Give each timeframe a job
Use a higher timeframe for broad location, a working timeframe for structure and a lower timeframe only when finer execution detail is genuinely needed.
Avoid collecting contradictions
Adding more charts can create more opinions without adding information. Decide in advance which timeframe has authority when signals disagree.
Keep the plan anchored
An entry on a small timeframe should not silently turn into a long-term position. The invalidation and review schedule should follow the original plan.
