MT4 EA/Script to automatically close positions based on size

Looking for an MT4 EA / Script to do the following;

when a trade is executed above a user definable size it will then close all open positions of that pair that are below a user definable size.

eg:

EA is set to close positions below 0.05 when a new position of over 0.06 is opened

there are 6 X open sell positions on USDJPY at 0.04

a new position is opened at 0.7 

the EA will close the 6 X positions that are 0.04

inputs:

max size of positions to be closed

min size of the position to trigger close

magic number of positions to be closed

magic number of trigger position to trigger close
