# OANDA API GET /v3/instruments/{instrument}/candles

Independent and unofficial. Not affiliated with or endorsed by any broker or platform named here. Educational only: nothing here is advice, and nothing here recommends a broker or a trade.

This is the markdown version of https://openbrokerapi.com/brokers/oanda/endpoints/candles, written from the same records as that page.

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.

Historical candlesticks (OHLC) for one instrument. Up to 5000 candles per request.

- Request: `GET /v3/instruments/{instrument}/candles`
- Version: v3
- Group: Instruments
- Status: unverified. Source: [raw.githubusercontent.com](https://raw.githubusercontent.com/oanda/v20-openapi/master/json/v20.json), checked 2026-10-12.
- Official reference: https://developer.oanda.com/rest-live-v20/pricing-ep/

Note: Not verified on OANDA's own site today. The instrument endpoints page this record was read on (developer.oanda.com/rest-live-v20/instrument-ep/) answered 404 on 12 Oct 2026 and the site's menu no longer lists it. That is not evidence that the call has gone. OANDA's own OpenAPI file on GitHub (oanda/v20-openapi, version 3.0.25), opened the same day, still defines GET /instruments/{instrument}/candles under the base path /v3 with the parameters listed here, and is the source linked on this record. What OANDA's site documents today is the account scoped call, GET /v3/accounts/{accountID}/instruments/{instrument}/candles, on its pricing endpoints page: the same query parameters plus units, with count defaulting to 500 and capped at 5000.

## Parameters

## Limits that apply at OANDA

- Headline limit: 120/s per IP address, HTTP 429 above it
  - Scope: ip
  - Status: verified. Source: [developer.oanda.com](https://developer.oanda.com/rest-live-v20/development-guide/), checked 2026-10-03.
  - Note: Best practices. Also 2 new connections a second. The development guide separately states 120 requests a second per IP address, read 24 Sep 2026; the two figures are in different units and neither replaces the other.
