Attach Stop and/or Limit Orders to the Command
Orders which create a new position (OM, O, OR, SE and LE orders) may also have additional values in the value map, which forces creating associated stop and limit orders.
Please note that close, stop and limit orders must be permitted for the account in order to be
used (see also core.host:execute("getTradingProperty", ...)
for details
about permissions).
Please note that stop and limit orders cannot be attached to the netting entry orders.
You can create either the regular stop and limit orders (for non-FIFO accounts) or ELS (entry limit-stop) orders for FIFO accounts. ELS is a pair of entry stop and entry limit orders which are joined into OCO (one-cancels-others) group, so when one of the order is executed, the other order is cancelled. Also, the orders only closes the existing opposite positions and never open the position. Also, the orders are cancelled when there is no opposite position is existing at the moment. However, because of the FIFO rule, these orders closes the oldest positions first, not the position you have attached the orders to. So, in case you recognize the whole amount on particular instrument/account as one netting position, these orders works good enough. ELS orders cannot be used on non-FIFO accounts.

Description |

EntryLimitStop |
string |
Set the value of this field to "Y" or "y" to create ELS limit/stop orders on a FIFO account. Please note, that, unlike the regular stop and limit orders, each order in ELS orders batch has it's own
request id. So, the Examples: The If you need to find an association between orders and trades, please use CustomID field of the request. |
||||
RateStop |
number |
The price level of the stop order. The stop order must be below the trade price for the position created using a buy order (long position) and above the trade price for the position created using a sell order (short position). Either |
||||
PegTypeStop |
string |
"Pegged" means that the price is specified as an offset (in pips) against the market price. The field specifies which price should be used to calculate the order price:
|
||||
PegPriceOffsetPipsStop |
number |
Offset to the price specified in the The offset must be positive for a sell position and negative for a buy position. |
||||
TrailStepStop |
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 The value is optional. By default, this value is 0. 0 means no-trailing order. |
||||
RateLimit |
number |
The price level of the limit order. The limit order must be above the trade price for the position created using a buy order (long position) and below the trade price for the position created using a sell order (short position). Either |
||||
PegTypeLimit |
string |
"Pegged" means that the price is specified as an offset (in pips) against the market price. The field specifies which price should be used to calculate the order price:
|
||||
PegPriceOffsetPipsLimit |
number |
Offset to the price specified in the The offset must be negative for a sell position and positive for a buy position. |
