Broker API changes, week 22 2026
3 dated changes from 25 May 2026 to 31 May 2026, grouped by broker or platform. Each one links the page it was read on.
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.
