TL;DR

User Session (AutoForward's approach) accesses private channels without Admin rights and achieves sub-1-second latency. Bot API is simpler but completely blocked from private channels — a fatal limitation for signal copy trading.

When to Use Each

Use Bot API when: Building interactive bots, source is Public Channel where you're Admin, no history access needed. Use User Session (AutoForward) when: Source is Private Channel/Group, you're not an Admin, need lowest latency, want no-code setup.

FAQ

Is User Session safe? Can Telegram ban my account?

AutoForward mimics normal user behavior. Telegram doesn't prohibit reading and forwarding messages. Thousands of users do this daily. Avoid forwarding more than 20 messages/minute per session.

Is my session token secure?

Sessions are Fernet-encrypted and stored securely. AutoForward never shares sessions with third parties.
