Questions from Beginners MQL4 MT4 MetaTrader 4 - page 233

 
Good day!
Can you please tell me where I can test my EA? The program or where to read the details of testing
In the tester MT4 for 2020 on D1 writes n/a, sometimes it gives 78%. The archive of quotations did not give any new data from M1 to D1.

Good afternoon. It's a simple question, but I have no one to ask, so I'm asking everyone. I'm starting my first steps in writing robots and I'm studying the codes of indices.

What does this 5203 error in WebRequest() mean and what can I do about it?
