In trading, understanding market structure is essential to spot trend changes and make smarter trading decisions. Two key concepts for this are CHOCH and BOS, along with the classic Higher Highs (HH), Higher Lows (HL), Lower Highs (LH), and Lower Lows (LL).
1. What is a Market Shift?
A market shift happens when the price action shows a change in trend.
Uptrend: HH + HL → Buyers are in control
Downtrend: LL + LH → Sellers are in control
A market shift signals that control might be moving from buyers to sellers, or vice versa.
2. Higher Highs and Higher Lows (Uptrend)
Higher High (HH): Each new peak is higher than the previous one.
Higher Low (HL): Each new dip is higher than the previous one.
When the price keeps making HH and HL, it shows that buyers are strong, and the uptrend is intact.
3. Lower Lows and Lower Highs (Downtrend)
Lower Low (LL): Each new dip is lower than the previous one.
Lower High (LH): Each new peak is lower than the previous one.
This pattern indicates sellers are in control, and the price is likely to continue downward.
4. BOS (Break of Structure)
BOS occurs when the price breaks a previous key high or low, signaling a potential continuation in the trend:
Bullish BOS: Price breaks above previous HH → Uptrend continues
Bearish BOS: Price breaks below previous LL → Downtrend continues
Think of BOS as a confirmation of trend strength.
5. CHOCH (Change of Character)
CHOCH is the first sign that a trend might be reversing:
In an uptrend: Price fails to make a new HH and drops below a previous HL → Potential trend reversal
In a downtrend: Price fails to make a new LL and rises above a previous LH → Potential trend reversal
CHOCH helps traders spot early signs of market shifts before the trend fully changes.
6. How to Spot a Market Shift
A market shift is confirmed when:
Structure breaks (BOS)
Character changes (CHOCH)
Volume and momentum support the move
Example:
Uptrend makes HH + HL consistently → CHOCH occurs when a candle closes below previous HL → Potential reversal
Downtrend makes LL + LH consistently → CHOCH occurs when a candle closes above previous LH → Potential reversal
7. Why This Matters
Helps avoid entering trades against the trend
Allows better timing for entries and exits
Detects early signals of trend reversals, giving you an edge over other traders
8. Key Takeaways
Watch Highs and Lows carefully
Look for BOS to confirm trend continuation
Watch for CHOCH to spot early reversals
Combine with volume and momentum for confirmation
Understanding CHOCH, BOS, HH, HL, LL, and LH gives you the tools to read market structure and trade more confidently.
