Modify an exixting expert advisor

Looking to modify an expert advisor.

I need to modify the hedging part of this ea. I want it to be able to close the first position and then open a new one that will attemp to recover the loss of the first one with a profit of 30 pips.

The EA will continue to close positions and open new ones until the desired take profit.

Right the ea keeps all positions open until the desired take profit is reached.

I want the ea to keep track of lossse s even thought the position has been closed.

I alos want a built spread protection in case the market increases the spread to much.

Also is possible to hide stop orders of new positions? So they are internal and the broker cant see them.

Let me know if you are interested.

Thanks

David
