In the Global Settings, you can configure the copier status. It will define whether the copy of trading is currently active or not. You can choose to copy all trades, or copy only trades that open (Open Only) or close a position (Close Only), or to deactivate the copy (Trade Copier is...). In such cases, you could receive a "Deleted: Trade Copier is OFF/OpenOnly/CloseOnly Mode" order status if your master tries to place an order.
