Modification of Mt5 EA

I have a functioning EA that Trades based on specific logic. I want the following modifications. The primary purpose of this modification is to be able to use it in mt5 optimization smoothly (without errors). 

1) EA must not trade the Pair that it is running instead in the EA properties a dropdown variable with 28 pairs must be added. EA will trade the pair that is selected from this dropdown menu. 

2) Please add Recovery Trade: True/False

If this property is turned true, (if false, EA must trade exactly as it's trading now) 

a) EA will not set SL and instead open a new trade in the same direction of the initial trade when price moves against our first trade (use SL variable as grid level). EA will continue to open more trades if prices goes against us. 

b) Recovery_Basket_Target: $$$    ( When price finally comes in our favor, EA will basket all trades together and close them all at $$$ profit) - please add this variable.
