HistoryOrderSelect() clears in a mql5-program the list of orders from a history, available for calls, and copies to it a single order, if the execution of HistoryOrderSelect () has been completed successfully. If you need to go through all deals selected by HistorySelect(), you should better use HistoryOrderGetTicket().
