Adding extra Update in my mql4 ea

I want to add two options in my ea it already have martingale but i need extra martingale option so to decide if to use it main martingale strategy or to use the new martingale option you will put in the new martingale option I can choose what lot size it will start with. 

Last update is base on auto close 

Example the ea know when to buy or when to sell now what I want is option of if it have a signal of buy and opened position if the position have not closed then in the same pair the ea confirm sell signal if the buy is still open let the ea automatically close the buy position and wait for any entry from the sell. Also put graphic so it shows how much loss or profit in the chart screen. If you can deliver fast in a day I have other 5 EA to create
