Date time of Previous Year

New comment
 

Hi there,
I tried and tried to get the open date of the previous year.
Can you help me please ?

Now, i do it like this but, it's not "pro"

datetime  PREV_YEAR_OPEN_DATE=D'2017.01.001 0:00';
   
datetime PREV_MONTH_OPEN_DATE=iTime(Symbol(),PERIOD_MN1,1);

datetime PREV_WEEK_OPEN_DATE=iTime(Symbol(),PERIOD_W1,1);

datetime PREV_DAY_OPEN_DATE=iTime(Symbol(),PERIOD_D1,1);

Regards.

 
  1. Please use the SRC-button if you post code (more than one line)
  2. Have you checked the error messages?
  3. What did you get and what did you expect: PREV_YEAR_OPEN_DATE ?
  4. Maybe you shouldn't use: "2017.01.001 0:00" but try:
  5. datetime  PREV_YEAR_OPEN_DATE=D'2017.01.01 00:00';

Hello,
I do not get any error.
But i need it to be like the previous month (for example).

datetime PREV_MONTH_OPEN_DATE=iTime(Symbol(),PERIOD_MN1,1);

I find how to get the high and low price of the previous year

PREV_YEAR_HIGH = iHigh(NULL, PERIOD_MN1, iHighest(NULL, PERIOD_MN1, MODE_HIGH, 12, Month()));

And i need the open time now.

Thank you very much.

  1. You already know how. You posted the code. Since MT doesn't have yearly charts you have to find the MN1 indexes yourself.
    #define INDEX uint
#define PRICE double
datetime startOfMonth    = iTime(Symbol(),PERIOD_MN1,0);
INDEX    iMnLastYearLast = TimeMonth(startOfMonth);       // MN1 last bar of last year.
INDEX    iMnHighestMonth = iHighest(NULL, PERIOD_MN1, MODE_HIGH, 12, iMnLastYearLast);
PRICE    HHlastYeat      = iHigh(NULL, PERIOD_MN1, iMnHighestMonth)

  2. On MT4: Unless the current chart is the specific pair/TF referenced, you must handle 4066/4073 errors.

  3. "Open time" of what "now?" The year? iMNCurrYearFirst = iMNLastYearLast + 1

Thank you for your response.

   MqlDateTime time;
   TimeCurrent(time);
   time.year--;
   time.mon=1;
   time.day=1;
   time.min=0;
   time.sec=0;
   time.hour=0;
   
   Print("Last year's start time = ",StructToTime(time));

If iMnLastYearLast is December of last year, isn't January iMnLastYearLast+11? When in doubt, think.
 

Nothing work to me...as my coding skills are limited.
I will put the date manually.

Anyway, thank to all 3 of you very much for your time.
Regards.

As I continue to learn, i finally got it from your code.
Thank you very much.
