What Actually Makes Protected Highs And Lows?

A setup can look perfect on a screenshot and still fail over a meaningful sample. I would define the rules before looking at results, record every qualifying trade, and compare outcomes across different market conditions. What metrics would you require before trusting this idea with real risk? My preference is to treat this as a hypothesis, not a promise of profit. A transparent journal and realistic execution assumptions are more convincing than a polished screenshot or a confident claim from a popular account. In your experience, what specific rule or metric best separates disciplined use of this market structure topic from guesswork?
