Modifying "order management" section of an existing EA

Currently, this EA:

 Opens order when certain condition is met.

 A fixed SL/TP is set from the beginning. 

 A unique magic number is given for each pair/timeframe

I need this EA to do additionally:

 When an order is opened, open another order in the same direction(like duplicating) 

 The duplicated order must NOT have a fixed SL/TP

 A new set of magic number must be given to each pair/timeframe, different from the original order's magic number(important! Unique magic number for each pair and its timeframe)

There must be newly added parameter options for these changes.

 For example: Duplication on/off, what magic numbers of orders(one for each timeframe) to be generated.

Thanks for your interest!
