Copy EA trade and close trades

i have an expert advisor (lets call it EA1). it opens buy and sell orders.

I would like a custom EA (lets call it EA2) which will monitor the trades opened by the other EA1.

And when a trade is opened by EA1 and the price is moving against the position, the EA2 should copy the trade with a bigger lotsize in the opposite direction opened by EA1.

And close both buy and sell trades when they break even or its in min profit.

Eg.

EA1 opens a sell position.

price moves up.

EA1 opens a buy position. 

EA2 should open a buy position with x lotsize (bigger than the buy position opened by EA1)

When floating loss is >= 0, close all positions.
