TRADE_RETCODE_CLOSE_ORDER_EXIST

A close order already exists for a specified position. This may happen when working in the hedging system:

  • when attempting to close a position with an opposite one, while close orders for the position already exist
  • when attempting to fully or partially close a position if the total volume of the already present close orders and the newly placed one exceeds the current position volume

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.

10041

TRADE_RETCODE_REJECT_CANCEL

The pending order activation request is rejected, the order is canceled

10042

TRADE_RETCODE_LONG_ONLY

The request is rejected, because the "Only long positions are allowed" rule is set for the symbol (POSITION_TYPE_BUY)

10043

TRADE_RETCODE_SHORT_ONLY

The request is rejected, because the "Only short positions are allowed" rule is set for the symbol (POSITION_TYPE_SELL)

10044

TRADE_RETCODE_CLOSE_ONLY

The request is rejected, because the "Only position closing is allowed" rule is set for the symbol

10045

TRADE_RETCODE_FIFO_CLOSE

The request is rejected, because "Position closing is allowed only by FIFO rule" flag is set for the trading account (ACCOUNT_FIFO_CLOSE=true)

10046

TRADE_RETCODE_HEDGE_PROHIBITED

The request is rejected, because the "Opposite positions on a single symbol are disabled" rule is set for the trading account. For example, if the account has a Buy position, then a user cannot open a Sell position or place a pending sell order. The rule is only applied to accounts with hedging accounting system (ACCOUNT_MARGIN_MODE=ACCOUNT_MARGIN_MODE_RETAIL_HEDGING).
