TrendLine question

[csipi]

Hello guys,
I'm new in ForexTester programming.
I created lots of expert advisors in mql4, but now i must to translate one to ForexTester.
Can somebody help me, how can i get the value of a trend line at the current bar?
I can get the trendline properties(name, price1, etc.), but i can't find any function like getValueByShift in mql4.
I tried to shift the trend line times to the past and ask it length with the iBarShift function, but sometimes, it returns -1 (first i get the correct value, then during the next bar -1, then the correct value again. It is randomly).
Could somebody help me?

Thank you

Please try this function. It should do what you need.

Code: Select all

function GetTrendLineValue (TrendLineName: string) : double;
var y, x1,x2,x, y1, y2: double;
begin
    if ObjectExists(TrendLineName) then  begin  y1 := ObjectGet(TrendLineName, OBJPROP_PRICE1);
                                              y2 := ObjectGet(TrendLineName, OBJPROP_PRICE2);
                                              x1 := ObjectGet(TrendLineName, OBJPROP_TIME1);
                                              x2 := ObjectGet(TrendLineName, OBJPROP_TIME2);
                                              x:=iTime('GBPCHF', 1, 0);
                                              y:=(x-x1)*(y2-y1)/(x2-x1)+y1;
                                              result:=y;
                                          end
                                         else result:=-1;


end;

Hello,
I tried this before, but it doesn't work well when the trendline goes through one or more weekend period.

Thank you for your answer, other idea?

Sorry but trendlines in Forex Tester are not designed to work with "one point in future" especially if you draw them through weekend. Please try using the ray with 2 points in known data, this should work.
