Break of structure vs change of character: BOS vs CHoCH
Both are breaks of a swing high or low. The difference is direction: one confirms the trend, the other is the first warning that it might be over.

Smart Money patterns at a glance
Bearish
Change of Character
The first break against the trend — the earliest warning that control is shifting.
Bullish
Order Block retest
The last opposite candle before a displacement, retested as demand.
Bullish
Liquidity sweep
Price runs the stops under equal lows, then closes back inside — trapped sellers fuel the move.
Bullish
Fair Value Gap
A three-candle imbalance. Price often returns to rebalance it before continuing.
Bearish
Trendline break
An automatic trendline from swing points, flagged when a candle closes through it.
Market structure in one minute
An uptrend makes higher highs and higher lows. A downtrend makes lower highs and lower lows. Swing highs and swing lows are the turning points between legs. Everything in Smart Money Concepts starts from reading those points correctly.
Break of structure (BOS)
A break of structure happens when price breaks the last swing point in the direction of the trend:
- In an uptrend, price closes above the last swing high: a bullish BOS.
- In a downtrend, price closes below the last swing low: a bearish BOS.
A BOS is a continuation signal. It confirms the trend is still intact.
Change of character (CHoCH)
A change of character is the first break against the trend:
- In an uptrend, price closes below the last higher low: a bearish CHoCH.
- In a downtrend, price closes above the last lower high: a bullish CHoCH.
A CHoCH is an early reversal warning. It does not prove the trend has turned, but it says the old pattern of highs and lows has broken.
BOS vs CHoCH at a glance
| BOS | CHoCH | |
|---|---|---|
| Direction | With the trend | Against the trend |
| Meaning | Trend continues | Trend may be reversing |
| Typical use | Join the trend on pullbacks | Prepare for a reversal, tighten stops |
Example (illustrative): a coin makes higher highs at 10.0, 10.8 and 11.5, with higher lows at 9.6 and 10.3. A close above 11.5 would be a BOS. Instead price drops and closes below 10.3, the last higher low. That is a bearish CHoCH. If it then makes a lower high and breaks below the next low, the downtrend is confirmed by a bearish BOS.
How traders use them
- Trend entries: after a BOS, wait for a pullback into an order block or fair value gap and join the trend.
- Reversal entries: after a liquidity sweep of a key high or low, a CHoCH on a lower timeframe is the trigger many traders wait for.
- Timeframes: structure on the 4h and daily sets the bias; BOS and CHoCH on 5m–15m time the entry. See multi-timeframe analysis.
Common pitfalls
- Counting wicks as breaks. Most traders require a candle close beyond the swing.
- Using tiny internal swings. Decide which swing size you are tracking and stay consistent.
- Treating every CHoCH as a reversal. Many are just deep pullbacks.
Scanning for BOS and CHoCH
Trend continuation
4h Break of Structure = bullish AND 15m Order Block Retest = bullish
Higher-timeframe trend confirmed, lower-timeframe entry on a retest.
Reversal after a sweep
Liquidity Sweep = bullish AND Change of Character = bullish
Stops below a low taken, then the first break against the downtrend.
Frequently asked questions
What is the difference between BOS and CHoCH?
A break of structure (BOS) breaks a swing point in the direction of the trend and signals continuation. A change of character (CHoCH) is the first break against the trend and warns of a possible reversal.
Is a CHoCH a reversal signal?
It is an early warning, not a confirmation. A reversal is usually confirmed when price makes a new swing in the opposite direction and then breaks structure that way.
Do wicks count as a break of structure?
Most traders require a candle close beyond the swing high or low. A wick that pokes through and closes back inside is more often a liquidity sweep.
