Broker API changes, week 23 2026
1 dated change from 1 Jun 2026 to 7 Jun 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.
