如何在 mql5 中获取明天的日期？

Question

I want to draw a horizontal trendline that extends from today to tomorrow, And I have trouble getting time tomorrow.

for example today is 2021.12.17 00:00:00

Comment( iTime(_Symbol, PERIOD_D1, 0) + (PERIOD_D1*60) );

// Today: 2021.12.17 00:00:00    
// MQL4:  2021.12.18 00:00:00 ... it's ok.
// MQL5:  2021.12.28 09:28:00 ... it's not ok! why?

MQL4 : As you can see in the code above, in mql4, through the iTime function and adding a period, the date of tomorrow can be obtained, it's return 2021.12.18 00:00:00 .

MQL5 : But this code shows date 2021.12.28 09:28:00 in mql5.

In other words, PERIOD_D1 is equal to 1440 in mql4 but in mql5 is equal to 16408 , Why?

Comment(PERIOD_D1);
// MQL4: 1440
// MQL5: 16408 why?!!!

Answer 1

Try this: SELECT DATE_ADD('2018-05-01',INTERVAL 1 DAY); The function was introduced in MySQL 4.0. Some details are available here: https://www.w3schools.com/sql/func_mysql_date_add.asp .

You can also use now() + interval 1 day or curdate() + interval 1 day an answer was available at stackowerflow here: https://stackoverflow.com/a/3887517/5043424

Answer 2

Unlike MQL4, PERIOD_D1 does not relate to the amount of minutes in the period in MQL5. The simple workaround is to add (1440*60) to iTime().

Alternatively, use PeriodSeconds() as below

iTime(_Symbol, PERIOD_D1, 0) + PeriodSeconds(PERIOD_D1)
