EA or Script for scaling out of trades...?

I am looking for an EA or script for metatrader MQL4 that will scale out of trades automatically.

I prefer to select my trades manually; however, it would be useful to automate trade management after I have entered the trade, so I can focus on finding trade opportunities.

Does anyone have one?

Or, can you make a suggestion as to where can find one?

Any help is appreciated.

Thanks

I'll be more specific.

I want to apply the script to specific entries I select. Ideally, the tool needs to be capable of reducing a position by percentage (ex: reduce a 10 lot by 6 to a 4 lot). The trigger should be individual to each open entry and pip (target) specific. It should work similar to the close order button on open trades.

I don't want it to generally close all open trades.

thanks again
