BOS vs CHoCH: how to tell if a trend keeps going or turns

Both mean price broke past a turning point. The only question is which way, and that one detail tells you if the trend goes on or may be turning.

First, the turning points

Every chart has places where price turned around. A high is where it stopped rising and turned down. A low is where it stopped falling and turned up. Traders call these swing highs and swing lows. See Swing high and swing low.

An uptrend is a stair-step up: higher highs and higher lows. A downtrend is the reverse: lower highs and lower lows. More in higher highs and higher lows.

BOS and CHoCH are just names for what happens when price breaks one of those turning points.

The body-close rule

This is the one rule that keeps both terms honest: only a candle body closing past the level counts. Wicks don't.

A wick poking past a high and snapping back is often a trap, not a break. Price went to look, found no follow-through and came back. See breakout vs fakeout.

The test: wait for the candle to close. Is the body past the turning point? Yes means a break. Only the wick means not yet.

Break of structure: the trend keeps going

Picture an uptrend. Price makes a high, pulls back to a higher low, then pushes up again. A candle body closes above the last high. That's a break of structure.

What it means for you:

Change of character: the trend may be turning

Now the uptrend keeps going until one day price falls and a candle body closes below the last higher low. The stair-step is broken. That's a change of character.

What it means for you:

Which matters more?

Both, for different jobs:

Many traders wait for a change of character, then for the first break of structure in the new direction, before trading the new trend. That second step is the confirmation.

Common mistakes

Questions

What is the difference between BOS and CHoCH?

A break of structure breaks a turning point in the trend's direction, so the trend keeps going. A change of character breaks one against the trend, so the trend may be turning.

Does a wick count as a break of structure?

No. Only a candle body closing past the turning point counts. A wick that pokes through and snaps back is often a trap.

Is a change of character the same as a reversal?

Not yet. It's an early warning that the old trend may be ending. A new trend is usually confirmed when price breaks a turning point in the new direction.

Which timeframe should I use to spot BOS and CHoCH?

Start with the bigger chart, like the daily or 4-hour, to find the main trend. Then use a smaller chart to time entries in that direction.
