Independent and unofficialNewest reading Official documentation

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.

Access, authentication and streaming

API types listed in the record: FIX (CMC Connect, institutional only).

How you get a key

Platform access only for retail clients, on the pages opened. CMC's UK platforms page offers its own web platform, its mobile app and MetaTrader 4, and the MT4 page presents Expert Advisors as the way to automate. An API appears only on CMC Connect, the institutional side, which offers market data and trade execution over the FIX protocol, either through a direct API or through a third party technology hub. No page opened on 12 Oct 2026 offers an API to retail clients, which is what the pages show and not a statement by CMC that none exists.

Demo

Platform demo only: an MT4 demo account with GBP 10,000 of virtual funds, which stays open as long as you log in to MT4 at least once every 30 days. It is a demo of the platform, not of an API. The CMC Connect page does not say whether a test FIX session is offered.

Rate limits, as worded

No retail API on the pages opened. CMC Connect offers market data and execution through the FIX protocol to institutional clients, and its connectivity page states no rate limit (re-read 12 Oct 2026). A page that states no limit is not evidence that there is none.
