Simple martingale ea

i need martingale ea which can post 20 pending orders at start , it will post 10 orders above and 10 orders below the current price , i should be able to set manual lot size for all 20 orders , the distance between each order will be defined in pips (editable) as order step .i should be also able to select if first order is a buy or sell or just pending orders from current market to given distance. , ea will use $ TP to close single or multiple orders . when any order closed in profit ea will have the option to auto start again or stop working till started again .
