Break of Structure, often shortened to BOS, is one of the most practical concepts in technical analysis because it helps traders spot the moment price stops respecting its previous rhythm. In simple terms, a bullish BOS forms when price breaks above a previous structural high. A bearish BOS forms when price breaks below a previous structural low.
Yet the real value is not in the break alone. The edge comes from understanding where the break happens, what created it, and whether the move has real intent behind it. Many traders treat every broken high or low as a signal. Experienced traders slow down, read the context, and become far more selective.
