DXtrade API POST /accounts/{accountCode}/orders

POST/accounts/{accountCode}/ordersTrading

Place a market, limit or stop order, or a group of orders, on an account. The client gives each order a code of its own so a repeat is refused.

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Independent and unofficialdemo.dx.tradechecked 12 Oct 2026

Read on 12 Oct 2026 in the DXtrade REST API specification on DXtrade's developer portal. The portal draws its pages in the browser from Markdown files it also serves directly, and the Markdown file of this page (DXtrade-REST-API.md) is what was read, with the model files it includes. The portal writes each address after a base address it fills in from its own settings, which on this portal is https://demo.dx.trade/dxsca-web. A broker or firm that offers DXtrade hosts its own, so the path here is what follows that base. The page writes the placeholder in the address as {account code} and names the parameter accountCode or account code. This record uses accountCode. The specification says every request needs authentication unless it says otherwise, and this section says the Authorization header should be included, which is why it is recorded as required. The body fields are those of the Single Order Request model, with the model's own required and optional marks. The page also accepts an Order Group Request, which is not recorded here. The call is not idempotent: the page says an order code that already exists is refused with 409 and error code 100. The reply is an Order Response, whose orderId and updateOrderId are both marked required. The mock reply uses those names with invented values.

Parameters

Name	In	Type	Description
accountCoderequired	path	string	The account code, two strings joined by a colon in the form clearing:account, assigned by the platform. URL-encode it.
orderCoderequired	body	string	An identifier for the order, unique among the orders on the account. For a new order the client assigns it.

siderequired	body	string	One of: BUY, SELL.
quantity	body	number	Marked optional. The size in units, not lots. Left out or zero for a closing order tied to a position, which takes the position's size.
positionEffect	body	string	Marked optional. One of: OPEN, CLOSE. The model says it is required for position based trading.
positionCode	body	string	Marked optional. The position the order changes. Present when positionEffect is CLOSE and left out otherwise.
limitPrice	body	number	Marked optional. The price of a limit order. Absent for market and stop orders.
stopPrice	body	number	Marked optional. The price of a stop order. Absent for market and limit orders.
priceOffset	body	number	Marked optional. A price offset for a protection order, taken from the fill price of the order that triggers it. Needs priceLink.
priceLink	body	string	Marked optional. One of: TRIGGERED_STOP, TRIGGERED_LIMIT.
tif	body	string	Marked optional. Time in force. One of: GTC, DAY, GTD. The default depends on how the platform is set up.
expireDate	body	string	Marked optional. Expiry in UTC. Present when tif is GTD and left out otherwise.
metadata	body	object	Marked optional. Up to 32 key and value pairs of the client's own, stored and returned with the order.

Authentication headers

Name	Type	Description
Authorizationrequired	string	With token authentication, send DXAPI followed by the sessionToken from POST /login. With HMAC authentication the same header carries DXAPI with a principal, a timestamp and a hash, signed for each request as the specification describes. Placeholder only: never paste a real token into this site.

Request

Written from the method, path and parameters recorded on this page. No demo host is recorded as a plain address for this API, so the samples read the base address from an environment variable. Not executed against a live or demo account. Credentials are read from environment variables on your own machine and are never entered on this site. The request builder writes these same snippets, from the same record.

This call takes a request body. The samples send it as JSON with a Content-Type of application/json (in Python, passing json= sets that header) and a placeholder for each of the 4 body fields the record marks as required. Each placeholder has to be replaced with a real value before the request can succeed.

Python

# DXTRADE_SESSION_TOKEN holds the Authorization header that POST /login returns.
# No demo host is recorded as a plain address for this API, so the base address is read from DXTRADE_BASE_URL.
# Replace each {placeholder}, "..." and 0 with a real value before running.
# Optional and not shown: body fields quantity, positionEffect, positionCode, limitPrice, stopPrice, priceOffset, priceLink, tif, expireDate, metadata.
