Hello,

Welcome to the forum, I think it is not difficult to find an EA crossover, it has been done many many times.
If you look through the post you will find example of EA crossover (including if you look at my post).
Then if you use metatrader it is really simple, just replace the value of the moving average by yours (fast MA and slow MA), put the good time frime and and the MA type and you will be done.

Cheers,
S.
