Understanding Break of Structure (BoS) and Change of Character (CHoCH) in Trading
Deep dive into the theory and advanced applications of BOS and CHOCH for professional market analysis.
Break of Structure (BOS) and Change of Character (CHOCH) Trading Strategy
Last Updated: October 28, 2025
Understanding market structure is crucial for making informed decisions and maximizing profits. Two fundamental concepts that every trader should grasp are break of structure (BOS) and change of character (CHOCH). These concepts form the backbone of the CHOCH and BOS trading strategy, enabling traders to identify trend reversals and continuations with precision. In this comprehensive guide, we'll delve deep into these concepts, explore their interplay, and demonstrate how to leverage them effectively using tools like TradingView.
What is Break of Structure (BOS) in Trading?
A break of structure (BOS) occurs when the price moves beyond a swing high in an uptrend or a swing low in a downtrend. The break of structure signals trend continuation and is a sign that the bulls are in control (uptrend) or that the bears are in control (downtrend).
Break of Structure (BOS) in an uptrend.
Types of BOS
Bullish Break of Structure: This happens when the price breaks above a previous high in an uptrend, suggesting the continuation of the bullish trend.
Bearish Break of Structure: This occurs when the price breaks below a previous low in a downtrend, indicating the potential continuation of the bearish trend.
Example of BOS
Consider an uptrend where the market consistently makes higher highs and higher lows. A BOS is identified when the price surpasses the latest high, confirming the strength of the uptrend. Conversely, in a downtrend, a BOS is confirmed when the price drops below the latest low, reinforcing the bearish momentum.
Understanding Change of Character (CHOCH)
A change of character (CHOCH) signifies a shift in the market trend. Unlike BOS, which focuses on breaking previous levels, CHOCH highlights the failure of the current trend to maintain its momentum, leading to a potential reversal.
Change of Character (CHOCH) leading to a new potential downtrend.
Types of CHOCH
Bullish CHOCH: Occurs in a downtrend when the price breaks above the most recent lower high. This break confirms the Change of Character and signals a potential reversal to the upside.
Bearish CHOCH: Occurs in an uptrend when the price breaks below the most recent higher low. This break confirms the Change of Character and signals a potential reversal to the downside.
Example of CHOCH
In an uptrend, if the price breaks below a recent low, it signals a CHOCH, indicating that the bullish trend may be reversing. Similarly, in a downtrend, if the price breaks above a recent high, it points to a bullish CHOCH, suggesting a possible bullish reversal.
Integrating BOS and CHOCH: The CHOCH and BOS Trading Strategy
The CHOCH and BOS trading strategy combines both concepts to provide a robust framework for trading decisions. By identifying BOS and CHOCH, traders can better anticipate market movements and execute trades with higher accuracy.

📋 5-Step Implementation Process
1
Identify the Current Market Trend
Determine whether the market is in an uptrend, downtrend, or sideways movement. This establishes your baseline for analysis.
2
Monitor for BOS
Look for price breaking above recent highs or below recent lows, indicating potential trend continuation and momentum strength.
3
Watch for CHOCH
Observe when price fails to maintain higher lows (uptrend) or lower highs (downtrend), signaling possible trend reversal.
4
Confirm with Additional Tools
Use complementary indicators like MACD, RSI, or Price Action analysis to validate your BOS and CHOCH signals before entering trades.
5
Execute with Risk Management
Enter trades based on confirmed signals while setting appropriate stop-loss and take-profit levels to protect your capital.
⏱️ Internal vs. External BOS and CHOCH
Understanding the distinction between internal and external market structure is essential for refining your trading strategy and timing your entries.
External BOS & CHOCH
Higher Timeframes
Timeframes: Daily, Weekly, Monthly charts
Significance:
- Carry more weight in market analysis
- Indicate significant market shifts
- Define major trend changes
- Guide overall trading direction
Best For: Identifying primary market trends and major reversal points
Internal BOS & CHOCH
Lower Timeframes
Timeframes: 15-min, 1-hour, 4-hour charts
Significance:
- Provide early warning signals
- Enable precise entry timing
- Help optimize exit points
- Identify short-term opportunities
Best For: Fine-tuning entries and exits within the larger trend
Pro Tip: Multi-Timeframe Alignment
For highest probability trades, align external BOS/CHOCH signals from higher timeframes with internal signals from lower timeframes. When both confirm the same direction, trade confidence increases significantly.
Steps to Implement the CHOCH and BOS Trading Strategy
Identify the Current Market Trend: Determine whether the market is in an uptrend, downtrend, or sideways.
Monitor for BOS: Look for instances where the price breaks above a recent high or below a recent low, indicating a potential trend continuation.
Watch for CHOCH: Observe when the price fails to maintain higher lows in an uptrend or lower highs in a downtrend, signaling a possible trend reversal.
Confirm with other Tools: Use trading tools like the MACD Indicator, or Price Action to combine with Break of Structure and Change of Character.
Execute Trades with Proper Risk Management: Enter trades based on BOS and CHOCH signals while setting appropriate stop-loss and take-profit levels to manage risk effectively.
Internal vs. External BOS and CHOCH
Understanding the distinction between internal and external BOS and CHOCH is essential for refining your trading strategy.
External BOS and CHOCH
External BOS and CHOCH refer to breaks and changes in the higher time frames, such as daily or weekly charts. These signals often carry more weight and indicate significant market shifts.
Internal BOS and CHOCH
Internal BOS and CHOCH occur within lower time frames, like hourly or 15-minute charts. These can provide early warnings of potential trend changes and are invaluable for timing entries and exits more precisely.
Internal Break of Structure (iBoS), Internal Change of Character (iCHoCH), External Break of Structure (eBoS) and External Change of Character (eCHoCH)
Practical Application with TradingView

Why Market Structure Trading Matters
Market structure trading revolves around understanding the patterns and behaviors of price movements within the market. By mastering BOS and CHOCH, traders can:
Identify Trend Continuations and Reversals: Recognize when a trend is likely to continue or reverse, allowing for timely trade entries and exits.
Enhance Trade Accuracy: Increase the probability of successful trades by confirming signals across multiple time frames.
Improve Risk Management: Set more precise stop-loss and take-profit levels based on the identified market structure.
