   char   data[];
   char result_data[];
   string url = "https://www.forexfactory.com/calendar.php?day=dec27.2018";

please help me.

 

How did you test this?
I think mostly you received this error on TESTER.

As i know in MQL5 you couldn't get respond of web request from tester. but i works on live trading (demo or live account doesn't matter)

I don't know why its not working and what is the logic behind it.
