| MT5 · Trade return codes | 10040 TRADE_RETCODE_LIMIT_POSITIONS | The number of open positions simultaneously present on an account can be limited by the server settings. After a limit is reached, the server returns the TRADE_RETCODE_LIMIT_POSITIONS error when attempting to place an order. The limitation operates differently depending on the position accounting type: Netting — number of open positions is considered. When a limit is reached, the platform does not let placing new orders whose execution may increase the number of open positions. In fact, the platform allows placing orders only for the symbols that already have open positions. The current pending orders are not considered since their execution may lead to changes in the current positions but it cannot increase their number. Hedging — pending orders are considered together with open positions, since a pending order activation always leads to opening a new position. When a limit is reached, the platform does not allow placing both new market orders for opening positions and pending orders. | YI GOLD suggestionsCheck permissions, sessions, symbol specifications, quotes and request parameters.
