Two of the most important Smart Money Concepts sound similar and confuse almost every beginner: Break of Structure (BoS) and Change of Character (CHoCH). Get them straight and the rest of SMC starts to click. The short version: BoS says the trend continues; CHoCH says it’s reversing.
Break of Structure (BoS): trend continuation
A BoS happens when price breaks through a previous significant high or low in the direction of the existing trend.
- Bullish BoS: in an uptrend, price breaks above the most recent swing high. Buyers are still in control; the uptrend likely continues. Look for longs on the next pullback.
- Bearish BoS: in a downtrend, price breaks below the most recent swing low. Sellers remain dominant. Look for shorts on the next rally.
BoS is a confirmation tool. It tells you “yes, the trend you’re seeing is real — keep trading in this direction.”
Change of Character (CHoCH): trend reversal
A CHoCH — also called a Market Structure Shift (MSS) — is the first signal that the trend is turning. It’s arguably the most valuable SMC concept because it catches reversals early.
- Bullish CHoCH: during a downtrend (lower highs, lower lows), price breaks above a recent lower high for the first time. First evidence buyers are taking over.
- Bearish CHoCH: during an uptrend, price breaks below a recent higher low for the first time. First sign sellers are taking control.
The key difference
Think of it directionally relative to the current trend:
- BoS breaks structure in the same direction as the trend → continuation.
- CHoCH breaks structure against the trend → potential reversal.
When a CHoCH is followed by a BoS in the new direction, you have strong evidence a fresh trend has begun.
How to trade a CHoCH
A CHoCH alone is an early signal, so the safer play is to wait for price to retrace into a nearby order block or fair value gap, then enter in the new trend’s direction. Put your stop just beyond the broken structure and target the next significant liquidity level.
CHoCH is also a powerful exit tool: if you’re long and price CHoCHs against you, that’s a strong reason to close immediately rather than waiting for your stop.
Confirm with closes, not wicks
One crucial detail: for a valid break, you want the candle to close beyond the level — not just poke through with a wick. Closes confirm intent; wicks are often just noise. (More on reading wicks in our candlesticks guide.)
