Complete Program with the extras

[mlbalch]

I am very new to Ninja Script and C#. I have a strategy and have found much help in the forum, however there are a few things I do not understand.
What are all the nec parts to make the program work? I have seen #Region, namespace, class, protected override, etc...
Could someone write a very simple complete program so I can see everything from start to finish?
Maybe: buy at the mrkt open with a limit order, 3pt target and 2.5 pt Stop.

In each and every NinjaTrader installation, there is a sample strategy called "SampleMACrossover". This is a complete strategy and this is the code:

Thanks so much Austin. I will study this and put the pieces together and hopefully not have too many errors.
