Hull MA EA modification for better entries.

I am looking for someone to modify Alexander Fedorov's Hull Moving Average EA which I have purchased for $118. It uses two, user specified, Hull MA's and executes a Buy order when both MA's are going up and Vice Versa for Sell orders. However this means that orders are triggered any time these two parameters are met which, naturally, could be at less than optimal times. I need it to execute Buy orders only when the Fast Hull MA changes direction and the new direction is following the same trend as the Slow Hull MA ie. when the curve changes from down to up for Buy orders and the reverse for Sell orders. It would be useful to have a 3rd 200 Hull MA (for example) as a filter also. 

In Alexander's version, he say's it is designed to operate on the EUR/USD but I would like to apply it to any Currency pair or even Indices if possible. I need it to work on 30 minute TF and above.

Many thanks

Mark
