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.
A break of structure is the moment market structure changes direction. In an uptrend, a bearish break of structure happens when price drops below the most recent higher low — that's the first confirmation the uptrend may be over. In a downtrend, a bullish break of structure happens when price rallies above the most recent lower high.
BoS is one of the cornerstone concepts of Smart Money / ICT trading. It tells you when to flip your bias. Until structure breaks, the trend is still in force. Once structure breaks, you start looking for setups in the new direction.
The entry technique is to wait for a pullback after the BoS. Don't chase the break — wait for price to retest the broken level (now flipped from support to resistance, or vice versa) and enter on confirmation. This gives you a clean stop and a measurable target.
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.
Frequently asked about break of structure
What is a break of structure in trading?+
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.
When will I see break of structure used in real trading?+
At every trend reversal, after every major news event, and at every key support or resistance break.
What is the most common mistake traders make with break of structure?+
Trading the BoS candle itself instead of waiting for the retest. The BoS is the signal — the retest is the entry. Chasing the break gets you bad fills and tight stops that get hunted.

Higher timeframe BoS (daily/weekly) is far more reliable than lower timeframe BoS (5m/15m). Always check the higher chart before trading a break — make sure the higher timeframe agrees.
