MQL4 problem with code

[Masimus]

I have problem with mql4 code.

When I start code in  tester of strategy, program sometimes lost data.

The program should print the information every 30 minutes.

It starts at 00:00 and then prints 01:00 (lost 0:30) or prints only part of the data.

Typically, the error is at the beginning of the data.

I do not know why it appears that this situation.

Can you help?

The code is simple.
