GoCryptoTrader unifies trades and order update events by composing an order.Detail object. This is the full list of order.Detail fields that exchange implementations should populate on streamed trade/order-update events. As exchanges provide different APIs, not all fields are mandatory.
Note to developers: a special mention is the AverageExecutedPrice, which is not always provided, but its presence is important and highly desirable. Even if not reported, effort should be made to compute it out of reported trades.
