Broker API changes, weekly editions

121 dated changes across 53 weeks, newest first. A week appears here only if a change is dated inside it.

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.

A week runs Monday to Sunday and is numbered as ISO 8601 numbers it. A change is filed under the week that holds its own date, as its source gives it, which is not always the week this site read it.
