CMC Markets API: questions and answers
3 questions about the CMC Markets API, each answered from the CMC Markets record on this site and nothing else.
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.
An answer here is the record's own wording, cut at the end of a sentence, or a list of names read from records. An answer that opens with the word Unverified has no dated source behind it. Where this page and the provider's own documentation differ, the documentation wins. Nothing here recommends a broker.
