i am going to backtest kind of yearly price levels and in order to becktest it i need to plot lines not in Ray format and becouse of number of lines i can't use buffer format
my question is : can we define start and end of a year included past and current years as timedate variables in mt4
do you have any other solutions
like this that i use for monthly periods :
Inserted Code
Mtime1=iTime(NULL,Mperiod,Mshift);  // 
      if (Month()==1 || Month()==3 ||Month()==5 ||Month()==7 || Month()==8 || Month()==10 || Month()==12) Mtime2=Mtime1+(PERIOD_MN1+PERIOD_D1)*60;
      if (Month()==2)  Mtime2=Mtime1+(PERIOD_MN1-PERIOD_D1)*60;
      if (Month()==4 || Month()==6 || Month()==9 || Month()==11) Mtime2=Mtime1+PERIOD_MN1*60;

I haven't actually done it, but have done similar things.

Just find the datetime value for Jan 1st of the following year and subtract 1 (second) from the answer to give you the end of the previous year. Or find the start of day of Dec 31 and add 24*60*60-1 to the answer.

The way you are proposing to do it would cause problems because of leap years. Just reuse the same calculation for every year, should not be too hard.
