named and used in scans and explorations.

Friend Karthik,

I discover in internet one formule to draw one trendline in a graph. Is necessary only select date periods.
Do not permit extensions on the right/left.
With this formule modified is not possible create the system.
Perheps it is necessary introduce the right/left extensions and creat a funtion that recognize this trendline.
The formule of trenline is:

{ Trendline - date range v3.0}

{ Dates user input }
StDay:=Input("start Day",1,31,1);
StMnth:=Input("start Month",1,12,1);
StYear:=Input("start Year",1800,2200,2006);
EnDay:=Input("end Day",1,31,1);
EnMnth:=Input("end Month",1,12,6);
EnYear:=Input("end Year",1800,2200,2006);

{ Selected date periods }
start:=Year()>StYear
OR (Year()=StYear AND (Month()>StMnth
OR Month()=StMnth AND DayOfMonth()>=StDay));
end:=Year()<EnYear
OR (Year()=EnYear AND (Month()<EnMnth
OR Month()=EnMnth AND DayOfMonth()<=EnDay));

{ Date signals }
date1:=start AND Alert(start=0,2);
date2:=end=0 AND Alert(end,2);
date2:=Zig(end AND Cum(1)>1,1,$)=1;

{ Restrict out of range dates to chart }
date1:=If(LastValue(Cum(date1))>0,date1,
Cum(1)=1);
date2:=If(LastValue(Cum(date2))>0,date2,
LastValue(Cum(1))=Cum(1));

{ Sort dates in chronological order }
dateOk:=LastValue(BarsSince(date1))
>LastValue(BarsSince(date2));
day1:=If(dateOk,date1,date2);
day2:=If(dateOk,date2,date1);

{ Data Array type, levels }
dataArray:=L;
price1:=ValueWhen(1,day1,dataArray);
price2:=LastValue(ValueWhen(1,day2,dataArray));

{ Trendline definition }
x1:=LastValue(BarsSince(day1));
x2:=LastValue(BarsSince(day2));
trendline:=price1
+BarsSince(day1)*(price2-price1)
/Max(x1-x2,.000001);

{ Rem next line to extend plot to end of chart }
trendline:=Ref(Ref(trendline,-x2),x2);

{ Plot on price chart }
trendline
