Testing in sandbox

In sandbox, Orders are filled by a simulator, instead of an actual execution venue.

Filling orders after hours

Orders placed outside of market hours, like equities Orders placed overnight, will be filled at market open, like they would be in production. However, if you would like to test an immediate execution, even outside of market hours, set a special flag on the Account you’re testing in:

PATCH /back-office/accounts/{accountID}
{
	"ignoreMarketHoursForTest": true
}

This can be particularly helpful for Continuous Integration purposes.

Magic numbers

To assist in testing specific Order workflows, the following combinations of symbols and quantities can be used to force certain behavior:

Symbol	Quantity	Handling
HL	176	Execute only half of the quantity, and exchange cancel the remainder
HL	177	Execute in two fills, at two different prices
HL	178	Execute in 10 share increments, for a total of 18 fills
HL	179	Execute in 20 share increments and send a new fill every 1 second
HL	1019	Execute fully, no different from typical execution
HL	1039	Execute 1 share at a time
HL	1049	Execute 100 shares at a time
HL	1059	Returns NOS NAK or failure
HL	1069	Execute a partial amount, exchange cancel remainder
HL	1079	Execute nothing, exchange cancel everything
HL	1089	Execute nothing, leave open and awaiting cancel
HL	5089	Execute nothing, leave open and await cancel request

These quantities can be used for a buy-side order only:

POST /back-office/orders
{
    "accountNo": "DWCU000440",
    "orderType": "MARKET",
    "symbol": "HL",
    "side": "BUY",
    "quantity" : 1011
}
