Looking for an Entry Order EA / Script

Hi,

I'm am looking for an expert advisor or script (I really don't understand very well which one would be more appropriate), that allows me to place an entry order (buy or sell) based on price reaching a defined moving average level - ie. one that automatically keeps adjusting the entry level until the moving average is reached and entry order is triggered. The objective would to help automate my order entry, so that I don't have to be continuously staring at the charts until the condition is met.

Does anybody know of anything in the mql4 code base that does this, or someone that can help program this for me?

I have attached the logic I would like to implement, for those who are interested.

I think you could build this for free using the EA wizzared in MT5. Lots fo MT5 filesfor free that use a simliar approach.
