Please help with very simple strategy (bollinger) to beginner

[memonolog]

Hi, need help with very simple strategy on bolinger bands

Ned to:
When bar open is higher than the Bollinger upper line, and the close of the bar is lower than Bollinger upper line - go Short.
And
When bar open is lower than the Bollinger Lower line, and the close of the bar is upper than Bollinger Lower line - go Long.

Please help to understand the code for complete beginner.
Very thanks for the help!

My wrong code:

	IsInstantiatedOnEachOptimizationIteration	= true;
			}
			else if (State == State.Configure)
			{
			}
			else if (State == State.DataLoaded)
			{				
				Bollinger1				= Bollinger(Close, 2, 14);
			}
		}

		protected override void OnBarUpdate()
		{
			if (CurrentBars[0] < 1)
			return;

			 // Set 1
			if ((CrossAbove(Bollinger1.Upper, Open, 1))
				 && (CrossBelow(Bollinger1.Upper, Close, 1)))
			{
				EnterShortLimit(Convert.ToInt32(DefaultQuantity), 1, @"GoShort");
			}
			
			 // Set 2
			if ((CrossAbove(Bollinger1.Lower, Open, 1))
				 && (CrossBelow(Bollinger1.Lower, Close, 1)))
			{
				EnterLongLimit(Convert.ToInt32(DefaultQuantity), 1, @"GoLong");
			}
			
		}
	}
}
