quando compilo mi escono questi errori

Please:

1. Use the code button from the header (</> or Alt+S) if you post code!
2. Edit your post according to #1
3. Describe the error with the log entry and the line it refers to.

Mario Soattini: can someone help me thanks.

1. Use the code button.

2.    datetime from_time = StrToTime("1970.01.01 00:00");

   Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?
             General rules and best pratices of the Forum. - General - MQL5 programming forum? (2017)
   Next time, post in the correct place. The moderators will likely move this thread there soon.

3. Please post only in English on this part of the forums. Use the automatic translation tool if needed. Use simple language structure when using mechanical translation. (2013)
   Or use the Italiano forum

4. This may not work, extra spaces in the string.	datetime from_time = StrToTime(" 1970.01 . 01 00 : 00 ");
   This is the same as	datetime from_time = StrToTime("1970.01.01 00:00");
   this	datetime from_time = D'1970.01.01 00:00';
   and this	datetime from_time = 0;

   
   

5. Help you with what? You know what the problem is; undefined functions. Show us your attempt (using the CODE button) and state the nature of your difficulty.
