Create an Entry Limit Order

A regular entry order opens a position when the specified market condition is met.

A netting entry order closes all positions for the specified instrument and account which are in the direction (buy or sell) opposite to the direction of the entry order.

A limit entry order with a sell direction is filled when the market is above the rate specified in the order.

A limit entry order with a buy direction is filled when the market is below the rate specified in the order.

Please note that if hedging is disabled for the account, the order, first, closes existing opposite positions for the same account and instrument and only then opens a new position in the remaining amount.

Note: If-Then Orders. If the order is a sell limit entry order with the order amount equal to zero. This order can be created above the market, and will be triggered when the market crosses the order rate up. Such order does not create or close any trades. If the order is used as a root order of the OTO, such order will activate all other orders included into the OTO group, so, you can use it for conditional activation of other orders.

Valuemap field	Datatype	Description
Command	string	The command. Must be `CreateOrder`.
OrderType	string	The type of the order. Must be `LE`.
OfferID	string	The identifier of the instrument the order should be placed for. The value must be obtained from the "Offers" table, the `OfferID` column.
AcctID	string	The identifier of the account the order should be placed for. The value must be obtained from the "Accounts" table, the `AccountID` column. Please note that the account identifier may not necessarily be equal to the account name which is shown in the Trading Station application.
BuySell	string	The order direction. The value must be `B` - for buy orders and `S` - for sell orders.
Quantity	number	The quantity of the instrument to be bought or sold. The quantity is expressed in contracts and must be divisible by the value of the lot size (see `baseUnitSize` trading option in the following call: `core.host:execute("getTradingProperty", ...)`). The quantity must not be specified in case the value of the `NetQtyFlag` field is `y`.
NetQtyFlag	string	The net quantity flag. The value can be either `y` or `n`. The value is optional. The default value is `n`. An entry order in the netting mode does not create any positions but closes all positions which exist at the moment of the order filling and which are created for the order account and order instrument in the direction (see `BuySell`) opposite to the direction of the order.
Rate	number	The rate at which the order must be filled. The sell order rate must be above the market. The buy order rate must be below the market.
TrailUpdatePips	number	The trailing entry order follows the market in case the market moves in the direction opposite to that of the order (i.e. when the distance between the order and the current market price increases). The value specifies the maximum change of the market price after that the rate of the order will be changed as well. The value is expressed in pips. If the value is 1, it means that the dynamic trailing mode is used, i.e. the order rate is changed with every change of the market price. Please note that in some systems, only dynamic trailing mode is supported. See `core.host:execute("getTradingProperty", ...)` for details about permitted types of the trailing mode. In case only dynamic trailing stop is supported, any non-zero value of this parameter will cause creating a dynamic trailing stop. The value is optional. By default, this value is 0. 0 means no-trailing order.
GTC	string	Time-In-Force value. Can be GTC (Good-Till-Cancelled) or DAY (Good-Till-End-Of-Day). The value is optional. Conditional orders are GTC orders by default.
CustomID	string	The custom identifier of the order. This value will be populated into all order-related QTXT columns of the following tables: "Orders", "Trades", and "Closed Trades".
ContingencyID	string	Specify the identifier of the existing contingency group to include the order into the that group. Don't specify the parameter if the order must not be included into any contingency group.
