Operativity

I am trading with a demo account from Metaquotes Demo.
When I do an operation (buy or sell) and in the meanwhile the price goes opposite my direction i get the price I request even if at the moment the price is better for me. The same happens when i close an order. Is this the correct behaviour also with real money account?
I don't know if i was clear enough. Excuse my english
Thanks in advance for your answers.
