# cTrader API: questions and answers 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/answers/ctrader, 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. 6 questions about the cTrader API, each answered from the cTrader record on this site (https://openbrokerapi.com/platforms/ctrader) and nothing else. - Newest check: 2026-10-12 - Official documentation: [help.ctrader.com](https://help.ctrader.com/open-api/) An answer here is the record's own wording, cut at the end of a sentence, or a list of names read from records.
