oandapyV20.contrib.requests module contains several classes
that can be used optionally when creating Order Requests.
When creating an order to create a position, it is possible to create dependant orders that will be triggered when the position gets filled. This goes typically for Take Profit and Stop Loss.
These order specifications and additional data that goes with these order specifications can be created by the contrib.requests.*Order* classes and the contrib.requests.*Details classes.
