Start with observable swings
Market structure begins with the sequence of visible highs and lows. Higher highs and higher lows describe an advancing market; lower highs and lower lows describe a declining one. The labels are descriptions—not predictions.
Separate trend from transition
A single broken swing does not always establish a new trend. Treat it as evidence of transition, then look for acceptance, follow-through and the behaviour of the next pullback.
Use structure as context
Structure is most useful for deciding where an idea belongs, where it no longer makes sense and which timeframe should govern the plan.
