OANDA API GET /v3/accounts/{accountID}/pricing/stream

GET/v3/accounts/{accountID}/pricing/streamversion v3Pricing

Streaming prices over one long lived HTTP connection. Newline delimited JSON: PRICE and HEARTBEAT objects.

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 unofficialdeveloper.oanda.comchecked 12 Oct 2026

Confirmed on the official pricing endpoints page. Method, path and request parameters were re-read on that page on 12 Oct 2026 and agree with this record; the mock reply was not compared field by field. Served by the stream host (stream-fxpractice.oanda.com or stream-fxtrade.oanda.com), not the REST host. At most 4 prices per second per instrument (every 250 ms); heartbeats every 5 seconds. Mock shows stream lines as an array for display only.
