Moving Avarage Cross Over

I am looking to further develop a simple EA I already made that is based on MA crossover.

The problem with the one I have, it uses TP and SL to close a trade.

I would for the order to close when the next cross over happens, the old order will close and the new one will open.

Below is what I have so far:
