backtesting help

Hi I have a question.

why if in my bot I put the function System.Threading.Thread.Sleep (); does backtesting wait for real and non-virtual time?

or why if I put a similar logic

while ((Mv.Result.LastValue - Mv.Result.Last(30)) < Symbol.PipSize * 60)
                                {
                                    Print("waiting for triger");
                                }
                                ExecuteOrder(position.Quantity * 2, TradeType.Buy);

the backtesting dosn't work?

should i change settings?

thanks
