I'm tired of these infinite errors. What's wrong here?

Welcome.

 Just reading the book and decided to practice. I copied the code from here. So is it not true?

Your code differes from the one in the book, at least related to the first post.

Checking the result of your "OrderSelect" statement should be done. - This way you continue to check all orders by position, even if a call fails. 

Also, you should change the for-loop as follows, as the amount of open orders could shrink while processing.

   for(int cnt = OrdersTotal() - 1; (cnt >= 0) && !_StopFlag; cnt--)
   {
     if(!OrderSelect(cnt, SELECT_BY_POS))
     { continue; }                // EA HASN'T BEEN MADE YET. JUST SENDING YOU THE PART OF THE CODE WHICH HAS 11 ERRORS.
     RefreshRates();
   }
