TradeLocker API POST /trade/accounts/{accountId}/orders

POST/trade/accounts/{accountId}/ordersTrading

Place a market, limit or stop order on the account, with an optional stop loss and take profit. The reply carries the new orderId.

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.

Read on 12 Oct 2026 on TradeLocker's own reference page for this call, in the Markdown version the documentation site serves at the same address with .md on the end. That page carries the call's OpenAPI definition, headed Trading API version 2.11.0: the method, path, parameters and required marks here are that definition's. The reference names the optional header developer-api-key, while TradeLocker's getting started page calls the Developer Program key tl-developer-api-key and says it unlocks less restrictive rate limits. This record keeps the name on the reference page. An accepted order is not a fill: TradeLocker's page on order and position identifiers says a position with its own positionId exists only once the order fills. The mock reply uses the field names of the definition with invented values.

Request

Written from the method, path and parameters recorded on this page, against the demo host. 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 6 body fields the record marks as required. Each placeholder has to be replaced with a real value before the request can succeed.

Python

# Set TRADELOCKER_ACCESS_TOKEN, TRADELOCKER_ACC_NUM as environment variables first. Never paste real values into code.
# TRADELOCKER_ACCESS_TOKEN holds the Authorization header that POST /auth/jwt/token returns.
# Replace each {placeholder}, "..." and 0 with a real value before running.
# Optional and not shown: headers developer-api-key; body fields price, stopPrice, stopLoss, stopLossType, takeProfit, takeProfitType, trStopOffset, strategyId.

}
body = {"qty": 0, "routeId": 0, "side": "...", "tradableInstrumentId": 0, "type": "...", "validity": "..."}
resp = requests.post(BASE_URL + "/trade/accounts/{accountId}/orders", headers=headers, json=body, timeout=10)
