IB::Alert#AddOrderstateAlert

The OrderState-Record is used to record the history of the order. If selected Alert-Messages appear, they are added to the Order.order_state-Array. The last Status is available as Order.order_state, all states are accessible by Order.order_states

The TWS-Message-text is stored to the »warning-text«-field. The Status is always »rejected«. If the first OrderState-object of a Order is »rejected«, the order is not placed at all. Otherwise only the last action is not applied and the order is unchanged.
