Break of structure (BOS)
Also known as: BOS, market structure shift, CHoCH
A break of structure is price breaking a prior swing high or low, confirming trend continuation; a break against the trend is a change of character (CHoCH) that warns of a reversal.
Market structure is the sequence of swing highs and lows. A BOS in the trend direction confirms continuation; a CHoCH is the first sign the trend may be turning. Both are used to set bias and validate order blocks and fair value gaps.
