Represents a collection of CQGTrade objects.

There are two instances of CQGTrades collection used in CQG API CQGPosition objects: one for open trades, one for matched trades.
Access to an item in this collection can be made by its index. The index is 0 based, i.e. the index of the first item in the collection is 0.
See Accessing non-existent collection items for details on accessing items that do not exist in the collection.
See the usage of CQGTrades collections in the AccountChanged event's example section.
