Add pending orders to an existing EA.

I want to add Buy stop / sell stop to my EA.

- The pending orders should expire in minutes entered. Lets say i want the orders to expire in 50 minutes after open.

- The Pending orders should be opened at certain distance from current price. lets say i want them to open 10 pips away from current price.

-I should be able to choose between market orders and pending orders. Market orders already in place.

   enum enumtradedirection   {   buy=0,   // Buy Only

                                                 sell=1,  // Sell Only   

                                                 both=2,  // Buy & Sell 

                                                 Buy Stop=3 ,  //Buy Stop Only

                                                 Sell Stop=4,   //Sell STop Only

                                                 Both Pending= 5   // Buy & Sell Stop

                                              }; 

- The Pending orders should work with the already functionality of the EA
