Break of Structure
Also called: bos, structure break
When price breaks above a prior swing high (bullish BoS) or below a prior swing low (bearish BoS) — the moment a trend confirms or reverses.
USD/JPY printed a clear bearish BoS in July 2024 when the daily chart broke below the 158.30 higher low. The retest at 158.20 the following day delivered a clean short entry that ran to 145 — over 1,300 pips of follow through.
