Phone-friendly control matters
A mobile workflow should let users review signals, pause channels, and check account state without needing a desktop screen for every decision.
Do not assume a Mini App
Some searches mention Telegram Mini Apps. Tragram pages should only describe a Mini App if that product workflow is actually available.
Web access can still help
A responsive web dashboard can support monitoring and review from a phone while keeping the actual MT4/MT5 workflow tied to the connected account.
