Bullish Break of Structure
A Bullish Break of Structure (BOS) is a price action concept signaling continuation of an uptrend when price closes decisively above a prior swing high, confirming buyers remain in control of the market structure. It’s a foundational price action concept used in Smart Money / ICT-aligned analysis.
Definition
Bullish BOS occurs when the price decisively breaks above a recent swing high without first breaking the prior swing low, confirming ongoing bullish trend continuation. This indicates that buy pressure is strong enough to push past the previous structure, suggesting further upward momentum.
Why It Matters
Bullish BOS confirms that an uptrend has strength and is intact, helping traders align entries with market structure continuation rather than guesswork. It also filters out weak or false signals when price fails to break key structural highs.
How to Identify
- Identify the most recent valid swing high level on the chart.
- Mark the prior swing low that must remain intact for a valid bullish continuation.
- Confirm price closes above the swing high level with conviction (not just intrabar wicks).
- Verify that the prior swing low has not been broken before identifying the break.
- Higher timeframe alignment improves signal quality (uptrend context).
How to Trade
- Confirm higher-timeframe bullish bias (higher highs/higher lows).
- Enter long on retest of the broken swing high or after a retrace into structure/PD array following BOS.
- Place the stop below the protected swing low or below the pullback low after BOS.
- First target near the next structural level; additional targets at PDH/PDL or liquidity pools.
- Trail stops as new structure highs form to protect gains.
Common Confusions
IF price only pokes above swing high intrabar but closes inside THEN do not signal BOS. IF price *closes* above the swing high sufficiently THEN BOS is confirmed.
IF price breaks above previous swing high THEN this is continuation bias (bullish). IF price breaks below previous swing low THEN it is bearish BOS or potential reversal context.
IF prior swing low is broken before or near the same time as the high is broken THEN structure is not clearly bullish. BOS requires higher high with protected low.
IF price breaks previous swing low in an uptrend THEN CHoCH is indicated (reversal bias). IF price breaks previous swing high THEN BOS indicates continuation.
Pre-Trade Checklist
- Uptrend established on HTF?
- Prior swing high clearly identified?
- Price broke above swing high with body close?
- Swing low protected (not broken)?
