abdI do you want to set a fixed datetime point like 24.11.2010 00:00 and set BarsAHead. Indicator shall draw 1 vertical line from 24.11.2010 00:00 + BarsAhead or till last bar many?
 

hi ..thanks for u my frind......this what i need

indicator shall draw 1 vertical line from 24.11.2010 00:00 + BarsAhead

' but the startdate and barsahead is avariables that i could change from the indicator settings

  
ObjectCreate(LineName, OBJ_VLINE, 0,StartTime + (BarsAhead * Period()*60), High[0] );

ho BTW 

ObjectDelete(LineName);

& not 

ObjectDelete("OBJ_VLINE");
 

hi

thanks for u qjol for ur help

after using ur code......i enter 20 in the BarsAhead setting  but the indicator draw the line after 14 bar......may be because the indicator count the holidays.......... 

 

what's value u used for starttime & what TF u using to check

 

the time frame is daily.......the value for starttime is as in the original code post #1

by the way i removed this part of the code 

   int D=StartTime;
int i=BarsAhead;i=i*10;

because i think it's not useful 

 

because there is 3 weekends between StartTime & StartTime + (BarsAhead * Period()*60) = missing 6 days

 

hi qjol

i want the indicator to ignore weekend..and count bars only....if i give the indicator a starttime.and 15 in barsahead

the indicator will draw the Vline after 15 bars ignoring the weekend

could that be done in mql4?

u have to find how many weekends u have & add it to BarsAhead * Period()*60
