OptionalgetCreate an observable that will emit when the next reload of this list is complete. It will just emit (at max) one time and complete.
OptionalgetIf defined, clients can use this to get notified when a retry load makes sense. For example, data might not be ready at the broker initially.
In this case, loadNext might fail. However the data may become available later. If the broker implementation can observe this, it will notify
subscribers.
OptionalgetIf applicable for this list, this can be used to check if any warnings regarding the list (e.g. data that cannot be fully aggregated right now) should be shown.
If
getSummaryis defined, it returns a summary object of the OrderList. Currently this is only available for thepxtrades (viewhistory). The function should be called whenever rows are expected to have changed (i.e. when anModificationsObservableemits). Note that this API is subject to change if the feature turns out useful for other views. Clients may ignore this row if a total/summary row is not needed to be displayed.
