AI trading bot in 2026 — what stack is real for retail vs marketing?

When people google "AI trading bot" they get signal Telegram channels and course funnels.

What stacks have you actually run for 90+ days?
- Classic EA + regime filter
- ML feature model → signals into MT5
- LLM research helper only (no live orders)
- Mandate / agentic workflows like Agentic Trading
- Analyst scoreboards like WorldBot.Club as veto-only input

Please separate "helped research" from "ran live with measured edge".
