Looking for EMA-based entry EA

I am trying to find a EA/Script that will follow a selected EMA to enter a order, so lets say a 50 ema i put the ea on the chart and the order follows the 50 ema as it moves up or down until price hits it. Doesnt have to be anything fancy as I would manage the trade after its in.
Appreciate any help.
Cheers

I believe EA builders have this feature.

Cheers CM where would I find them, I did a search but as you can imagien the crap that came up when put that in.

I haven't looked at these for several years now so I don't remember names.

MT5 has an EA builder.
