Planned Changes

Overview of planned changes:

Non-Breaking  – 1 minute horizon charts reduced to 6 month history (From Oct. 23 2026 [SIM], expected Nov. 3 2026 [LIVE])

Charts data for all instruments has been reduced to 6 month history for 1 minute horizon candles, already effective in simulation 

If data is requested from over 6 months ago for a horizon of 1, then no data for that time period will be returned.

Breaking - Reject Corporate Action Election Fractional Amounts (From December 1st 2026)

Effective December 1st, 2026, corporate action elections will reject request bodies with fractional amounts

PUT ca/v2/elections

Property: Options[].Amount


Currently fractional amount are accepted in the request but are rounded down in underlying systems. 

This change does not alter the behavior of elections on fractional amounts, but it is intended to clarify how fractional amounts are handled by Saxo Bank.

Breaking - New Onboarding Requirements in the Client Management Service (From January 1st 2027)

Effective January 1st, 2027, new fields and documents will be required for all newly onboarding clients. 

In '/cm/v1/signups', this includes 3 additional fields  'ConsentForTaxRelief', 'UsExpiryYear', and 'UsTaxDocumentation" within the RegulatoryInformation → FactaDeclaration object.

Additionally in '/signups/attachments', there are 2 new document types 'UsTaxForm' and 'CrsStatus' under SignupFlowDocumentType.

Breaking - Removal of root/v1/user (From September 1st 2026)

The endpoint root/v1/user has been replaced by root/v2/user.

The documentation for the new endpoint can be found here: root/v2/user.

Please ensure that you migrate to this new endpoint before the deadline, otherwise your application might stop working correctly.

Breaking - Removal of ca/v1/proxyvoting/events (From May 31st 2026)

The endpoint ca/v1/proxyvoting/events is being replaced with the ca/v2/proxyvoting/events endpoint.


You can find the replaced endpoints and more in our reference documentation: 

https://www.developer.saxo/openapi/referencedocs/ca/v2/proxyvoting

This includes changes to ensure confirmation of display of proxy fees, before linking towards the external proxy voting event.

Breaking - Enforcement of pre-trade disclaimers (from May 2025)

Handling of pre-trade disclaimers will become mandatory for all OpenAPI apps from May 2025, so it's important to implement proper support for it in your OpenAPI Application as soon as possible.

Read more about this change here: Breaking Change - Pre-Trade Disclaimers on OpenAPI

Failure to properly handle pre-trade disclaimers in your application will lead to orders being rejected. Even if no disclaimers are present for your user at this time, they can be added at any time without warning.
