  1. Weekly/Monthly is not supported in the tester.
              'Testing Features and Limits in MetaTrader 4' - MQL4 Articles 2012 (The comment about “Zero bar of another timeframe,” is no longer valid.)

  2. On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

This is one of the reasons why, in my opinion, you should only use trend-lines on the TF where they are drawn.

Although the 2 time anchors are different on the H4 chart, on the weekly chart both of them are within the same bar. This means that the trendline is vertical and that is why you are getting 0.

Try a start and end  point that are in different weeks and you will get values.

Yes the start and end point work fine...but i have problem when i try to get the price of other shifts of the trendline...

Is there any other way that could make it work...i have to create an MTF Trendline indicator and get prices from all shifts of the trendline

Did you read my post that you have quoted?

If the trend-line is vertical there are no other shifts to get values from.

There is error : the name of the line is not the same

  if(ObjectFind(NULL,label)==0)
       ObjectDelete(label);

   
   ObjectCreate(label, OBJ_TREND, 0, iTime(NULL,Timef 

ObjectGetValueByTime(NULL,label,iTime(NU

And also you have to add a  fonction :  int start()

 ObjectGetTimeByShift require an id_chart

in the others fonctions it is facultative, we can put an chart_id or not.

OjectCreate have to have a chart_id, so the name of the line is the same in the two fonctions 

double  ObjectGetValueByTime( 
   long       chart_id,      // chart ID 
   string     object_name,   // object name 
   datetime   time,          // time 
   int        line_id=0      // line ID 
   );
bool  ObjectCreate( 
   long          chart_id,      // chart ID 
   string        object_name,   // object name 
   ENUM_OBJECT   object_type,   // object type 
   int           sub_window,    // window index 
   datetime      time1,         // time of the first anchor point 
   double        price1,        // price of the first anchor point 
   ... 
   datetime      timeN=0,       // time of the N-th anchor point 
   double        priceN=0       // price of the N-th anchor point 
   );
 

The function creates an object with the specified name, type, and the initial coordinates in the specified chart subwindow:



bool  ObjectCreate( 
   string        object_name,   // object name 
   ENUM_OBJECT   object_type,   // object type 
   int           sub_window,    // window index 
   datetime      time1,         // time of the first anchor point 
   double        price1,        // price of the first anchor point 
   datetime      time2=0,       // time of the second anchor point 
   double        price2=0,      // price of the second anchor point 
   datetime      time3=0,       // time of the third anchor point 
   double        price3=0       // price of the third anchor point 
   );
