BOS vs CHoCH: What's the Difference?
These two terms confuse almost every new smart-money trader. Simply: a BOS (break of structure) confirms the trend is continuing, while a CHoCH (change of character) is the first break against the trend — the earliest hint of a reversal. Same idea (price breaking a structural level), opposite meaning.
BOS — with the trend
A BOS happens when price breaks a prior swing point in the direction of the trend: a new higher high in an uptrend, or a new lower low in a downtrend. It says “the trend is still in control.” Traders use it as confirmation to keep trading with the trend. Full BOS guide →
CHoCH — against the trend
A CHoCH is the first break against the trend: an uptrend breaking its last higher low, or a downtrend breaking its last lower high. It signals momentum may be shifting and a reversal could be starting. Full CHoCH guide →
How to tell them apart
- Ask: is the break with the current trend or against it?
- With the trend = BOS (continuation).
- Against the trend = CHoCH (possible reversal).
- A CHoCH often comes right after a liquidity sweep; a fresh BOS in the new direction then confirms the reversal.
Putting it together
A clean sequence looks like: trend up (BOS, BOS), liquidity sweep of the highs, then a CHoCH down. That CHoCH is your heads-up; you wait for a BOS in the new (down) direction to confirm, then look for entries from an order block or FVG. Read them together and market structure becomes a map.

What is the difference between BOS and CHoCH?
BOS is a break in the direction of the trend (continuation); CHoCH is the first break against the trend (possible reversal). Both are structure breaks — the direction relative to the trend is what changes their meaning.
Which comes first, BOS or CHoCH?
In a reversal, the CHoCH comes first (the first counter-trend break), then a BOS in the new direction confirms the trend has actually flipped.
