Break of structure and change of character

You will learn to
  • Tell a continuation break from a reversal signal
  • Avoid treating every break as a reversal
  • Wait for the retest

Two kinds of break

Break of structure (BOS): price closes beyond the last swing in the direction of the trend — a new higher high in an uptrend. It confirms continuation.

Change of character (CHoCH): the first close beyond a swing against the trend — in an uptrend, a close below the protected higher low. It is the first warning of a reversal, not a reversal yet.

After a change of character

A reversal needs the opposite structure to build: after the CHoCH, a lower high forms on the bounce, then a lower low. Many traders wait for that lower high and enter there, with the stop above it. Shorting the CHoCH candle itself often means selling the low.

Breaks fail too

Closes beyond a swing by a hair, on low volume, that reverse straight back are failed breaks — often liquidity grabs (next lesson). A strong break closes clearly beyond the level, ideally with a larger body and higher volume, and does not immediately return inside.

The structure drill in the previous lesson trains exactly the swing you must watch: the last higher low in an uptrend, the last lower high in a downtrend.

  1. A change of character
  2. A break of structure (continuation) ✓
  3. A reversal
A break in the trend's own direction confirms it.
2. After a change of character down, where do many traders enter a short?
  1. On the CHoCH candle close
  2. At the lower high that forms on the bounce ✓
  3. At the next all-time high
The lower high confirms the new structure and gives a tight, logical stop.
