Modify an existing EA with 2 additions..... a hedge function and close 2 random counter trades

Hi all,

I have a DCA XAUUSD bot, now I want to add a hedge function to my bot.

Requires: 1 - Opens hedge entry when DCA entry reach to xx entry ( for example: DCA entry = 10, stop open DCA entry and open Hedge entry with logic same as DCA logic already had in my code) with Hedge entry volume = 2 * 1st dca volume.

               2 - When DCA + HEDGE entry ( total open entry)  reach to xx entry ( for example: total entry = 20).  Close random 2 counter entries( 1 dca + 1 hedge) that has  xx pips profit (  for example: 05 pips profit).  Close all open orders when total profit reachs xx Pips (   for example: 10 pips profit in total) or close all  open orders at 1st DCA entry.
