This is just the superficial meaning of common English words. Many platforms are mostly common. Demo is generally an analog server, and live or real is the account of the real server. The IFX platform you mentioned is not very clear. Generally, it is a platform that is not regulated by FCA, NFA, ASIC, etc. It is not recommended to choose, so I can only say so much and hope to adopt it. If the landlord is the salesman of this platform, ignore it, just to ask yourself and answer.
