Returns the number of current orders.
Value of the int type.
Do not confuse current pending orders with positions, which are also displayed on the "Trade" tab of the "Toolbox" of the client terminal. An order is a request to conduct a transaction, while a position is a result of one or more deals.
For the "netting" interpretation of positions (ACCOUNT_MARGIN_MODE_RETAIL_NETTING and ACCOUNT_MARGIN_MODE_EXCHANGE), only one position can exist for a symbol at any moment of time. This position is a result of one or more deals. Do not confuse positions with valid pending orders, which are also displayed on the Trading tab of the Toolbox window.
If individual positions are allowed (ACCOUNT_MARGIN_MODE_RETAIL_HEDGING), multiple positions can be open for one symbol.
